After being given a Blackberry phone as a hand me down I was quite pleased as I would be able to access all the features of a smart phone. Alas this was not to be, as I soon found out the battery was faulty or at least I thought it was the battery. Looking around on Amazon I found that a Genuine Blackberry battery replacement was a lot cheaper than I though, so I took the plunge and ordered one, it arrived in very quick time and was the correct replacement and it was the genuine part. My phone has since been working without problem and the battery life is excellent. If you have a problem with your Blackberry then try this first "Genuine BlackBerry C-S2 Battery For BlackBerry Curve 8300, 8700, 8700c, 8700f, 8700g, 8700v, 8700t, 8700x, 8700r, 8703e, 8707, 7130e, 7100i, 7100g, 7100r, 7100v, 7100x, 7105t, 7100t, 7130c", its a snip at the price backed with all the excellent service you get from Amazon.
