I ran into where you can ride your batteries hard and recharge them hard, and keep them at full capacity for maybe 5 yrs, OR treat them kindly and keep them for maybe 10 yrs at something less than full capacity.
I need the full capacity while camping way more than I need more than 5 yrs from the batts. If the positive plates fall off after 5 yrs I get new batts, and same for antimony poisoning, battery trench foot, and battery hoof and mouth. Too bad, so sad for the batts. I get to go camping my way.
I learned how to do that from Barre's book and then from guys on this forum over the years. JiminDenver is right. Each to his own taste.
