I have 5 Deka marine batteries that are 6 years old. Used and abused on boats.
Probably go with the same when I replace them. Or some other East Penn made battery.
I was told by the Jeep body shop and by Jeep (877-426-5337) that the repair must be completed before the warranty expires.
I questioned if documenting the corrosion was enough for coverage and was told no.
I will pursue this further.
