This is my circuit for charging non-rechargeable 9V alkaline batt. and rechargeable NiMh. This circuit can charge 2 batteries at a same time. Don't throw away the money. 9V alkaline batt. has 500-600maH depending on manufacturer and can deliver lot of amps(comparing to zinc-carbon and NiMH). Chances for leakage are close to none with this circuit but checking on them from time to time would be prudent.
