Battery Over Voltage: Charger’s Output DC Cable
connection is possibly connected to a battery pack
with voltage higher than the output rating of the
charger.
Battery Temperature Low / High: If an external ther-
mistor is connected in the application, the charger has
detected an attempt to use the battery out of its rec-
ommended temperature range… thaw the battery if
cold or cease charging and allow battery to cool down
before attempting to restart charge.
Battery Pack Unbalanced - V: Caused by unbal-
anced battery condition and or excessive battery plate
sulphation during Bulk Constant Current Stage. Ex-
ample: some batteries are at a much higher state of
charge than others. This may require replacement of
the batteries. Refer to the Equipment’s Operators
manual for instructions on servicing the battery pack.
Battery Pack Unbalanced - A: Caused by an unbal-
anced battery condition during Absorption Constant
Voltage Stage. Inspect each battery with a load tester
as well as observe if any battery is ‘hotter’ to the
touch than other batteries in the pack. The indication
is that a cell(s) within the pack may have shorted, or
experienced stratification of the electrolyte (over-
charging due to incorrect MODE setting) and may re-
quire replacement of the batteries. Refer to the Equip-
ment’s Operators manual for instructions on servicing
the battery pack.
Batt Is 100% Discharged: Based on 1.75Vdc / cell,
this error is produced when cell voltage falls below
this value (example: 21Vdc for 24V Battery Pack).
A.C. Power should be connected to charger and
charging initiated immediately.
Batt Emergency Under-Voltage: Based on 1.31Vdc/
cell, battery may have been subjected to an extended
Over-Discharge condition (example: 15.75Vdc for a
24V Battery Pack) and battery is in danger of becom-
ing damaged beyond probable repair. Using a voltme-
ter check if battery voltage is well under its 100%
depth of charge. Remove all loads from battery, in-
cluding charger and allow time for battery pack to
‘spring’ back to above 1.31V/cell. Reconnect only the
charger to battery pack and allow to charge.
Batt Beyond Over Discharged: Based on 1Vdc/cell,
battery may have been subjected to an extreme Over-
Discharge condition (example: 12Vdc for a 24V Bat-
tery Pack) and battery damage is beyond probable re-
pair – expect a shortened life span for battery. Charge
will have turned off completely, to avoid adding to the
decaying process. Using a voltmeter check if battery
voltage is well under its 100% depth of charge. Re-
move all loads from battery, including charger and al-
low time for battery pack to ‘spring’ back to above
1Vdc/cell. Reconnect only the charger to battery pack
and allow to charge.
