Online battery charge time calculator to calculate the estimated charging time of a rechargeable lead acid battery.
Battery charging methods are usually separated into two general categories:
(i). Fast charge is typically a system that can recharge a battery in about one or two hours, while slow charge usually refers to an overnight recharge (or longer).
(ii). Slow charge is usually defined as a charging current that can be applied to the battery indefinitely without damaging the cell (this method is sometimes referred to as a trickle charging).
Formula:
T = BC ÷ I
where,BC = battery capacity
I = charging Current
T = battery charge time
