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 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.
External power source
Use only recommended batteries or external power source. Use of batteries or an external
power source not recommended by us may result in equipment failure.
(For further information see the chapter 'BATTERY SYSTEM.')
Noise from the inside of instrument
When EDM turns on, the sound of motors from inside the instrument body may be
heard. This is normal and does not effect operation of the instrument.

z Lighting, Blinking, and Extinguishing of Laser Pointer
Whenever the [F3] (L.P.) key is pressed, the laser pointer will light up, blink, or be extinguished, in
that order. The laser pointer assists with collimation by radiating visible laser light from the objective
lens to the target.
Laser aperture
z The laser pointer indicates the approximate collimation position of the telescope. It does
not indicate the exact collimation position. To adjust the laser pointer, see 17.2.2
“Checking the optical axis of Laser pointer”.
z When the EDM is working, the laser pointer will blink.
z You cannot see the laser pointer when looking through the telescope. Therefore, please
look directly, with the naked eye, at the point indicated by the laser pointer.
z The distance to which the laser pointer can be used will vary with climatic conditions and
with the eyesight of the user.
z When the laser pointer is used, the operating time of internal power source will become
short.

z Tilt correction
The tilt setting mode performed here will not be memorized after powering OFF. To set TILT
correction in the initialized setting (it is memorized after powering OFF), see Section 6.4.3 “Vertical
and Horizontal Angle Tilt correction (Tilt ON/OFF)”.
z Point guide
Fast and simple to use, the Point Guide feature is useful when doing stake out work. The Point
Guide System on the instrument telescope assist the rod person to get on-line. When using with the
Point Guide System, the operating time of internal power source will become short.
Turning the Point Guide ON and Operation:
Press the [F3] key to turn ON the Point Guide.
Looking at the objective lens of the telescope, the right
LED will blink and the left LED will stay lit.
Instrument
The Point Guide should be used within a distance of 100
meters (328 feet). The quality of its results will depend on
the weather conditions and the user’s eyesight.
The goal of the rod person is to look at both LED’s on the
instrument and move the prism on-line until both LED’s
are equally bright.
If the solid LED is brighter, move right.
If the blinking LED is brighter, move left.
Illuminate

2 PREPARATION FOR MEASUREMENT
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

Repeat the procedures 1 and 2 for each 90°
(100gon) rotation of the instrument and check
whether the bubble is correctly centered for all
four points.
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.

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.

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.
For general usage of the battery, see Chapter 14 “POWER SOURCE AND CHARGING”.
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
(GPT-3107N 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.

You can select measurement mode between Prism mode which collimating a prism and Non-prism
mode that is collimating a target object except prism.
z Regardless of whether the laser pointer is used, measurement is possible with both the non-prism
mode and the prism mode. That is, when the GPT-3100N is used in the open air, in an urban area,
etc., the laser pointer can be stopped and distance measurement then conducted, making it
possible to prevent the laser light from hitting a third party.
z When using a reflection sheet, measure with the prism mode.
z For measurement with a prism, be sure to measure with the prism mode. If you measure with the
non-prism mode, accuracy cannot be guaranteed.
z Non-prism mode enables all distance measurements such Distance measurement, Coordinate
measurement, Offset measurement and Layout.

6.2 Setting the GRID FACTOR
GRID FACTOR can reset in this menu mode.
For more information, refer to Section 8.1.1 “Setting the GRID FACTOR”.
Grid Factor can be applied to the following application programs.
It is also possible to cancel the Grid factor function by selecting "DON'T USE" in “SELECTING MODE”.
At this time the setting and selecting screens for Grid Factor will be omitted.
z Data collection mode
When the NEZ automatic calculation (NEZ AUTO. CALC) is ON, Grid factor will be applied to the
coordinate data (Including PTL data) recorded into a coordinate data file when the RAW data is
measured and recorded. (In this case, Grid Factor is not applied to the RAW data recorded into the
measured data file.)
PTL (Point To Line measurement)
When executing PTL measurement mode, the NEZ Auto Calculation wil be turned on compulsorily and
Grid factor will be applied to the coordinate data.
z Layout
Execution Layout (Including PTL measurement mode)
1. When displaying the difference (dHD) between grid horizontal distance to a layout point (HDg) on
the projection plane and measured ground horizontal distance to a prism point (HD), Grid factor will be
applied to grid distance (HDg) in order to reverse-convert grid distance to ground distance.
2. After completion of a layout point, the displayed coordinate data will be applied to grid factor in order
to compare with surveying data and calculated data on the projection plane.
(NEW POINT-Side Shot)
In side shot method, a new point coordinate data will be applied to grid factor and the new point
coordinate data will be recorded into a coordinate data file.
(NEW POINT - Resection)
In resection method, when a new point calculated coordinate data is displayed or recorded, the new
point coordinate data will be applied to grid factor and the coordinate data will be recorded into a
coordinate data file.
z MLM (Missing Line Measurement)
When selecting grid factor "USE G.F.", measured data will be applied to grid factor. At this time,
horizontal distance (dHD) and slope distance (dSD) will be on the projection plane.
z AREA (Area calculation / Measured method)
When selecting grid factor "USE G.F.", measured data will be applied to grid factor. At this time, the
calculated area will be on the projection plane.
Note: Calculation of Z coordinate is not influenced even if it is applied to grid factor.

DATA COLLECTION
The GPT-3100N is 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.
z Measured data
The collected data is memorized into a files.
z 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 Data Collect Offset Measurement mode
This mode is useful when it is difficult to set up the prism directly, for example at the center of a tree.
Data Collect . Offset Measurement has two measuring methods.
z Angle offset measurement
z Distance offset measurement
z Plane offset measurement
z Column offset measurement
7.3.1 Angle Offset Measurement
Place the prism at the same horizontal distance from the instrument as that of point A0 to measure.
When measuring coordinates of ground point A1 :Set the
instrument height / prism height.
When measuring coordinates of point A0 : Set the
instrument height only. (Set the prism height to 0 ).
Prism P
When sighting to A0, you can select one of two
ways. One is to fix vertical angle to the prism
position even up down the telescope position, and
the other is to gear vertical angle to the up down
of telescope movement. In case following the
vertical angle to the movement of telescope, SD
(Slope Distance) and VD (Vertical Distance) will
be changed according to the movement of
telescope.
To set this option, refer to Chapter 16

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
7.7 “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.
z Coordinates will be calculated using the grid factor.
To set the grid factor, see Section 6.2 “Setting the GRID FACTOR”.

LAYOUT
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 keyboard.
The coordinate data is loaded from PC to the internal memory via RS-232C.
z The coordinate data
The coordinate data is memorized into a file.
For the internal memory, refer to Chapter 9 “MEMORY MANAGER MODE”.
The GPT-3100N is 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.
z 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.

8.3.2 Resection Method
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. )

K =0.14 or 0.2.......... Coefficient of
refraction
R =6372km.............. Radius of earth
α (or β)................... Altitude angle
L .............................. Slope distance
z The conversion formula for horizontal and vertical distances is as follows when correction for
refraction and earth curvature is not applied.
D=L•cosα
Z=L•sinα
Note: The coefficient of the instrument has been set at 0.14 before shipment (K=0.14).

CHECK AND ADJUSTMENT
17.1 Checking and adjusting of instrument constant
Note: Each of the Prism mode and Non-prism mode has instrument constant.
Check and adjust in both non-prism and prism modes to obtain an instrument constant for
each.
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 with the data measured with 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 the difference in temperature greatly
changes the length measured in the building.
If the difference between the measured length of the baseline and the actual length exceeds the range
of the nominal accuracy, change the instrument constant of the prism mode according to the following
procedure.
1) On a basically horizontal line of about 100 meters, line AB, establish point C. Measure each
distance, AB, AC and BC, about 10 times, and calculate the average value for each.
A
B
C
2) Repeat Step 1 several times. Then calculate the variance with the current instrument constant (ΔK).
ΔK = AB - (AC + BC)
3) Calculate the new instrument constant according to the formula below. Then reset the instrument
constant according to Section 17.4 “How to Set the Instrument Constant Value”.
New instrument constant = current instrument constant + ΔK
4) Once again, measure the baseline and compare the results to the baseline’s actual length.
Repeat the same procedure in non-prism mode as well.
5) If the results of the measurement conducted in Step 4 exceed the range of the nominal accuracy,
contact TOPCON or your TOPCON dealer.

17.2.2Checking the optical axis of Laser pointer
Check whether the optical axis of the laser pointer coincides with the optical axis of the telescope by
carrying out the following steps.
The laser pointer indicates the approximate collimation position of the telescope. It does not indicate
the exact collimation position.
Therefore, it is not failure of the GPT-3100N although it may shift to 6mm by the optical axis and laser
point on the target about 10 meters from the GPT-3100N.
1) On the center of a piece of graph paper or white paper, draw a target in the form of a vertical line
and an intersecting horizontal line.
2) Set up the target about 10 meters from the GPT-3100N, and collimate the GPT-3100N to the point
of intersection of the two lines.
3) Turn on power to the GPT-3100N, press the star key mode, and then press the L. P. key, lighting up
the laser pointer.

About10m
z Checking of laser pointer's optical axis
4) With the GPT-3100N collimated to the point of intersection of the two lines, check whether the
center of the laser pointer is within about 6 mm of the point of intersection.
Note: If you look through the telescope at this time, you will not be able to see the laser pointer.
Therefore, conduct this check with the naked eye, viewing the target and the laser pointer
from the side of, or from above, the GPT-3100N.
5) If the center of the laser pointer is within about 6 mm of the point of intersection, there will be no
problems with using the GPT-3100N. If the distance is greater than 6 mm, carry out the following
steps to align the center of the laser pointer with the point of intersection, and to align the laser
pointer's optical axis with that of the telescope.
z Adjusting the laser pointer's optical axis
6) As shown in the drawing, remove the 3 rubber caps on top of the instrument, revealing the
adjustment screws.
7) Using the accessory hexagonal wrench, adjust each of the screws - A, B and C - thereby moving

z 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.
z 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.

running lines).
z 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.
z 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.

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 fit it correctly into the concave shape inside the case.
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.

APPENDIX

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 :
z the amount of the tilt of axis
z the elevation of the target
z the horizontal angle between the direction of till of the vertical axis and the target.
These factors are related by the following formula :
Hzerr = V•sinα • tanh
where v = tilt of axis in arcseconds
α = azimuth angle between vert. axis direction and target
h = elevation of target
Hzerr = 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.
Hzerr = 30" • sinα • tan10°
Hzerr = 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.

APPENDIX-1
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 14.3.6 "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.

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, discharged 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.
