This is part of the reason I like the interstate batteries, they come at a decent price at Costco and they don't test them on a return, they just give you another.
A few years back I did quite a bit of research into batteries since my golf cart takes 6 8v batteries.
I didn't know duralast was on the list, I tend to avoid anything with the name duralast on it.
During my battery research I read about quite a few tests of desulfators too. It would appear if you have months to wait for a battery, they actually work.
I think the one I bought for my golf cart batteries is a battery minder, I got it cheap since they discontinued the 8v version.
I'd say it definitely works, BUT it literally takes months, with 6 batteries it could take like 2 years to do them all, lol and buying either 6 8v minders or one 48v minder would cost half as much as new batteries.
For the golf cart I don't think it's worth the effort or money.
But for a car where you probably put a tender on it in the winter, i'd say it could work.
Btw, the battery in my car currently is a diehard I put in there 7 years ago.
