Imported goods like car batteries are difficult to get hold of here. After half a day trying to find somewhere that sold a battery of the right size and specifications that hadn't already gone flat on the shelf, I got it home and, before fitting it, noticed that it was the opposite way around to what I expected - positive on the front left, negative on the front right.
I didn't even know they made batteries like this, so I never thought to check.
I fitted it turned around, so that the positive connected to positive and negative to negative.
It seems to work fine, it's just rotated 180 degrees and I had to adjust the terminals to get them to fit.
Is there any problem with having it fitted like this, or precaution I should take? Possibly overthinking things, I put some electrical tape on the back of the positive terminal, since it's closer to the metal chassis than it normally would be, to reduce the chances of something conductive bridging the gap between it and the negative chassis.
