I have a need for a simple inexpensive charger to charge 3 NiMh cells at = 300ma. the cells have a capacity of 1800ma. Has anyone developed such a = thing either using a PIC or not. Ideally it should have a timeout as = well as a secondary backup for overcharge The circuit must not continue to trickle charge after battery is full, = or if it does at a very low level as I am told that NiMh batteries = cannot tolerate a continuos trickle charge, correct or not?
