Can you "recondition" lead-acid batteries?

With non-sealed lead acid batteries get drained in the cold weather, i usually pull them and bring them inside my house an let them warm up for a good day before I try and recharge them.

I have had as good or better results with them as I do with Kinetik

I use them in every install now

in fact I have a customer with a 99 Quadcab f150 that had 3- 250 amp mechman alts take a crap on him in less than 1 yr trying to push 1 deka 31 and a brutus 2400d amp so we went back to the original stock alt ( 135 amp ) and 3 of the BT120 batts and he maintains 12.7+ volts at all times.. and has not had a single electrical problem since...

( and my prices are as cheap or cheaper than that egay link you posted and IIRC so is Sonics ...)
