Temperature Controlled NICD Charger

This circuit is for a temperature controlled constant current battery charger. It works with NICD, NIMH, and other rechargeable cells. The circuit works on the principle that most rechargeable batteries show an increase in temperature when the cells becomes fully charged. Overcharging is one of the main causes of short cell life, hot cells pop their internal seals and vent out electrolyte. As cells dry out, they lose capacity. This circuit can quickly charge a rechargeable battery pack without any negative effects. This circuit uses a 22VDC power supply, my version 2 circuit can run from a 12VDC supply such as a solar-powered or automobile power system.
