The battery started bulging within couple of months of use. In the first two months each charge did not last longer. The discharge rate was high even with no data plan.

I purchased this battery for my BB8520. The battery had a sticker with the BB symbol but it was not the usual BB battery hologram. I started using this battery. To my utter disappointment the battery discharged in 30 mins and the phone shut down. Please do not buy this product as this is not a genuine battery.

Great value for money. Have used this for a month. No issues thus far. Charges fast and holds the charge well. Packed well and delivered on time.

Useless battery.... It takes about five hours for full charging. It shut down the phone anytime without indication sometimes it within 15 to 20 and you can't do with it. Replacement service charge take 450 to 500 rupees, its not worth. Suggestion is not to buy..........

Very disappointing purchase from flipcart. Earlier wrong battery was supplied. The replacement battery arrived, which I could not use for some time. When I inserted the battery in hand set, charging showed "cross" over battery. Today when I went to repair shop, it was informed that Battery is defective. Mechanic demonstrated that set is working proper with alternate battery available with him.
What to do now. We rely on quality in name of Flipcart, but incidence has shaken my confidence.

wha...

I got the delivery within 1 week of booking on CAD basis.
Flipkar promised the delivery on 13th of June ,however they delivered the product 1 week before.

So on Delivery front: I am happy.

I am now waiting to see the performance of the product.

Secondly: I did not get this battery in box packing,rather it was bubble wrapped and it gave me the feeling that Is it a refurbished product or something?

I am taking a chance and wif this battery is not performing well.

I will sue Flipkart for sure.

i received the battery yesterday its not charging still now i put it into charge for more than 20 hrs

Battery stopped working within 15 days. Now I have no idea where and how to avail warranty of it.

I was not satisfied with the charging of the batteries ...I replaced after 30 days.... check with other vendors

Provides good battery backup, Battery performance looks Satisfactory for my 9700. Looks Original. Overall its a good purchase.
