Lots of experience with the yellow tops.
Bottom line is they do not have enought capacity for serious winching.
Sadly Johnsin Controls moved the factory from Denver to Mexico and a lot was lost in the change. The reliability wend down hill
The days when I got the employee price of $65 are now gone.
What to choose.
Sure, this thread mentions a lot of acceptable batteries. I have 4 of the Optimas still in use in my 3 rigs. Replacement will be the highest reserve amps(20 a rate) for the money. Right now the size 65 from Walmart is a good choice. Lots lead means lots of amps for the winch.
If you cannot find the spec for reserve amps use price per pound and a good guide. And never buy a flooded battery AGM is the best. As was mentyioned forget about the 6 pac and just get the sealed cube style.
Not sure the 65 can be squeezed into the Jeep, but it fits fine in both Broncos.
