7 year old "mopar" case battery by "jim"

[leroy]

i purchased a mopar case battery from "jim's battery about 7 years ago... and i was wondering if it is a flooded cell or agm battery... can't remember if i checked for water in it but had white plastic strips covering the plates...so i filled it with distilled water over the plastic strips and drove it a hundred miles last year, it will crank over and start when warm... just wondered if it still good, because it costs $300, and i have heard some bad things about these batteries, and i don't know which way to charge it, age or flooded...any help ?

I would put it on a low trickle charge (2amp) until it comes up to snuff. Then drain it with something like headlights. Repeat this several times. This has worked for me before. Nothing to lose by trying.
Good luck

I've had great luck with NoCo chargers...

Those batteries are maintainance free and the accompanying paperwork repeatedly says DO NOT add water or acid.

Pretty simple. Pull a cap and if you see lead plates it's an acid battery. Pull caps and see smooth plastic there is a sealed AGM inside the case. I bought my script battery in 2017 and they were already AGM's.

Antique Auto the predecessor to Jim's was using AGM in 2010 when I bought my Ford script battery.
