Last night I found one of my lawn mower batteries (group 31, 12V) at 8.8V after a fresh charge. So, I know I reversed a cell or two in it. I'm looking to fix it as its not that old. A quick google says to discharge the battery FULLY and then recharge at a low amperage.

I'm wondering if anyone knows anything about fixing those reversed cells? Have you ever tried it?
