ok i may be being completely stupid..
but look at this auction on ebay: here
look at the S/N (serial number im guessing, rather than me being dumb) its 0712281 yeh? well i've got a battery here with the same s/n ie ive got the battery in the picture (i think..)... and yes i won the auction but i won it last night, and so i'll be getting *that* battery in a week or so..
hmmm seems a bit odd to me
edit:
ok, slightly less of a coincidence perhaps, looks like the guy i bought my t610 off also bought something from the guy im just buying a battery off.. still wierd i feel
