Optima Single Battery Box

Optima Single Battery Box

We made these with the fabricator in mind.

These are made of 1 piece of steel, no welds needed! We made them with very tight tolerances so the battery will not move around and the top plate is also cut in a shape to fit the battery. They have no predetermined location holes cut in them so you can use them as best suits your project without having to work around someone elses idea of how it should be done!
  • Fits Optima 34/78 battery
  • Battery box inside dimensions W:6 7/8" L:9 3/4" H:6 5/8"
  • Yes you read that correctly, these measurements are different from the dimensions listed on Optima's website. Optima includes the terminals and battery cap dimensions which sit above our boxes sides/ hold down.
We used mild steel because stainless just isn't necessary in something that is not a show truck and why add $50 to the cost if you don't have to? These are for an Optima 34/78 battery, the most popular size. The Optima battery can mount to either side and they are unidirectional so you can't mount them wrong!


Note: This battery box only fits the Group 34/78 Optima Red, Yellow, and Blue top batteries. It does not fit the Group 34, 34R or 78. It must be the Group 34/78.

By Dan Wierman in WA on 4.11.2017
When I did the V8 conversion in my Bronco II, I needed a larger battery. The existing tray is really too small. When I found this battery box, I knew it was what I was looking for. With the clean cutout and bends, this will be a great and good looking addition to my project build. Quick delivery too! Thanks!

This thing fits my Optima battery perfectly. Very well made. The steel is thick and strong enough to be absolutely solid, but still light enough to be reasonable. I fabricated my own mounts to mount this in my 99 Cherokee XJ and found that I was actually able to fit my battery lower and further inboard than the stock battery, which was a major bonus for my situation. I couldn't be happier with this product.

Mike on -- Asked: Looking at the picture, I assume that this holder will clear the blue top threaded studs as well? Thanks, Mike

Answered: I'm not sure what the stud distance is on the blue top, but the hold down necks down to about 1 5/8" wide between those points, and this width extends 1.5" from the edge of the battery before it starts to widen.
