Float Charge

The float charge is a maintenance mode in which the output
voltage of the charger is reduced to a lower level, typically
about 13.5 volts to maintain the battery’s charge without
losing electrolyte through gassing. In the float mode, the
charger will initiate a new charge cycle under any of these
conditions:

AC power is disconnected and reconnected

current demand on charger exceeds the battery recharge
current setting

The chart in Figure B-1 shows the three-stage charging
profile.
