I doubt it but I'm not sure, I put the red top and the winch on at the same time-new.
But I got 3 red tops now in the shop one new 2 little older.
Cant get them to keep 12v or more.
Charge it to 12.5v and in a few days it is at 11.88 or so.
Still will start the rig but can never get it up past 12.8 then it drops off.
Before you say anything, it has nothing to do with the rig. NOT A THING. not the charger, I now have 5 to make sure it was not the charger.
I have had them look at the battery and the others and everyone was stumped. then we tested a few new ones to find that they only go to 12.2 to 12.3 new, but the Lead acid cheep ones and high ones are at 12.8 to 13V
Why???
after a week its at 11.2 will start the truck slow but does it.
Before you say the truck it draining it, Dont... I have removed them for testing reasons after use... I say its bad battery but at 12v it will test fine around 800 amps or so.
Tried playing with the winch to see if the battery would run it in and out, it would but slower then using a lead acid that was at 12.5 plus, more amps... it would just sound like it was draging a little. also it was not under load but you could see and hear the difference.
Try your slow winch on a lead acid to see if there is a difference.
