I’m surprised the info it people didn’t respond to this. I would also like to know because I run a repair shop and was interested in a case, of 6s batteries, but not if they’re going to completely die from not being charged
I only ask because I left marine battery in storage for over a year and it was dead when I pulled it out. The guys at West Marine said thatvthere was no way of reviving it, and that I should have had it on a trickle charger
