prediction algorithm.
The Reserve & Recharge Time Calculator can solve for hours of
reserve, total effective reserve in amp-hours, hours to 95% recharge of
the batteries and rectifier recharge factor. Enter new values for office
temperature, end cell voltage, plant load, rectifier capacity or battery
strings and hit enter to update the calculations. Calculations are
