Our Mustang came with a trunk-mounted battery and a rather nicely made mount from Jegs. But beneath the battery, we didn’t like what we saw: a crude little patch.
What was the patching covering? We investigated and, sure enough, found some poorly repaired rust.
While the affected area was small, a rear spring mounted nearby so we considered this part of the car to be structural. We tore out the mount, ground down the patch, and welded in a larger, thicker one.
Optima does a lot in our motorsports world, and we’ve had good luck with them in our BMW M3 and Porsche 911 project cars, so we ordered another one.
The company’s D34 offers 870 cranking amps and should be perfect for our high-compression Ford engine. As our car now uses a trunk-mounted battery, we needed to factor in some loss due to the longer cables.
These batteries are widely available, with Optima offering them direct for $299.99.
