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.
