Done some tests and now I'm sure my batts slowly going bad so need advice for a new one. Gets down to around 0 deg F around here so I'll need one with good CCA.

Any suggestions?

 

Some will say Diehard Platinum and some will say Interstate. Otima isn't as good as it used to be.

 

If you are a Costco member their batteries get very high ratings.

 

If your serious about off-roading look into an Optima. Otherwise duralast is ok, but i'd reccomend getting an OEM battery, none of the junk from places like AutoZone or AdvancedAutoParts

 

I'm pretty happy with my Optima red top, been in for about 4 years.

 

Deka is all I use.

 

Fleet farm has store brand batteries. 55$ and the last one I had lasted 5 and a half years. Never had a problem with Walmart or autozone batteries. But they were more expensive. It's all preference. My parents and I are on the cheaper side for batteries.

 

I'm using an Optima Yellowtop that's at least 6 yrs. old.

But whether they are worth the cost, I don't know.

I think there are plenty of batteries that will last longer than that with proper maintenance.

 

+1, I use NAPA batteries, which are made by East Penn/Deka.

 

Of the conventional flooded lead acid acid variety, get the smallest one close to OE with the best warranty (probably the most expensive). Don't buy into the 90000 CCA bull**** - you don't need it:

Jeep OE batteries in Group 38/74 were about 500-600 CCA off the lot. Jamming them full of lead to the point that they generate 1000+ CCA is not good for longevity, in fact many owners that bought those batteries report shortened life. Because the plates are too so tightly packed they short out from shocks and vibrations much more easily.

If you really need that much power look into an AGM like Optima or DieHard, go dual-battery, or look into a larger battery that can handle that kind of density reliably (truck size). Although if it takes a lot of power to start your Jeep when it's cold maybe you should look at cables and the starter lol.

I run the smallest most expensive store-brand. Basically an Exide 670 CCA Group 34/78DT. I expect a good 10 years out of it.

 

Thanks for all the advice yall.

Little tip on getting into Costco I just learned about. If you have a costo gift card they'll let you in the door (never have been stopped anyway) and let you make a purchase (or cartload) no matter what the value of the gift card. So if your giftcard has .01 on it you can pay with your card first and then pay the rest with cash.

Nother note...you can get low dollar gift cards to costco on ebay for like $3 to your door. It might make more sense for you to get a membership but if not then maybe this'll be an option for ya.

 

Battery discussions are like ATF, motor oil, and spark plug discussions.

I've always used Group 34, 700 CCA, batteries in the Heep. Any of the POS batteries out there are only good for three years - four on the outside, so why waste the bux of big top (or whatever you call them) batteries.

 

Shell or NGK batteries? GO!

Well, mine came with 1 year roadside assistance... my keys don't work in my doors . Oh, and a decent pro-rated warranty period. I paid about $110 for my 670 CCA, parts guy counter kept saying "ITS ONLY FIFTEEN FOR 980CCA", I told him to keep it.

 

Optima it's what we use in humvees and other equipment like tugs and what not so I got optima. I have a yellow top in a truck for 4 years no problems, a red in my 70 Chevy for 2 years no problems and another red in my xj no problems

 

Good advice. Last battery cost me around 8
$85 for a group 34 interstate. Had about 700 cca iirc. What you'd benefit the most from would be a cable upgrade from 5-90. Less voltage drop= more cranking power.
