**In float charging battery is charged with the same rate
as it is discharged.It is used when battery rarely gets
discharged.It requires charging the battery at reduced
voltage to avoid the battery from overcharging.

of time to charge the battery. It is used when battery is
discharged heavily, it enables quick charging of batteries.
