Group 31 battery install (1 Viewer)

[MMaxim]

Hello everyone.
I have been a long time follower, and I think it is time to contribute something to the community.
I always wanted to install Group 31 battery, but was having trouble finding a good description of the required modifications to the tray. Someone recommended cutting ribs out of the tray but it made it very week. So I decided just to make a battery tray myself to provide a very strong platform and at the same time great connection points for battery tie down.

Battery fits well, and I am not worried that it will go anywhere! I will share more details if anyone is interested. BTW positive basbar is covered with a plastic cap and was not installed when the picture was taken.

Nicely done! What's the thickness of the bar you bent for the mount? Did you use a brake or just do it in a vise?

 

[MMaxim]

The bar is 3/16. Made a template out of copper wire, repeated with the bar. Have a press brake that I made to go with my 12 ton press.

Group 31 that I have is too tall to be sitting on top of OEM tray. I had to cut all of the bottom out. Some sheet metal also had to be punched in for more clearance.

Wow! yeah, that looks sturdy enough! Nice job.

Very nice. I’ve been threatening to make one for years but every group 31 I’ve ever bought just dropped in with an extended tie down bar I made. This looks more secure. Might get inspired soon.

Mine was a bit too tall. Additionally, I always wanted to have a metal platform there.

Haha, not sure!

It might be a design worth selling to a vendor for production while ya still can.... I'd buy one.

Just my .02

No reason other than my local battery store had one in stock that was the closest to 1000 CCA.
You are right, there is a ton of info online. Just keep researching and it will all become clear quick.

Would you ever consider making one of these for the passenger side? I am trying to install this but she's a bloated cow.

Let me look into that.
