What devices does the Batt-O-Meter work with?
The Batt-O-Meter works with almost any active instrument pickup or effects unit (stompboxes and other floor effects) that require a 9 volt battery to operate, and is turned on when a standard 1/4″ cable is plugged into it. The Batt-O-Meter can test stand-alone batteries: 9V, 1.5V (AAA, AA), and 3V. It does this, by automatically placing the battery under an appropriate load to simulate real world usage. It works with Alkaline, Rechargable (ie. Lithium-ion, NiCd, NiMH), and old school Carbon-Zinc batteries.
