Simplified formulae for a battery cell discharge and recharge are: ... There are basically two methods of charging lead-acid batteries and these are constant current ...
CHARGING 2 OR MORE BATTERIES IN SERIES. Lead acid batteries are strings of 2 volt cells connected in series, commonly 2, 3, 4 or 6 cells per battery. Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently.
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.

Charging a lead-acid battery. Charging is the reverse process. A battery charger sends the negatively charged electrons to the negative battery plates which then flow through the battery to the positive plates. The resulting chemical change again creates a difference in potential between the positive and negative plates, ie. a voltage. In this ...
Lead acid batteries are strings of 2 volt cells connected in series, commonly 2, 3, 4 or 6 cells per battery. Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently. However, as the number of batteries in series increases, so does the possibility of slight differences in capacity.
During charging, the lead-acid battery undergoes a reverse chemical reaction that converts the lead sulfate on the electrodes back into lead and lead dioxide, and the sulfuric acid is replenished. This process is known as "recharging" and it restores the battery''s capacity to store electrical energy.
Going Further … I already rigged up an improved SLA battery charger to charge my 12V/7Ah SLA battery with an 18V laptop AC/DC adaptor. The charger circuitry, however, only implements the constant current stage of the standard lead-acid battery charge curve, since that is when most of a battery''s capacity is refilled and is much simpler to build than one with a …
