We take all the batteries to a local auto parts store for load-testing at the beginning of each season. They will test them for free.

The batteries need to last for a single match w/o impairing performance. Normal engineering practice is to design for a 2X margin so our robot generally will run 2 matches on a single charge but we NEVER do that (always replace the battery for a new match).
