This. I accidentally put a battery just like this in our robot in 2009, went from 13 to 7 volts after the match started (the battery had been killed by trying to test a motor that was shorted, and happened to find a way into the rotation of good ones).

You can ask Akash, we were allied with 11 in that match. There's nothing worse than losing a match because of an error.

Edit: I wish I had a battery beak, it would have prevented the mistake from ever happening. Reason being that the battery beak puts a load on the battery, so if it's actually dead, the beak will show it. Best. Tool. Ever. Wish they existed in '09
