Someone "paid" me for some time with a brand new motorcycle battery.
(He bought a 12 volt when he needed a 6 volt, and I wasn't going to
charge him for the time anyway) I have a wave runner with a 4? year old
battery that still works great, I hate to replace it when it works so
well. (It spent most of it's life on a good battery maintainence charger)

The question! He filled it with acid then I slow charged it. Can I
preserve the new battery by emptying the acid then letting it dry?
