dual battery in a TJ/LJ???????

[gijohn40]

so has anyone put dual batteries in a tj/lj? where did you mount them? I have seen the one that mounts two optima batteries but it is only for them... so where would those that have other types put a second battery? There is a great place under the tub in front the rear axle that a nice box could be mounted but it would have to be a weather tight one.

I am just starting my search so haven't really looked yet.... forgive me.

I think I've seen them vertically stacked on the passenger side of the TJs? Let me see if I can find a picture?

I could be wrong but I think know DAA has dual battery's in his LA

the dual optima set up does have them stacked but like I said you have to use the optima nothing else fits

This is the optima set up... and as you can see regular batteries would not fit in it...

Yes one of the problems with wanting 2 batteries is that optimas are smaller than most lending them to the task.

I had a friend that put an optima blue top under his bronco, he never had any issues with it. I believe he had a skid plate and covered the terminals in grease. I don't know why you would need a sealed box for any sealed battery, so long as you stay out of river crossings. (even sealed batteries have vents on them) (Do not take my one story as a good thing to do but it has been done so it is something to look into.)

btw I stuffed two red tops under the hood of an xj, they are small batteries for sure...

Anyone ever thought of running two 6v optimas or the like? As I understand it 6v are much better for deeper discharge recovery and overall better performance. So you could run two 6v next to each other in the same space as a 12v, but have a better system than just one 12v.

I don't. Thought I wanted a dual batt setup, for years. But after years of looking at the expense in the neighborhood of a kilobuck for the systems I was interested in, and realizing I'd been getting along just fine without, I decided I really don't want one after all.

I do carry a jumper pack, the Antigravity gear one that doesn't weigh anything or take up any space. But I haven't needed it either.
