Battery tie down?

#1

What is the standard for anchoring process for the battery? Everyone just build it from Home Depot?

#2

I did, long threaded rods and aluminium U-channel top and bottom (with stock tray)

The stock anchor works fine for me.

After doing some fine welding work and spending too much time at Home Depot, I’ve found that the factory box is the best answer.

I was using the factory mount. When I had my big crash at Laguna Seca, the mount broke and somehow the battery moved in just the right way to push the insulation off the positive terminal and made contact with the nicely grounded chassis sheetmetal nearby. Luckily, none of the electronics were damaged. I’m going to come up with something beefier for the rebuild.

Is that legal? I thought we were to use stock style batteries?

When I replaced my battery, I ordered what the Interstate guy had for a 1989 BMW 325i…

Carter, I don’t recall that battery tie down modifications are addressed in the rules. May want to specify a modification for better retention. I’m using the stock tray and it’s not confidence inspiring.

I removed the factory tray, used two lengthe of steel 13" long, one across the top of the battery and one on the bottom of the battery box (on exterior of car), two legths of 5/16" All Thread rod and some hardware. Drilled holes in the bottom and viola, 20 minute job and it works great.

Batteries may be replaced
You can actually make a braket it like that for the oem battery as well.

8.5. "Replaced" means that the item may be replaced with items meeting or exceeding OEM specifications.

don’t think the small size battery meets OEM specs (for CCA’s for example)

I see, size.
No, I meant the dry cell battery, which is a lot safer (exceeding oem specs), and the bracket just to give an idea of what else can be done.

Here is another idea you can make

#18

this shows one of the problems with the definition of "replaced" - which OEM specs are important, and what is "better".
