I was in the exact same dilemma a few month ago for autox. I went to autozone and bought the universal battery hold down. It's actually a heavy duty product. for about $3.

You remove the battery tray, set the battery on it with the lip under the factory tray "wedge" that's on the front edge, line up the autozone holdown piece, drill a hole where needed and reinstall tray with bolt through the bottom. Put the wedge shape piece over the lip on the bottom of the battery. Tighten the nut, and that battery isn't moving.

I could lift real hard on the battery strap and nothing budged. The battery tray will break before anything else.

All for $3.

I've got a ratchet strap holding my battery.....safety steward saw it, laughed, and said nice...

That's probably the strongest and most reliable hold down you can have. When's the last time you saw a stationary ratchet strap break?

A concern w/respect to a ratchet strap would be that acid vapors can weaken the strap material. Under high G loads the the strap could fail and the battery could come loose. There will not necessarily be any obvious signs of damage to the strap beforehand. I'll leave it as an exercise for the reader to figure out why I'd be concerned about this.

I have the factory tie down on both my cars... never had a problem driving hard or Auto-xing.

so run a sealed battery!

his work was awful though. good idea, bad outcome. that battery only needs to slip 1/2" and zap...lots of sparks.

Most straps are made of nylon, I.E. - plastic. So I don't think battery acid would hurt it any.

Yeah, we busted on him a little about it. All it really needs is some side support/another beam the other direction to stabilize it and it would be rock solid.

Here's my optima mounted in my car. Battery cover is a tight fit, but it works.

I can move the whole damn car with my battery. :)

Mine is similar to your Sean - I ran a piece of steel stock with holes in it under the battery tray and used the j-hook kit.

At tech, they yank it hard, and the whole car raises up.
