200 x 1.25 = 250 minutes or 4 Hours & 10 minutes
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 bat-
tery 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 calcu-
lated 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 constant, 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 example add 50 min-
utes to the 3 hour and 20 minutes for a total recharge time of 4
hour and 10 minutes.
