Will This battery work in a 7100i ? This is what the battery says:
Blackberry C-S1 7100 g/r/t/v/x Li-ION Extended Battery 3.7v - 1500mAh



All comments are greatly appreciated

Yes, I saw this battery on ebay. I am assuming you saw this also. I was wondering that myself but it looks like it is a battery not meant to be used in the US but that does not mean it will not work. You should contact the seller.

Sorry this is a month late in reply, but 1500mAh cannot fit into a battery that size. Take a look at some of the technical specs of Li-ion Polymer batteries (e.g. at this site: GlobTek Li-ion Polymer Battery ), and you will see that you can estimate the max capacity by taking the dimensions in cubic mm, with 0.1mAh/mm^3. For the 7100, the dimensions are about 55x34x6 which is 11220mm^3, so the max we could get would be 1122mAh. Since part of that size is taken up by the plastic housing, the original battery's 1000mAh is already the maximum capacity you could get. In order to get 1500mAh, the battery would have to be 50% thicker, which wouldn't fit in the case.

Batteries which are sold on Ebay with "huge" capacitie are fakes (the MaxCell 1700mAh, for example, is a known fake).
