I was about to buy one of those UK gold batts..now glad I didnt.

I did however, buy a pair of oem looking batts (about $5 and free shipping) to try from the cellshop on ebay..one was dead on receipt and the other one sort of works but isn't as good as my original OEM.
For $5, I'm not complaining.

btw,
lshal command shows :
battery.reporting.design = 1294 for my original Nokia batt.
battery.reporting.design = 1250 for the cellshop ebay batt.

I would think somone could make a double thick batt around 2500mah and provide a new back with a slight bump out...that would sell..even if it was made up of 2 nokia OEM batts stacked.
This is a great forum...!
