Flat Battery

I think that's the problem. Easy to pierce the 6 cells one by one and empty into a bottle.

But is anybody going to buy a new battery for that?  Might take the acid out of a knackered battery.
And a bottle of caustic soda is just a couple of quid.
Do our gel pack batteries really need to be banned?

I was wondering about that. I bet they don't buy brand new motorcycle battery kits very often to get hold of the acid. It's one of those situations where the legislation catches-all I imagine.
