Stuck battery bolt

[Grahamm]

Pair of mole grips done up very tightly is probably your best bet mate.

Unfortunately there isn't really space to get the mole grips onto the bolt

Cut the cable near the crimp and replace the crimp

Ah! Thanks for reminding me I've got a set of crimpers  :\

I bought them years back when I replaced the rear light with an LED one and since then they've been residing in a box.

I'll have another crack at it in a while and see what results...
