Hi Mate,
Yes the Nono (Nano) battery should fit, according to a thread in another section (Support and how to)it has been done, which is why I decided to search out some betteries and do it too!! Just have been comparing Ebay scammers..... err I mean sellers
ops:
I was kinda thinkin too that there must be better than 330 mAh but the only ones to suit the clone are the Nono betteries anything else is way to big to fit into the SMALL space that houses the factory bettery. One Ebayer has a 400 mAH for sale BUT for some reason I had a spazm in my gut saying.... RIP OFF. If you check out the pix of the betteries you will notice thay have a fold over thin card that has some spec written on it, it seems a little sus in one 400 mah add. I may be very very wrong, also another guy which I emailed about this fact, and low and behold the whole add changed on the ebay web page :P ,, stating the right mAh rating
Ebay (A place for big ripoff merchants )
Just a few words of warning
hope it helps
Joffa
