Re: (ET) battery gases
Double check that the individual battery is reverse charged. Isolate the
battery. Discharge it with a resisti e load, like a car headlamp. Put it
on a 6v charger to see if it will recover. Sent from Samsung Galaxy
smartphone.

battery gases Sirs,I am on an "old man" streak . Turns out I installed
one of the batteries (lead acid) backwards and charged the pack for about
6 hours and of course had no real power. Studied the installation and
found the problem (me)! I disconnected it but now I am uncertain of my
next step. With red tester lead on + post and black on - post shows
"6.2v", reversing the leads shows "-6.2v" so I'm thinking the polarity did
not reverse. Should I charge it separately for awhile or just reinstall
it among the pack and start charging (and thank my lucky stars)?Again,
thanks for your collective expertise.Mike On Wednesday, April 19, 2023

try industrial battery suppliers. David Roden - Akron, Ohio, USA= = = = =
