My Digicool AK900s have started eating batteries. I've had them about 4 months. The battery that came in them lasted about 3 1/2 months, I changed it out with a regular Duracell 9v and it lasted about a week and I probably used it a total of 2 hours on. I changed it Monday and used it once yesterday for about 30 minutes and went to use them this morning and the battery is dead AGAIN! I tested battery and it reads 5volts so its definitely eating the batteries in the off cycle for some reason. I'm gonna try some expensive 9v now but if anyone (Doug) has any ideas of whats going on I'd be happy to hear it. Happy Independence Day, if we can still call it that, everyone.
