Matt,
When I was in high school (a long long time ago in a galaxy far away...) I worked for an auto parts store that had an actual tester for these devices that charged them up to full charge. We sold Delco parts and this part was from the Delco Remy line. After testing we would throw them to each other as a joke. Just one of the things that contributed to the callouses on my hands.
