Photography is my hobby. Now I'm 23, I'm Taking photos from the age of 10. Why I'm saying this is I've bought a lot of rechargeable batteries during this period.

Common issues faced in Rechargeable batteries
1. Capacity --> you should buy above 2000mah - which is available in common nowadays.
2. Another issue is the free drain time.
You may be aware of this. so let me explain it. Recently I have bought some Sony and Hybrio batteries. (sony 2500mah, hybrio 1800mah)

Test 1: (continuously taki...

Very good product. Last wk i received the product. One set of two barrery i have loaded to my digi cam and still taking photographs with it, and count is 300+. In other i need to recharge daily but with sony nh-aa-b4kn over one wk without recharging. great....Thank you flipkart. Even the review i read about the product and fond it helpful for my decision for purchase.

Purchased this for use in toys for my daughter. Very good performance. Mostly used in a remote controlled car and once charged can be used for many days. Since batteries are pre-charged, it can be used right out of the box.

Flipkart did a good job of packaging and delivery.

I had ordered this Sony NH-AA-B4KN battery the battery over all performance is better when
compared to other fast draining cheep batteries. But if u guys want the battery in ur hand early this is not the right battery ur looking at because of my experience i'm sure it will take more than a week to get delivered...
this is the only set back for this battery other than that the battery is working fine...
if u r looking batteries for ur camera this one is better than other fast drain type bat...

These are the best rechargable batteries that I have used for almost all of my electronic gadgets which include cordless mouse, cordless keyboard and also my camera. They have given me the best battery life per charge when compared to other brands available in the market.

I already owned a set of Sony rechargeable batteries and another similar set of batteries from a different company. Sony batteries outlasted the other brand's batteries.
I needed another set of batteries for my camera and so I went for this one.

Unlike my old set of batteries, these batteries do stay charged even when unused for long periods of time ... didn't really test for the 1 year claim .. but I have used them over intervals of 2-3 months with satisfactory performance.

So far did not ...

I have ordered this product a week before and i was not disappointed as i received it in couple of days, quality packing as usual.
Before buying this i was using camelion battery 2100 mA. Performance of this is superior to my previous batteries.
this is my fourth or fifth purchase from flipkart and i am fully satisfied with its price and quality service.

Fine battery backup. Decent price

good

Good one. Using over 5 months. Found no problem so far.
