Thought I had left a bit of wiggle room to get the battery i n and out but now that it's bolted to the firewall it's in there tight. I do n't mind having to remove 5 bolts every couple years to remove the battery ( better than remaking the holder) but will it damage the battery to squeeze i t? I don't think there is much if any pressure on the battery but it's alrea dy going to be stressed sitting in the heat in the engine compartment. Do th ese batteries need room to thermally expand at all?

I don't mind having to remove 5 bolts every couple years to remove the battery (better than remaking the holder) but will it damage the battery to squeeze it? I don't think there is much if any pressure on the battery but it's already going to be stressed sitting in the heat in the engine compartment.

If so, you can shim the battery box out from the firewall with a washer or two under each mounting bolt.

A good point thank you.
