new battery, have used wood packing - is this ok?
So my old battery lasted 4 yrs, and died when I left the headlights on for about 10 mins last week (while setting up a tent in darkness!).
It was surprisingly difficult to source a replacement here in Australia, as most of the big name stores simply don't carry the exact model that fits a 159 3.2.
So I managed to find a Varta (german made) of the correct spec which is correct width and length, but the height is 175mm instead of the correct 190mm.
This leaves a 15mm gap under the strap when I put the battery in. I read that it is ok to simply make up the difference with some wood, so I sawed up some old hardwood flooring I had lying around (exactly 15mm height), and laid it in the bottom of the battery tray, then put the new battery on top of that.
Is this a fire hazard? On super hot days here I'd imagine it gets pretty toasty under the bonnet, so I just want to make sure I've not done anything stupid here.
