About Batt-O-Meter Guitar Pedal And Preamp Battery Tester
The Batt-O-Meter from Keith McMillen Instruments is the first battery tester for musicians. Test the remaining hours of battery life and voltage of 9 volt batteries while they are still inside gear through a 1/4-inch plug. The Batt-O-Meter works with almost any active instrument pickup or effects unit (stompboxes and other floor effects) that requires a 9 volt battery to operate, and is turned on when a standard 1/4-inch cable is plugged into it. The Batt-O-Meter works by automatically placing the battery under an appropriate load to simulate real world usage. A micro-processor within the unit allows the device to intelligently determine the different loads that can be put on the battery and calculate the power in hours remaining. This eliminates the need for extra buttons and adaptors, and makes the Batt-O-Meter simple to use. The Batt-O-Meter can test stand-alone batteries: 9V, 1.5V (AAA, AA), and 3V. It works with Alkaline, Rechargable, and old school Carbon-Zinc batteries. The Batt-O-Meter requires its own 9 volt for operation, which it can self-test. Located in Berkeley, California, Keith McMillen Instruments (KMI) is an intimate company that makes innovative technology for string instruments. A portion of each KMI sale is donated to the BEAM Foundation for research and provide commissions for new musical works.
