According the the faq section on the Musicman.com website the average battery life is 6 months. I hate to throw away good batteries so I test mine with a multi-tester. The minimum voltage required to properly run the instrument is 8.4 volts so as long as the battery output is above that it should be okay
That's good info right there! Thanks Kevin. I guess I should stop using my tongue as a tester.![]()
