Battery size? Also, what happens if I disconnect the battery?

Loads of people put battery in the boot, my dad use to do that **** when he was young. Anything that gets rid of a little weight from the front of the fabia is a good thing IMO!

That's the thinking!

I don't know how much a battery weighs (I assume it's heavy), moving it to the boot, and replacing the spare wheel with a can of tyre foam, is a cheap way of increasing the handling. Even if it is only slightly.
