Location: north central wisconsin | I read all the techy jargon I could get my hands on 15 years ago or so, related to storage/longevity in batteries when I was having alot issues. The issues were related to how I was treating my batteries. My first revelation was 12-13 years ago, when I realized my developed no memory, purchased my first on-board charger, and began plugging in every time I got home. That portion of the longevity problem solved.
It was about then that I lalso earned it best to keep my batteries in cold storage instead of bringing them in over winter(central WI). Cold storage has added years to the life of my batteries, because I simply walk out to the garage and plug them in twice per winter now. Unless the battery is quite old, it never takes more than a couple minutes to read full charge, so the discharge is negligable compared to keeping them in the heat on trickle and constant wear. I also switched to Dekka Marine Master batteries about 12 years ago and my TM batteries now last over 4 years per set, and up to 6 or more on the starting side. Battery life comes down to care and charging, but also the amount of use/abuse given(charge cycles etc) and the Dekkas take an unbeleivable amount of abuse for the money. I was quite unhappy with the set/s of Walmart yellow Maxx's i ran for a few years(lost batteries while out of town and had to buy in a pinch), losing cells prematurely on 3 of 4. Probably just bad luck, but back on the Dekkas and satisfaction.
