BlackBerry CS-2 Original Li-Ion Battery for BlackBerry 7100, 8700, 8703, Curve 8530, 8520, 8330, 8320, 8310, 8300, Gemini 8520

After my blackberry battery decided to swell up and malfunction I needed a replacement ASAP - I came across this one and, although sceptical after reading the reviews, went ahead as it was pretty cheap. I have to say it worked perfectly and I had no problems with it at all.

My original Blackberry battery started to last around 6 hours, meaning I was rushing home to charge my phone or ending up with a dead battery whilst I was out, so I decided it was time for a replacement.This new battery not only lasts around 2 days per charge, but has also fixed my "white screen of death" issue.It fits perfectly into my Curve 8520, those saying it doesn't obviously have a different model and are getting confused.I would definetely recommend for anybody whose battery is on its way out, or who would like a spare for emergencies.

This battery lasted longer than my original battery that came with my 8520, but after a few weeks of use, the battery started to last for a shorter and shorter amount of time, and couldn't even last me past lunch time on a full charge.And I didn't even use the phone much at all, it was mainly just receiving a couple of messages, no using the Internet or phone calls!

Does as it should do. My phone was off for almost a month after my battery died (won't turn on) but then found this product. Put it on and ditched my nonworking battery and it worked, without me having to charge it first. So yes, it's good as new. If you're thinking twice about buying this, BUY IT. Very well worth the price and my phone's functioning good as it did before

When my phone battery was dieing I thought my life was coming to an end, that was until I came across this little guy. He may be small but he is full of power so much so it has given my little blackberry a new lease of life

Where should I start, firstly the product was defective, within a day of receiving the battery it just died continously and was much worse than my orginal one. It kept crashing my blackberry and after being fully charged it would show as till being uncharged. Then I got in touch with the sellers Alrana, they promised me an exchange so I sent off my battery it has now been a month I have no battery and no refund! I been emailing them for a refund for over two weeks and I have not heard anything back. Whatever you do please do not buy from them! Now I am back to using my orginal battery which actually works ten times better then the one they sent.

After finally ditching my 7-year old Nokia brick, I tentatively joined the smart phone generation, courtesy of my daughter's hand-me-down Blackberry.The original cell had been caned by 2 years of constant use and trickle-charging, resulting in it being able to hold a full charge for slightly less time than it takes to listen to the voice mail menu.This battery charges quickly, holds its charge well and is very cheap. The overall service was up to the usual (high) Amazon standards.To give it less than 5 stars would be harsh in the extreme.

I brought this battery as i had lots the original one. The first battery didn't arrive so i contacted the seller who kindly arrange another to be posted. I cannot fault the service and battery works as the original one :) Would defo recommend the battery and seller.

es un timo dicen que vienen dos beterias y luego solo viene 1 bateria no se merece ni 1 estrella

I was so happy that although my Blackberry is very old I can still get batteries for it through Amazon. The price was excellent and it was easy to choose the right one. The photograph of the battery was so clear. Thanks for having these batteries. Delivery was speedy and everything inside was bubble wrapped so it arrived without any damage.
