My brand new calb 3.2 v,180 ah batteries purchased from bls show some swelling straight out of the box (1/8"on the sides.). Each cell is uniform in slight swelling and has 3.26 v charge. No capacity test yet.
I assume this is a bad sign and am prepared to return the batteries regardless of what a capacity test would show. The question is: is slight swelling acceptable in a new battery, or any swelling at all unacceptable?
