CHARGE PERIOD
The approximate time required to bring a battery to a full charge
state depends upon the number of ampere hours (AH’s) de-
pleted from the battery. AH’s are determined by multiplying the
number of hours times the number of amps supplied by a
battery to a load. For example - if a load was connected to a
battery which drew 10 Amps for a period of 5 hours, the battery
will have supplied 50 AH’s. The approximate recharge time
required to restore the 50 AH’s depleted from the battery would
be calculated by dividing 50 AH’s by the selected charge rate. If
the 15 Amp charge rate is chosen then divide 50 AH’s by 15
Amps, this equal to 3.3 hours or 3 hour and 20 minutes. During
the charge cycle, the 15 Amp charge rate will not remain con-
stant, rather as the battery charges it will taper to approximately
6-7 Amps. Also not all of the energy going into the battery is
directly converted, some is lost in the form of heat. For these
reasons allow an additional 25% in charge time. For this ex-
ample add 50 minutes to the 3 hour and 20 minutes for a total
recharge time of 4 hour and 10 minutes.
