Evening. Hoping for some advice, having searched and come up blank.
i have 2 X 190AH Lead Acid Batteries 12 NDT-190 Narada. After lockdown, around 3 weeks back, we found a wrotten egg smell in the office.
We found the one battery had leaked a little acid. I removed them from the trolley and took them home to check on a smart charger.
They both reached 100% indication within 5 minutes.
What would possibly have caused this and is it safe to put them back into service?
They were lying on their side in the trolley for as long as they have been in service.
Appreciate the help.
