. . . is lore we all learned from our dads. It used to be true, but not anymore.. . . put it on a piece of wood . . .
I dunno, I find that leaving the battery on fiberglass is best. (In other words, IN THE CAR.)
I kept our Esprit's battery on a cheap Harbor Freight maintainer during the two years I was rebuilding the engine and transmission, no issues after that.Regarding float chargers, you could leave a 250 - 500 mA dumb trickle charger (or better yet, a trickle charger with a brain box) on an unused battery for 6 months straight with no ill effects.
I agree - Optima batteries are not worth it. I will be on my third Optima Red Top for my 98 Esprit. I am currently trying to get the current Red Top replaced under warranty - which does not hold a charge. Optima's warranty service is atrocious, in my opinion. You have to use the SAME dealer that it was bought and/or deal with their laundry list of requirements/testing/questions to get them to do anything. I am communicating with them via email because the person I spoke with on the phone, in their customer service, was a jerk. If I had to do it again, I'd avoid Optima batteries.Interstate MT-56. Stay away from the gel cell type batteries like the Optima. Expensive and not worth the extra cost. With good care a battery should last at least 5 years. Always keep it fully charged. To do that use the car regularly if and you don't, then use a Battery Tender at least for 1 day every 2 weeks. Use the hold-down hardware and if it is missing get it replaced so the battery doesn't bounce around. If you see the headlight pods "pop up" when you are starting the motor you let the battery get too low. If you put the car away for the winter remove the battery to keep it warm, put it on a piece of wood, and charge it for 1 day once a month.
