Fixing a reversed cell in a lead acid 12V battery

[Daox]

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?

hmm, I've never heard of "reversed cells" except as a temporary thing, and then how DO you discharge it completely?

A ----|-2v+|----|+2v-|---- B
A conductor from A to B won't conduct.

Are you able to volt probe from plate to plate, gently, through the water ports?

I'm not sure, I might be able to. We shall see.

I saw a clip on youtube that demonstrates a lead acid battery being mostly restored by adding Epsom salt to each cell. I'm not sure how this works, or why everyone doesn't do this when their battery falls low on voltage or CCA.

is it a flooded battery? if so, make sure all the cells are full up to the top of the plates at least and put it on a charger, I would start out with a 2amp charger and let it sit for a few days to see what it does, I think draining it down to dead is how it got this way, so that will just make it worse!
