The charge rate on it is pretty low. If the battery is discharged put the big charger on it first, then the minder.
I have finally found a battery it couldn't charge, the battery in Angie's 2005 Golf TDI has croaked. We got the car in (checks blog) 2015. It's got a VW branded battery in it so I know I didn't put it there. The car has sat a lot this year due to some stupidity on my part, then it got used around town some without being charged first. I put the minder on it a week ago but I think it's got a sulfur bridge, it won't take any charge now... -Curt On Friday, September 1, 2023 at 05:35:56 PM EDT, Floyd Thursby <buggeredbenzm...@gmail.com> wrote: I bought a couple of those battery minders, one is hooked up to what seemed to be a dead/dying MB battery, it is still charging after 3-4 days with no error light so maybe it will rejuvenate it a bit. I'm gonna fetch the battery out of that tractor next week and will put it on the other charger and see what it does. She did go by El Mercado de Wal to see about getting another one but of course they were all sold out. I told her not to get another one if this one can be charged up OK which would probably indicate one of these other parts --FT On 9/1/23 5:31 PM, Curt Raymond wrote: > The battery Minder that I got from Northern Tools has been magic at saving >lawnmower batteries.
