We only have the one robot because we have to carry previous parts over to new robots. Could it be possible that all 7 of our battery chargers are bad? We have batteries dating back to 2006, but we have the one from every year. We haven't load-tested it. How would I do that?

The battery drops just from the time we take it off charge, put it in the robot, and turn it on. It will drop to an unfunctionable 6ish by the end of a match. The compressor takes a lot, but our battery dies just by plugging the robot in and not even turning the robot on. At comps we plug in the battery then walk to the field and by the time we get connection it has already dropped from 12-9 and we can watch it drop by not even moving(without the compressor running)(and we'll be disabled). But our volt meter will read something along the lines of 13 before it goes in the robot. And then once the voltage drops it does not come back up. We only had this problem during off-season competitions and practice this year, but never before that.

Thanks for your help!
