DESIGN FLOAT LIFE

The float life of the battery is defined in calendar years at a standard temperature of 25°C, when floated with a charge voltage of 2.25 volts per cell.The expected float life of batteries at various average ambient temperatures, when floated with a voltage of 2.25 volts per cell is shown in graph.

DISCHARGE CHARACTERISTICS

The curves in the figure illustrate the typical discharge characteristics at an ambient temperature of 25°C. The C20 expresses the nominal capacity of the battery at 20 hr discharge rate.

CYCLE LIFE

Battery cycle life is highly dependent on the depth of discharge, recharge and ambient temperature that the battery experiences during each cycle. The number of cycles related to the depth of discharge with respect to % capacity is shown in graph.
