Exide Technologies GB4158 - Manual (Page 4)

The Tubular-LM FP charging algorithm includes an unterminated Float Stage that begins automatically
once full charge is complete. The Float Stage holds the battery at 2.28 volts per cell (VPC) until the
battery is required for service. The result is that the battery is maintained at full state of charge which
helps to prevent self-discharge and sulfation.
WHEN IT IS TIME TO PUT THE BATTERY INTO SERVICE, REMOVE THE BATTERY FROM
THE CHARGER BY UNPLUGGING THE CHARGER POWER CORD FROM THE POWER
OUTLET AND THEN DISCONNECT THE CHARGER CABLE FROM THE BATTERY CABLE.
High “on charge” temperatures or frequent need for water additions are indications of overcharging.
Short running times and/or low end-of-charge specific gravities may indicate inadequate recharge.
Consult your local GNB Industrial Power representative on specific charging problems.
If the charger does not work correctly or if it has been damaged, unplug it immediately from the power
outlet and contact your local GNB Industrial Power service representative.
The charger may be provided with a thermal sensor connected to the top of the battery. With this
sensor, the charging profile will automatically compensate for variable battery temperatures. Do not
disconnect the sensor from the top of the battery or the charger.
The charger is equipped with a two-tone audible alarm. In the event of an alarm condition, the audible
alarm will sound and the LED indicator will flash. Possible alarm conditions are:
When there is an alarm, the charger stops supplying current to the battery.
