We have not had any voltage problems with the new batteries, but have lost 6 batteries due to swelling this season. We believe that the swelling problem is due to our bank charger which we have now discontinued use with, prior to the swelling we had noticed that it was charging hot.

We did have a voltage problem in 2006. The battery in question read 13.5+ volts off the charger where it had been for an hour. But once the match started it failed to even move the robot and read something like 7 volts.
