Duracell Premium Analog Sony NP-FW50 Battery for Alpha A7 A7R A7S 7.4V 1030mAh

Nice item. Great deal.

I dont normally buy none genuine batteries, but being from duracell, I thought i’d give it a go. Easy to use and functions as expected providing the same battery life as the Sony equivalent. Used multiple times and seems to be durable so far

After sifting through the many battery's advertised as 'genuine replacements' for the SONY NP-FW50 I decided to try the Duracell type as the name is trusted, and the price is about 60% LESS than the genuine SONY battery. The Duracell works OK in my new ILCE-5100L SONY camera, and works normally in my new SONY Genuine BC-TRW Charger.( Purchased because I don't like charging battery inside my new camera in case of melt down!!) You do need a spare battery with this camera as battery life is not very long!! I wish Amazon would clarify when products are GENUINE SONY----as many listed play on words and pictures don't show SONY logo!! Never buy the cheapest product advertised!!!!

An affordable replacement battery from a well know brand.This battery works well in the camera (I have a Sony A7R II) and I have not noticed a significant different in performance to the original Sony battery.One point to note is that this battery does not fit into the (Sony BC-VW1) charger very well, it seems a little small. This means that the battery does not always charge. However, if you charge your battery in the camera, this will not be an issue to you.

This is the third such battery that I have bought - not because there is a problem, but because now I have two cameras using this type of battery and I wanted the extra confidence of having three spare batteries between the two cameras. They seem to last just as long as the original Sony batteries, and I have not noticed any drop off in the time between charging for the older batteries which I bought a couple of years ago.

As an alternative to Sonys NP-FW50 this Duracell compatible battery is stellar! With the Duracell version being 60% cheaper, I was a little hesitant but brand power counts. The battery charged up quickly and when using it for a similar length of time as the Sony one I have it it dropped out maybe 5mins before the Sony after using it for filming. For the difference of £30, this is perfectly acceptable.

This product was inserted straight away into a Sony camera and it worked fine and has been working fine since. It was great value for money. So all's well. It's a well-known brand with a good reputation.

It works. But on my a6400 the battery indicator is hella unreliable. It goes from 50% to 5% in minutes. Yet somehow lasts an hour on 0% sometimes. Official sony batteries don't have this issue. I hate to say it but i feel it's worth spending that extra for the reliability of official sony batteries. I won't be buying another battery.
