Right, i suspect this number isn't going to be so useful as it appears i just asked for a place to buy a spare battery, not a high capacity. They're open workdays so i can't phone and check today: 0870 8531005 but i will phone Monday if i get a moment.
As a quick aside, there's these guys who you could enquire with:
http://www.cybex.cz/Produkt.aspx?Sho...K&CategoryId=0
These guys list it also:
http://www.apexis.cz/iobchod/cze/pro...t=0UP#pro49034 and have a slightly more professional looking website.
and these guys have a photo:

oop, and these guys for 58 euros:

I'll be contacting all these people at some point, but i thought i'd put them here so if others are in more of a hurry they could have a go too. That second-to-last shop is in the Netherlands, and if we fail to find a battery anywhere else and they won't deliver outside of their country, i can get a couple from them. But i'll be trying all these places first, and more if i find them.
If anyone contacts any of these places, please do let us know what they say.
