Battery Health (Deterioration) Judgment
To judge Battery Deterioration, measure and manage the internal resistance of the
battery being installed or new replacement battery periodically.
In general, internal resistance value increased by 1.5 ~ 2 times from initial value
(reference value) when battery is deteriorated
[Judgment of Health (Deterioration) ]
 In case Lead Storage Cell (Lead-Acid battery), Warning status starts when
internal resistance value increased by 1.5 from initial internal resistance value.
Deterioration standard is little different by manufacturer of Battery
 Even though Same Capacity battery, Initial Internal Resistance value of Battery is
different from Type and manufacturer.
 “WARNING”, “FAIL” level of Internal Resistance is little different by manufacturer.
[Recommendation of Battery Replacement Time]
Periodically measure Impedance, Voltages and Temperature of the battery.
In management and save the measurement data which recommends the Time of
Battery Replacement.
[Judgment of Battery Replacement Time]
 Based on the specifications of the battery in management when installed,

Do not over
Capacity
Battery at Impedance
DC 300V Input when measure Voltage at
measurement range . This is to protect from Electric Shock
 Do not measure AC Voltage
[Caution]
 Do not Input exceeding Maximum Voltage, Currents of each measuring range.
Exceeding Input may cause damage to the Analyzer.
 When measure Low Voltage Battery after measure High Voltage Battery, residue in
Analyzer may damage Low Voltage Battery. Be sure to measure safely after
discharge on DC Condenser inside of Analyzer by shorting the Test Probe.
[Note]
 Internal Resistance of Battery being measured can be different from Current Flow
status and Discharge status. To support accuracy and reliability of judgment, be
sure to measure at following condition.
 Lead Storage battery has big resistance on electrodes. Resistance can be
different between the area of electrode toward Case and the area of End of
Electrode. Contact area between Electrode and Test Probe should be consistent.

Impedance (Internal Resistance) and Voltage

Battery Reference Value (Example): 4mΩ, 1.6V.

Standard to judge on Battery Deterioration.

Impedance :
 [WARNING] 6mΩ(1.5 times increased from Initial data: 4mΩ).
 [FAIL] 8mΩ(2 times increased from Initial data: 4mΩ).
 Voltage :
 [WARNING] 1.44V (90% of Initial data: 1.6V).
[Standard to judge on Battery Deterioration]
 Battery deterioration can be judged from Impedance. Impedance value usually
increased by 1.5 ~ 2 times from Initial Data from new or good battery. There is

than Upper 2 Level Max limit. If Voltage measured simultaneously is higher or
lower than Minimum Limit, both case “Warning” light on with Beeper sound.
 Measured value of Resistance is higher than Upper 2 Level Max Limit. If Voltage
measured simultaneously is higher or lower than Minimum Limit, both case
“Warning” light on with Beeper sound.
 Any of Resistance or Voltages exceeds Limit, “Warning”or “Fail” message appear.

③ Pull in Tip and separate Tip.
④ Assembly Tip and Test Probe in accordance with reverse steps as above.
⑤ Check whether Measurement with New Tip is no problem and accurate.
To prevent any damage from contact , make sure the cable is tightly connected
And no move when pull in or rotate the cable.
99
13.6 Cleaning
Use soft fabrics to clean lightly dust with wet with water or detergent. Never use
Benzene, alcohol, acetone, ether etc which may change color.
13.7 Scrap
[Warning]
When scrap unit, separate Battery which disposal should be in accordance of rule.
To avoid electric shock, Power off and separate battery after Test Probe
disconnected.
