The useful charge on a backup battery varies a lot based on usage. we're not using a camera or servos this year and we could run all weekend on a single charge, last year's lasted about two or three matches, (a servo and a camera).
We've had good luck using the pre-2007 chargers. If you don't have one available, stop by Team 85's pit in Archimedes. I'm pretty sure we still have two in the tool box (on it's way south already). It's quite easy to monitor the backup battery voltage on the operator interface. We like to see a voltage of 7.8 volts before starting a match.
