2012 drove fine two days ago, came out yesterday morning and the battery is so dead it could nearly unlock the doors. I was getting on to the forum for help to find the electrical short, until I saw this at the top. Of course I never trust advanced to check my batteries, they never got it right when I had opimas. how can I test the battery, take it to sears?

Kind of true, but not really. Good batteries under no load will read at least over 12.6 volts. If it's reading 12.0 you got real problems, unless you left something on that is draining it.

I installed this little $5 voltmeter in my rig after experiencing the dead battery. Probably one of my favorite cheapo mods to date. The 11v is ignition on, no running engine and the 13v is engine running, ac on, lights and done light on. Not that it helps when the batt is dead but peace of mind when running lights, winch, etc. I also bought the Li-Poly battery pack that can jump your vehicle. There are three brands available. Can't recall which mine is but a good option for $125 vs. installing a second batt. Particularly when I want the genesis kit, which done right, by their recs, will run about $1g.

it will hit 14's when driving, lights out, etc. I'm not particularly concerned for absolute accuracy, as long as I have an approximate. Which most people deal with on analog vs. digital. And, for $5, I didn't expect perfection.

Took mine out the day I bought it. Mine is an April '12. Put the battery in my sons car and it lasted about a year. He has a Hyundai Elantra and a small alternator. The stock battery is not exactly a great battery. It is barely sufficient for getting the Jeep off the dealers lot. Add some accessories and it's gonna be a short lived part.

Just lost my factory battery this evening. Cranked fine to pull out of the garage so I can put the top up. Could not get it to crank to pull back in......
I've noticed a few weak starts but never anything worrying. I would have had this one for 2 years in just over a month. I guess my plan to get a better deep cycle has advanced in schedule
