You would need to separate the two batteries and test them independently. It's a very flawed system. If one battery begins to fail it will suck the life out of the other one until they're both dead.Is there a way to anticipate this? Iām at 2.5 years on the oem batteries and I really donāt want this to happen to me in the boonies. Should be under warranty? If I get past the warranty period on the original batteries I will probably look at an auto start stop delete and a genesis dual battery system for reliability purposes.
FWIW, I replaced both of mine and almost made it three years as well. I used a yellow top to handle winching better, and a die hard aux 14 for the aux. it was a straight forward replacement. Sorry yours wonāt start.I almost made it 3 years but my OEM batteries have died.Everything was fine yesterday but this morning was click-no-start. I knew it was coming so I should have ordered batteries to be ready but I didnāt.

Also, I canāt recommend the fender removal to install the replacement aux enough. It makes it so easy. Just get some replacement white fender clips in advance.FWIW, I replaced both of mine and almost made it three years as well.

I keep mine on an AGM battery tender. It's habit now whenever I park it in the garage. It's hardwired with a connector near the winch.I have to start preparing for this , I have 22, and when I don't drive it for more that 3 days sometimes it has issues cranking
As of your post, you have/had 2,654 messages on this forum and 26,542 miles on your JT. You may want to play the lottery tonight. And that is low miles for three years.I almost made it 3 years but my OEM batteries have died.Everything was fine yesterday but this morning was click-no-start.

Which one did you get?I have the batteries but the manager at Oreilly says the aux may not fit. Sheās had complaints in the past. I will find out soon
That should fit fine. Mine was a die hard, but also aux 14.
That's the correct one. You'll need a 4mm socket to transfer the posts between the batteries.
From what I recall the Mojave and Rubicon's had the larger batteries.Interesting. The search told me group 48 but itās smaller. I must have a group 94

Pretty easy to keep track - just check voltage at rest now and then.
None-driving is a battery killer for most modern vehicles. People in a NAPA store were complaining they can't get batteries in their cars to last 4 years or more.
If you want to make them last longer, BatteryMinder will handle it (I put a tag on my door handle when it's plugged in to remind me but with this setup, it would simply pull the connections apart and do no damage) ->

@ShadowsPapa Bill can you elaborate on that plug setup? I think I'd like to do that setup.
Did you hookup pin #1 and 4 ?
