Charging Batteries is not a simple process. Many chargers use crude methods shcu as a single resistor and/or diode to generate a set current. This and other crude circuits are very bad for the battery life and should not be used.

The ONLY way to get the maximum life out of a battery (or single cell) is to use a Charger Circuit specific to the battery type and chemistry. I have designed EVERY charger type possible and would be happy to assist you.
