I'm looking into getting a new battery since once a month my jeep decides it doesn't want to start. I like optimas but they are a little pricey. Any thought? Btw I'm new to the forum.

:D Overland Journal, which is a pretty well known off-road/expedition magazine, did a test of the top six vehicle batterys, in the Fall of 2010 and




Heh Heh, thanks kbw--I use it mainly for my fishing boat, but it's a dropin for the jeeps battery--shouldit fail--

Now The OJ, thru very exhaustive tests votes for the Sears "Diehard" P4, as the BEST all around and DEKA was second, while Optima ranked third-

Now I still have my original ('08JKUR) battery/ with no signs of fatigue, but-

My next battery(if I don't use the bluetop Optima) will be a sears "Diehard" P4--it also comes with a 4 yr replacement warranty (did)--

This journal tests everything we use, tents/recovery gear/winchs/tires/wheels/coolers/gas/water cans--including the jeep JKU for overlanding--I've hada subscription for over 6 years and will keep it in the future, it's quite a mag. with unbelieveable photos, of off-road vehicles in some impassable spots--then they show how to improvise and MAKEIT (McGyver)---:rofl:

:D Yeah, but It should cover most of the West coast and Sierras and-




If I hit "dead" zones on the mountain top, I can use my Delorme files for terrain and GPS

My main attraction to AT&T, is years of association and there Nevada coverage-

I've read good reports on the Sierra wireless aircard-

Which are you using and have you had any trouble ??

I'm a fan of OJ but some of their test methodology is sometimes, errrr, flawed. They only have one real science guy (and he's brilliant).

But anyhoo, Optimas are great batteries but not the only battery. Different methods of building them make them better suited for different tasks.
I happen to think the Yellowtop is about the best for a Jeep battery. From what I've read, some branches of the US military agree with me.

If you join Powerpack Nation you can order the batteries directly from the factory to your door and get them at a discount.
I got my pair from the factory so that they'd be matched by build date.

More knowledge for the notebook. And on multiple levels. All I can say is...:D

I must admit that my notebook is mostly in my head. Nevertheless, the pen register leaves a lasting impression...

Thanks for the kibble.

I've ran Optima Yellow Tops in previous vehicles and always liked them. As you said, cost is an issue.

I find my cheapie Everlast battery from Walmart or Autozone does just fine in the Jeep. As I recall, the last one I bought was only like $60.

Auto/man?

From another forum --

"if it's an auto, try putting in neutral or taking out of park and firmly putting back into park. some the 07s and 08s sometimes don't make the switch that indicates park position. if it's a manual, then battery, starter, connections, switch. may even be the way you hold your mouth. it's a JK, problem solving is anybodies guess."

:D Yeah DM, the OJ mentioned that a couple years ago, I wonder if it's still the case-?




A good practice for lead-acid battery longivity, is to always maintain the DISTILLED water level and use a battery maintener when the jeep isn't being used--course if you driveit every day--moot point !

I went with an optima yellow top as I couldn't leave the autoparts shop for the price! Other top names for batteries: Oddessy or Diehard Platinum and Northstar.

:D What the hey, willee, I wouldn't sue you for copyright infringement, if you made some CDs/Sandisk's--


.. if the Wolfman, Jimbo and HD (the Lightman) keep posting great info, I am going to have to upgrade my laptop memory to a few Tetrabite :thumb::rofl:
Nobody in their right minds would believe us anyway !!

Don't tellem you heardit from me !:rofl:

:whistling: I knewit-

That reminds me, I just gotta "HEART" royal flush in one of my little town Casinos--$800 bucks and this is the first Royal in Heart, I've ever gotten (28 royals)--

A mere $800 bucks--I should probably donateit to a worthy cause !

TOO LATE--I gaveit to me !:rofl:

alternator, belt, parasitic draw. Those are a few.

Parasitic draw is analogous to leaving your dome light on. If it stays on, it will kill the battery. A vanity mirror light that stays on because of a broken visor hinge (happened to me) will cause a parasitic draw.
As will an aftermarket radio, a TIPM that won't go to sleep, etc.

You can google and test this with a multimeter or a snap-on MT500, etc. A tiny draw is normal, but 0.1 amps or greater signals a draw. In the old days you could pull fuses until you found the circuit, a bit harder on a TIPM equipped vehicle.

The alternator can be (reasonably) tested by Autozone.
