Battery

I'm running an Optima Yellow top. I've had a while and its still going strong nock on wood

Is that the factory battery still Josh?  I might need a new battery soon also.

We are running two red-top Optimas and put them in the Jeep not long after we bought it in 2011.  However, we will buy the yellow top once these die.

Im in a LJ with the group 34 battery but I did the Sears DieHard Platinum (rebranded Odyssey) when they were available.  I got the M group (marine) to get the extra threaded posts for accessories.  Had a yellow top before that and a red top before that.  All were good AGM batteries, but next go round I will probably just do dual costco generic marine deep cycles.  For the cost, I like the idea of having a backup battery even if its older style lead acid for the same price as 1 name brand AGM.

Optima yellow top for me. Free lifetime replacements.

Greg I currently have a five year old Sears die hard.

Thanks for all the feedback guys. I appreciate it. Looks like a yellow top is most popular. I'll have to read up on it.

I am running a Red Top.

On the TJ/LJ the dual battery set you have to lie them on there side. So unless your using sealed batters they will leak, even so a traditional wet battery wont hold up very long placed on its side.  The lead panels tend to brake off and short out.

That they do.  Would be a custom setup for sure.  LJs have a little more room under the hood as the evap canister is in the rear quarter and not under the hood.  Going to wait until i have tube fenders incase i go with ones that run custom inners but current measurements look good for a custom setup.  Also room in the floor behind the drivers seat as a backup location in the LJ.

Thanks Jeff. Very helpful.

I haven't heard anything about a blue top optima battery. This samurai I have been working came with a blue top battery and I'm going to run that in my jeep tj. It's an rv or marine battery so it's good for power and sure starts after sitting awhile. Any opinions on that one?

I had a blue top.  It didn't last very long for me.  The value was for a refrigerator in my case, where it was an extra battery.

I'm running an Odyssey. So far so good. They didn't have the Sears Platinum for the 2012 and up. Poles are reversed.

Why do you like this "Poles are reversed"?

2012 and up JK uses a different battery, Group 91 maybe? It is basically the same as the Group 34 of TJs and 07-11 JKs but with the poles reversed.  My guess is that this was the work of the same engineer that suggested the use of Torx hardware.
