Battery Chargers

How do battery chargers work?
Please be specific, and it'd be great if you could list were you found the information. Thanks!
A Secondary Cell is an Electrolytic cell used to store electricity. Once discharged it may be restored by recharging i.e. by putting current through the cell in the direction opposite to that of discharge current.
This is done by applying a voltage to the cell higher than the o/c terminal voltage. This causes the current through the cell to be reversed from the normal discharge current.
A cell is charged when all the available material in the plates is re-converted to the original material. There are various indicators when this has occurred. In a Lead acid cell, the on charge terminal voltage is good indicator. Once this voltage rises past 2.4 volts the cell is charged. However, with NiCd and NiMh cells this not a very good indicator. With these it is better to measure the temperature of the cell and terminate charge when the temperature rate of rise exceeds a certain threshold. Li-ion cells require very close monitoring of both temperature and voltage to determine when full charge is reached.
Both the maximum Voltage and the maximum Current need to be controlled when charging. Too high a charging current will shorten the life of the cells. Too high a Voltage will lead to overcharging and shorter life. Lifetime of lead/acid cells is specified at the C/20 rate. i.e. the total capacity (C) divided by 20. Lifetime will not be guaranteed at higher rates of charge or discharge.
The charger that you decide to use should be selected as suitable for the size and chemistry of the Cells you wish to charge.
