Before ordering, I read several reviews which had diagonally opposite opinions whether the received batteries were fake or genuine. It wasn't available with WS-Retail whom I trust most. Finally gave a try with Gadget-guru and got a 100% genuine battery in original pack and properly sealed.

The battery's charge/discharge/usage pattern resembles to that of the original which was received with my Blackberry 8520 phone, as observed for more than a week.

Delivery was fairly quick. Packing perfec...

My original curve 8520 battery had bulged due to overcharging and was not holding charge for more than 4-5 hours.

I received this battery from flipkart few days back. On the first day after complete charging the battery went on for over 16 hours till it showed the low battery signal. During these 16 hours I had used the phone for about 3 hours of talktime and constant usage of phone for blackberry enterprise data plan for official mails and other apps like whtsapp, bbm, gtalk, facebook etc.

Not very effective in solving Blackberry's battery issues. My older one used to work for 3 hours, this one works for 5. The only difference :-)

and Yes it does sometime runs out even when there are like 2 Pillars standing

The Product is good, I have got this 15 days back and working fine with my Blackberry 9300, the charging cycles are fine and its giving me full day long charge to work with emails and internet browsing.

Thanks to flipkart the product was delivered well before the prescribed time. The packaging was good and secure. No signs of tear or any thing.

Well coming to the product it didn't look like the battery that came with the phone in the first hand and no signs of bill or any warranty. It lasted for a long time same as the original battery and didn't overheat also.

I have purchased this battery from flipkart to replace my existing Blackberry battery which was three years old. Now it is almost a month and working completely fine. It is always a pleasure to have a deal with Flipkart - quick service and timely delivery, good packaging and value for money. I am able to purchase this battery from flipkart with the difference of Rs 200 as compared to existing market price. I would like to highly recommend to any customer looking for the same product.
