Module Replacement Criteria
•
If the lowest voltage battery is 0.1 less than the second lowest voltage battery, replace the lowest voltage
battery module.
•
If the second lowest voltage battery is more than 0.08-volts less than the third lowest voltage battery, replace
the second lowest voltage battery.
•
Prior to replacing the module, verify the serviceability of the battery's sense lead (measure for resistance of
30.9 K ohms), and verify the module's voltage reading with a DVOM.
Sense Lead Criteria
•
If two adjoining modules are indicating incorrectly, the sense lead should be suspected and its resistance
should be measured.
•
Resistance specification is 30.9 K ohms.
