    Subject: Squeezing a battery
    I recently built a battery holder for an Odyssey PC545 battery to mount it o n the firewall. 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? Thank you Sebastien

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

    I don't want to shim out with washers as I'm worried about stressing the firewall but I will make two full sized plates to shim out if I have to. A good point thank you.

    It looks like somewhere between 10 to 30 washers could give you a snug fit as desired. > On Jul 28, 2016, at 10:56 AM, Sebastien <cluros@gmail.com> wrote: > > Attachment was too big. > > <image1.JPG> > > Sebastien > >> On Jul 28, 2016, at 10:36, Sebastien <cluros@gmail.com> wrote: >> >> I recently built a battery holder for an Odyssey PC545 battery to mount it on the firewall.
