FOREWORD

FOREWORD

Thank you for purchasing the TOPCON Electronic Total Station, GTS-230N series. For the best performance of the instruments, please carefully read these instructions and keep them in a convenient location for future reference.

General Handling Precautions

Before starting work or operation, be sure to check that the instrument is functioning correctly with normal performance.

Do not submerge the instrument into water.

The instrument can not be submerged underwater.

The instrument is designed based on the International Standard IP66, therefore it is protected from the normal rainfall.

Setting the instrument on a tripod

When mounting the instrument on a tripod, use a wooden tripod when possible. The vibrations that may occur when using a metallic tripod can effect the measuring precision.

Installing the tribrach

If the tribrach is installed incorrectly , the measuring precision could be effected.

Occasionally check the adjusting screws on the tribrach. Make sure the base fixing lever is locked and the base fixing screws are tightened.

Guarding the instrument against shocks

When transporting the instrument, provide some protection to minimize risk of shocks.

Heavy shocks may cause the measurement to be faulty.

Carrying the instrument

Always carry the instrument by its handgrip.

Exposing the instrument to extreme heat.

Do not leave the instrument in extreme heat for longer than necessary. It could adversely affect its performance.

Sudden changes of temperature

Any sudden change of temperature to the instrument or prism may result in a reduction of measuring distance range, i.e when taking the instrument out from a heated vehicle. Let instrument acclimate itself to ambient temperature.

Battery level check

Confirm battery level remaining before operating.

Taking the battery out

It is recommended not to take the battery or external battery out during the power is on. All the data stored is possible gone at that time. So please do your assembling or taking the battery out after the power is off.

Do not hold the lower part of display unit

When you take out the instrument from a carrying case, or keep into the case, please hold the hand grip and base of the instrument. Please do not hold the lower part of the display unit.

2.2 Setting Instrument Up For Measurement

Mount the instrument to the tripod. Level and center the instrument precisely to insure the best performance. Use tripods with a tripod screw of 5/8 in. diameter and 11 threads per inch, such as the

Type E TOPCON wide- frame wooden tripod.

Reference: Leveling and Centering the Instrument

1. Setting up the Tripod

First, extend the extension legs to suitable lengths and tighten the screws on their midsections.

2. Attaching the Instrument on the Tripod

Head

Place the instrument carefully on the tripod head and slide the instrument by loosening the tripod screw. If the plumb bob is positioned right over the center of the point, slightly tighten the tripod screw.

3. Roughly Leveling the Instrument by Using the Circular Level

1

Turn the leveling screws A and B to move the bubble in the circular level. The bubble is now located on a line perpendicular to a line running through the centers of the two leveling screws being adjusted.

Leveling screw C

2

Rotate the instrument 90° (100g) around its vertical axis and turn the remaining leveling screw or C to center the bubble once more.

90

Repeat the procedures

1

and

2

for each 90°

(100g) rotation of the instrument and check whether the bubble is correctly centered for all four points.

Leveling screw A

Leveling screw B

5. Centering by Using the Optical Plummet

Telescope

Adjust the eyepiece of the optical plummet telescope to your eyesight.

Slide the instrument by loosening the tripod screw, place the point on the center mark, and then tighten the tripod screw. Sliding the instrument carefully not to rotate that allows you to get the least dislocation of the bubble.

2

Turn the leveling screw C to bring the bubble to the center of the circular level.

4. Centering by Using the Plate Level

1

Rotate the instrument horizontally by using the Horizontal motion/clamp screw and place the plate level parallel with the line connecting leveling screws A and B, and then bring the bubble to the center of the plate level by turning leveling screws A and B.

6. Completely Leveling the Instrument

Leveling the instrument precisely in a similar way to 4. Rotate the instrument and check to see that the bubble is in the center of the plate level regardless of telescope direction, then tighten the tripod screw hard.

Note: 1 The battery operating time will vary depending on the environmental conditions such as ambient temperature, charging time, the number of times of charging and discharging etc. It is recommended for safety to charge the battery beforehand or to prepare spare full charged batteries.

2

For general usage of the battery, see Chapter 14 “POWER SOURCE AND CHARGING”

.

3 The battery power remaining display shows the power level regarding to the measurement mode now operating.

The safety condition indicated by the battery power remaining display in the angle measurement mode does not necessarily assure the battery’s ability to be used in the distance measurement mode.

It may happen that the mode change from the angle mode to the distance mode will stop the operation because of insufficient battery power for the distance mode which consumes more power than angle mode.

2.5 Vertical and Horizontal Angle Tilt Correction

(GTS-239N has vertical angle tilt correction only.)

When the tilt sensors are activated, automatic correction of vertical and horizontal angle for mislevelment is displayed.

To ensure a precise angle measurement, tilt sensors must be turned on. The display can also be used to fine level the instrument. If the (TILT OVER) display appears the instrument is out of automatic compensation range and must be leveled manually.

Point the telescope toward the light. Turn the diopter ring and adjust the diopter so that the cross hairs are clearly observed.

(Turn the diopter ring toward you first and then backward to focus.)

Aim the target at the peak of the triangle mark of the sighting collimator. Allow a certain space between the sighting collimator and yourself for collimating.

Focus the target with the focusing knob.

*If parallax is created between the cross hairs and the target when viewing vertically or horizontally while looking into the telescope, focusing is incorrect or diopter adjustment is poor. This adversely affects precision in measurement or survey

Eliminate the parallax by carefully focusing and using diopter adjustment.

7 DATA COLLECTION

The GTS-230N series are able to store the measured data into the internal memory.

The internal memory is shared by the measured data files and the coordinate data files.

Maximum 30 files can be generated.

● Measured data

The collected data is memorized into a files.

● The number of measurement points

( In case not using the internal memory in layout mode)

MAX. 24,000 points

Because the internal memory covers both data collection mode and layout mode, the number of measurement points will be decreased when the layout mode is used.

For the internal memory, refer to Chapter 9 “MEMORY MANAGER MODE”.

1) When turning off the power, ensure that you are in the main menu screen or main angle measurement mode.

This ensures completion of the memory access process and avoids possible damage to the stored data.

2) It is recommended for safety to charge the battery (BT-52QA) beforehand and prepare fully charged spare batteries.

7.3.4 Column Offset Measurement

If it is possible to measure circumscription point (P1) of column directly, the distance to the center of the column (P0), coordinate and direction angle can be calculated by measured circumscription points (P2) and (P3).

The direction angle of the center of the column is 1/2 of total direction angle of circumscription points

(P2) and (P3).

7.4 NEZ Auto Calculation

As measured data is collected, coordinates are calculated and stored for traverse or topo collection.

Automatic making out function of coordinate data sets up in CONFIG of data collect. Refer to Section

7.6 “Setting Parameter of Data Collect [CONFIG.]”.

As a default, coordinate data calculated will be saved in a file of the same name as the measurement data file.

When the coordinate data file of the same name as the measurement data file does not exist, it will be generated automatically.

It is possible to change a file for saving coordinate data in the DATA COLLECT Menu 2/2 (F1:SELECT

A FILE).

To calculate a coordinate data, it is necessary to add a point number in Data Collect execution.

When a coordinate data of the same point number exist already, it can be replaced with the new data by confirming display.

●

Coordinates will be calculated using the grid factor.

To set the grid factor, see Section 6.2“Setting the GRID FACTOR” .

LAYOUT mode has two functions which are setting of layout points and setting new points using coordinate data in the internal memory.

Also, if the coordinate data is not stored in the internal memory, this can be input from key board.

The coordinate data is loaded from PC to the internal memory via RS-232C.

●

The coordinate data

The coordinate data is memorized into a file.

For the internal memory, refer to Chapter 9 “MEMORY MANAGER MODE”.

The GTS-230N series are able to store the coordinate data into the internal memory.

The internal memory is shared by the measured data and the coordinate data for layout.

Maximum 30 files can be generated.

●

The number of coordinate data

( In case not using the internal memory in the data collect mode)

MAX. 24,000 points

Because the internal memory covers both data collection mode and layout mode, the number of coordinate data will be decreased when the data collection mode is used.

1) When turning off the power, ensure that you are in the main menu screen or main angle measurement mode.

This ensures completion of the memory access process and avoids possible damage to the stored data.

2) It is recommended for safety to charge the battery (BT-52QA) beforehand and prepare fully charged spare batteries.

3) When recording new point data, remember to consider the amount of internal memory available.

Set up the instrument at a new point, and calculate the coordinate of the new point using the coordinate data of maximum seven known points and the measurements made to these points.

By following observation, resection is possible.

• Resection by distance measurement:2 or more points must be measured

• Resection by angle measurement only:3 or more points must be measured

An occupied point coordinate value will be calculated by the method of least squares.

(In case that 3 known points are measured by angle measurement only, the value would not be calculated by the method of least squares. )

17 CHECK AND ADJUSTMENT

17 CHECK AND ADJUSTMENT

17.1 Checking and adjusting of instrument constant

Normally, the instrument constant does not have discrepancy. It is recommended you measure and compare with an accurately measured distance at a location where the precision is specifically monitored on a consistent basis. If such a location is not available, establish your own base line over

20m (when purchasing the instrument) and compare the data measured with the newly purchased instrument.

In both cases note that the setup displacement of the instrument position over the point, the prism, baseline precision, poor collimation, atmospheric correction, and correction for refraction and earth curvature determine the inspection precision. Please keep in mind these points.

Also, when providing a base line in a building, please note that differences in temperature greatly affect the length measured.

If a difference of 5mm or over is the result from the comparative measurement, the following procedure as shown below could be used to change the instrument constant.

1) Provide point C on a straight line, connecting straight line AB which is almost level and about 100m long. Measure straight lines AB, AC and BC.

A

B

C

2) Obtain the instrument constant by repeating 1) above several times.

Instrument constant = AC+BC–AB

3) When there is error between written instrument constant value and calculated value, review

Section 17.4 “How to Set the Instrument Constant Value”

4) Once again, measure at a calibrated baseline and compare results.

5) If using above procedure and no difference is found from the instrument constant at the factory or a difference of over 5mm is found, contact TOPCON or your TOPCON dealer.

Note: The seal with which the value is written is stuck on the lower part of the instrument, or the battery removal side of the instrument.

17-1


17.2 Checking the Optical Axis

To check if the optical axis of EDM and theodolite are matched, follow the procedure below. It is especially important to check after adjustment of the eyepiece reticle is carried out.

1) Position the Instrument and prism with about 2m apart and face them at each other.

(At this time, the power is ON. )

Prism about 2m

2) Sight through the eyepiece and focus to the prism. Then center the prism on the cross hairs.

Prism

3) Set to the measure mode to distance measurement or set audio.

4) Sight through the eyepiece and focus the (blinking) red light spot by turning the focusing knob in the direction of infinity (clockwise). If displacement of the reticle cross hairs is within one-fifth of the diameter of the round red light spot both vertically and horizontally, adjustment will not be required.

Note: If displacement is more than one-fifth in the above case, and still remains so after rechecking the original line of sight, the instrument must be adjusted by competent technicians. Please contact TOPCON or your TOPCON dealer to adjust the instrument.

17.3 Checking/Adjusting the Theodolite Functions

● Pointers on the Adjustment

1) Adjust the eyepiece of the telescope properly prior to any checking operation which involves sighting through the telescope.

Remember to focus properly, with parallax completely eliminated.

2) Carry out the adjustments in the order of item numbers, as the adjustments are dependent one upon another. Adjustments carried out in the wrong sequence may even nullify previous adjustment.

3) Always conclude adjustments by tightening the adjustment screws securely (but do not tighten them more than necessary, as you may strip the threads, twist off the screw or place undue stress on the parts).

Furthermore, always tighten by revolving in the direction of tightening tension.

4) The attachment screws must also be tightened sufficiently, upon completion of adjustments.

5) Always repeat checking operations after adjustments are made, in order to confirm results.

● Notes on the Tribrach

Note that the angle measuring precision may be effected directly if the tribrach has not been installed firmly.

1) If any leveling screw becomes loose and slack or if collimation is unstable due to the looseness of leveling screws, adjust by tightening the adjusting screws (in 2 places) installed over each leveling screw with a screwdriver

2) If there is any slack between the leveling screws and the base, loosen the set screw of the holding ring and tighten the holding ring with adjusting pin, until it is properly adjusted. Re-tighten the set screw on completing the adjustment.

17.3.1Checking /Adjusting the Plate Level

Adjustment is required if the axis of the plate level is not perpendicular to the vertical axis.

● Check

1) Place the plate level parallel to a line running through the centers of two leveling screws, say, A and

B. Use these two leveling screws only and place the bubble in the center of the plate level.

2) Rotate the instrument 180° or 200g around the vertical axis and check bubble movement of the plate level. If the bubble has been displaced, then proceed with the following adjustment.

Plate level

Leveling screw A

Leveling screw B

● Adjustment

1) Adjust the level adjustment capstan screw, with the accessory adjusting pin and return the bubble towards the center of the plate level. Correct only one-half of the displacement by this method.

2) Correct the remaining amount of the bubble displacement with the leveling screws.

3) Rotate the instrument 180° or 200g around the vertical axis once more and check bubble movement. If the bubble is still displaced, then repeat the adjustment.

Level adjustment capstan screw

Half amount of displacement

17.3.2Checking /Adjusting the Circular Level

Adjustment is required if the axis of the circular level is also not perpendicular to the vertical axis.

● Check

1) Carefully level the instrument with the plate level only. If the bubble of the circular level is centered properly, adjustment is not required. Otherwise, proceed with the following adjustment.

● Adjustment

1) Shift the bubble to the center of the circular level, by adjusting three capstan adjustment screws on the bottom surface of the circular level, with the accessory adjusting pin.

17.3.3Adjustment of the Vertical Cross-hair

Adjustment is required if the vertical cross-hair is not in a place perpendicular to the horizontal axis of the telescope ( since it must be possible to use any point on the hair for measuring horizontal angles or running lines).

● Check

1) Set the instrument up the tripod and carefully level it.

2) Sight the cross-hairs on a well defined Point A at a distance of, at least, 50 meters (160ft.) and clamp horizontal motion.

3) Next swing the telescope vertically using the vertical tangent screw, and check whether the point travels along the length of the vertical cross-hair.

4) If the point appears to move continuously on the hair, the vertical cross-hair lies in a plane perpendicular to the horizontal axis ( and adjustment is not required ).

5) However, if the point appears to be displaced from the vertical cross-hair, as the telescope is swung vertically, then proceed with the following adjustment.

● Adjustment

1) Unscrew the cross-hair adjustment section cover, by revolving it in the counterclockwise direction, and take it off. This will expose four eyepiece section attachment screws.

Eyepiece section attachment screws

2) Loosen all four attachment screws slightly with the accessory screw-drive (while taking note of the number of revolutions).

Then revolve the eyepiece section so that the vertical cross-hair coincides to Point A’.

Finally, re-tighten the four screws by the amount that they were loosened.

3) Check once more and if the point travels the entire length of the vertical cross-hair, further adjustment is not required.

Note: Perform following adjustment after completing the above adjustment .

Section 17.3.4 “Collimation of the Instrument”, Section 17.3.6 “Adjustment of Vertical Angle 0

Datum”.

17-5


17.3.4Collimation of the Instrument

Collimation is required to make the line of sight of the telescope perpendicular to the horizontal axis of the instrument, otherwise, it will not be possible to extend a straight line by direct means.

● Check

1) Set the instrument up with clear

Eyepiece sights of about 50 to 60meters

(160 to 200 ft.) on both sides of the instrument.

2) Level the instrument properly with the

50ｍ

plate level.

3) Sight Point A at approximately 50 meters (160 ft.) distance.

Telescope

4) Loosen the vertical motion clamp only, and rotate the telescope 180° or

200g around the horizontal axis, so that the telescope is pointed in the opposite direction.

5) Sight Point B, at equal distance as

Point A and tighten the vertical motion clamp.

50ｍ

6) Loosen the horizontal motion clamp and rotate the instrument 180° or

200g around the vertical axis. Fix a sight on Point A once more and tighten the horizontal motion clamp.

50ｍ

7) Loosen the vertical motion clamp only and rotate the telescope 180° or 200g around the horizontal axis once more and fix a sight on Point C, which should coincide with previous

Point B.

8) If Points B and C do not coincide, adjust in the following manner.

50ｍ

● Adjustment

1) Unscrew the cross-hair adjustment section cover.

2) Find Point D at a point between Points C and B, which should be equal to 1/4th the distance between Points B and C and measured from Point C. This is because the apparent error between Points B and C is four times the actual error since the telescope has been reversed twice during the checking operation.

3) Shift the vertical cross-hair line and coincide it with

Point D, by revolving the left and right capstan adjustment screws with the adjusting pin.Upon completing the adjustment, repeat the checking operation once more.

If Points B and C coincide, further adjustment is not required. Otherwise , repeat the adjustment.

Note: 1 First, loosen the capstan adjustment screw on the side to which the vertical cross-hair line must be moved. Then tighten the adjustment screw on the opposite side by an equal amount which will leave the tension of the adjustment screws unchanged.

Revolve in the counterclockwise direction to loosen and in the clockwise direction to tighten, but revolve as little as possible.

Perform following adjustment after completing above adjustment . Section 17.3.6

“Adjustment of Vertical Angle 0 Datum”, Section 17.2 “Checking the Optical Axis”.

17.3.5Checking / Adjusting the Optical Plummet Telescope

Adjustment is required to make the line of sight of the optical plummet telescope coincide with the vertical axis ( otherwise the vertical axis will not be in the true vertical when the instrument is optically plumbed).

● Check

1) Coincide the center mark and the point. (See Chapter 2 “PREPARATION FOR MEASUREMENT”.)

2) Rotate the instrument 180° or 200g around the vertical axis and check the center mark.

If the point is properly centered in the center mark, adjustment is not required. Otherwise, adjust in the following manner.

● Adjustment

1) Take off the adjustment section cover of the optical plummet telescope eyepiece. This will expose four capstan adjustment screws which should be adjusted with the accessory adjusting pin to shift the center mark to the point. However, correct only one-half of the displacement in this manner.

2) Use the leveling screws and coincide the point and center mark.

3) Rotate the instrument 180° or 200g around the vertical axis once more and check the center mark.

If it is coincided to the point, then further adjustment is not required. Otherwise, repeat the adjustment.

Note: First, loosen the capstan adjustment screw on the side to which the center mark must be moved. Then tighten the adjustment screw on the opposite side by an equal amount which will leave the tension of the adjustment screws unchanged.

Revolve in the counterclockwise direction to loosen and in the clockwise direction to tighten, but revolve as little as possible.

17.3.6Adjustment of Vertical Angle 0 Datum

If when measuring the vertical angle of target A at telescope position normal (direct) and reverse settings, the amount of normal and reverse measurements combined is other than 360° (ZENITH-0), half of the difference from 360° is the error amount from corrected 0 setting. Carry out adjustment. As adjustment for vertical angle 0 setting is the criteria for determining instrument coordinate origin, use special care for adjustment.

18 PRECAUTIONS

18 PRECAUTIONS

1) For transportation, hold by the handle or yoke of the instrument. Never hold by the lens barrel as it can affect the fixing bracket inside and reduce the accuracy of the instrument.

2) Never expose the instrument without a filter to direct sunlight. It may damage the components inside the instrument.

3) Never leave the instrument unprotected in high temperature. The temperature inside instrument may easily reach up to 70°C or above and will reduce the service life.

4) The instrument should be stored in the room temperature range of minus 30°C to plus 60°C.

5) When a high degree of precision is required for measurement, provide shade against direct sunlight for the instrument and tripod.

6) Any sudden change of temperature to the instrument or prism may result in a reduction of measuring distance range, i.e. when taking the instrument out from a heated vehicle.

7) When opening the carrying case and taking out the instrument, place the case horizontally, then open the case.

8) When returning the instrument to its case, be sure to match the white positioning marks provided with the case and place the instrument with the eyepiece upward.

9) For transportation, provide dampening or a cushion appropriately to avoid sudden shock or vibration.

10) For cleaning the instrument after use, remove dust using a cleaning brush, then wipe off with a cloth.

11) For cleaning the lens surface, use a cleaning brush to remove the dust, then use a clean lintless cotton cloth. Moisten it with alcohol ( or mixture with ether ) to wipe gently in a rotational motion from the center out.

12) Even if any abnormality occurs, never attempt to disassemble or lubricate the instrument yourself.

Always consult with TOPCON or your dealer.

13) To remove the dust on the case, never use thinner or benzine. Use a clean cloth moistened with neutral detergent.

14) Check each part of the tripod after extended use. Parts (screws or clamps) may work themselves free.

1 Dual Axis Compensation

Inclination of the vertical axis with respect to true vertical will result in incorrectly measured horizontal angles. The extent of the error in horizontal angle measurement due to axis tilt depends on three factors :

● the amount of the tilt of axis

● the elevation of the target

● the horizontal angle between the direction of till of the vertical axis and the target.

These factors are related by the following formula :

Hz err

= V

• sinα

•

tanh where v = tilt of axis in arcseconds

α = azimuth angle between vert. axis direction and target h = elevation of target

Hz err

= error in horizontal angle

Example: When the vertical axis is tilted by 30 arcseconds, the target is 10° above the horizon and rotated 90 in azimuth from the direction of the vertical axis error.

Hz err

= 30"

•

sinα

•

tan10°

Hz err

= 30"

•

1

•

0

.176326=5.29"

From the above example it can be seen that horizontal angle errors will increase with steeper vertical sights (tangent will increase as vertical angle increases) and will be at a maximum when the target is at right angles (sin 90°=1) to the direction of the vertical axis error. Errors will be at a minimum when the sights are nearly horizontal (h=0, tan0=0) and in the same direction as the vertical axis error (α =0, sin0=0). Please refer to the table below to see the relationship between axis tilt (v) and elevation (h) and the error in horizontal angles which results from these factors.

It is clear from the table that dual axis compensation has the most benefit when the elevation of the target is greater then 30° and the axis is tilted more than 10". The entries indicated in bold in the table show, in fact, that for many common surveying applications i.e. target elevation

<30° and axis error <10", virtually no correction would be required. Dual axis compensation is especially suited then for applications where the sights are very steep.

Even though the compensators can correct horizontal angles for vertical axis errors,

it is still important to use care in setting up the instrument.

Centering error, for instance, cannot be corrected by the compensators. If the vertical axis is tilted by 1’ with the instrument 1.4meters above the ground, a centering error of approx. 0.4mm will result. The maximum effect of this error at 10m is about 8" of horizontal angle error.

In order to maintain the increased accuracy possible through dual axis compensation, it is necessary to keep the compensators in proper adjustment.The compensators must agree with the actual level condition of the instrument. Through various environmental stresses, the agreement between the level condition sensed by the compensators and the true level condition of the instrument may be disturbed. In order to reestablish the correct relationship between the compensator and the true level condition of the instrument, it is necessary to carry out the

vertical indexing procedure listed on chapter 17.3.6 "Adjustment of Vertical Angle 0 Datum". This

adjustment will both reset the vertical index (cause a direct + indirect zenith reading to the same elevation to equal 360°) and zero the level reference for the horizontal compensator. While correct vertical angles can be obtained by averaging direct and indirect reading even when the index is improperly adjusted, the same is not true for horizontal angles. Since the vertical axis error is fixed for a given setup, its effect cannot be removed by averaging two readings.

For this reason, it is extremely important to maintain the vertical indexing adjustment to insure proper correction of the horizontal angles.

2 Precaution when Charging or Storing Batteries

The capacity of battery will be affected and its service life shortened in any of the following cases while it is recharged, dischrged or stored.

1) Recharging

Fig. 1 shows how ambient temperature at recharging is related to charging efficiency or as affecting discharge capacity. As seen from the figure, charging at normal temperature is best, and the efficiency decreases as the temperature rises. It is best, therefore, to always recharge the battery at normal temperature to obtain full use of battery capacity and enjoy maximum operation per charge.

And the service life of your battery will be shortened if it is frequently overcharged or recharged at high temperature.

Note: 0.1C charge means that the battery is recharged with 0.1 -time current as against its capacity.

2) Discharge

Fig. 2 shows discharge temperature characteristics. Discharge characteristics at high temperature are the same as those at normal temperatures. The battery is likely to have reduced discharge capacity as well as lower discharged voltage when discharged at low temperature. And the service life of your battery will be shortened if it is greatly overcharged.

Note: 1C discharge means one with 1 -time current over battery capacity.

3) Storage

See Fig. 3 for how storing period at different temperature levels is related to the remaining capacity.

The battery will lose its capacity as storage temperature rises and the storage period increases.

This does not mean, however , that the battery performance is damaged when the battery is stored.

The battery, reduced in capacity, will be restored once it is recharged. Always recharge your battery before use. And recharge and discharge the battery 3 or 4 times to restore its capacity if it has been stored for a long period or at high temperature. Storing at high temperature can adversely affect the service life of your battery.

Your battery has been fully charged before leaving the factory, but its capacity may be affected considerably when it takes several months to reach you, if it is stored at high temperature area or passes through a high-temperature region. Then, the battery must be recharged and discharged

3~4 times to fully restore its capacity.

And the battery should always be stored at normal temperature or lower if it will not be used for any long period. This helps your battery have a longer service life.
