Where to buy new battery for TT one V2

[wakefield]

My old battery is almost dead but I am confused as to which battery to buy. The installed battery says its an Edinburgh battery F64390435 but all the batteries for sale say on ebay for TT One V2 have another part number F650010252.
Can someone help me to find the right battery and where is the cheapest place to get one in the UK?
Thanks

Google has about 1,660 results for 'F650010252', but not a single one (apart from this topic!) for 'F64390435', so I'd go for the one listed.

Are you confident of installing it yourself? Otherwise http://www.satnav-shop.com/ would be a good bet to supply and install it.
