If its an ordinary lead-acid type,you can get them from Hein Gericke for 30 quid.
Dunno about the "sealed for life" type tho.

Thanx again for the replies , managed to source a battery now had another problem with the bike after that but managed to sort it out by removing the eprom chip and replacing it again and has seemed to sort it out.
Unfortunately havent been able to ride it since then as i've buggered my knee up (gutted).Hope the weather holds out for a bit longer.
