[Battery Chargers for AA's]

The best source for battery chargers are HAM shops. HRO (ham radio outlet) is on the web. I purchased a MAHA charger and AA Nimh. Their full charge voltage is less than a Alkaline so don't panic when your battery level isn't max after a full charge. The AA's pack > 1500 mAh.
