CHARGING

Cycle Applications: Apply constant voltage charge at

2.35v/c – 2.45v/c (14.1 – 14.7v for 12v Monobloc) at 20°C.

Initial charging current should be set at less than 0.25C

Amps. Switch to float charge to avoid overcharging.

“Float” or “Stand-By” Service: Apply constant voltage

charge of 2.25v/c – 2.30v/c (13.5 to 13.8 volts for 12v

Monobloc at 20°C. When held at this voltage, the battery

will seek its own current level and maintain itself in a fully

charged condition.

Temperature Compensation: Charging Voltage for both

Cyclic and Standby applications should be regulated in

relation to ambient temperature. As temperature rises

charging voltage should be reduced to prevent overcharge

and increased as temperature falls to avoid undercharge.

For further charging information including temperature

compensation factors, see Power Sonic Technical Manual/

Power Sonic Charger specifications.
