Duracell Premium Analog Sony Np-FW50 Battery for ALPHA A7 A7R A7S 7.4V 1030mAh

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!!!!

Good product. They retain their charge well.

I bought this about a year ago in 2025 as an extra battery for my Sony RX10 IV Bridge camera along with a Duracell charger and Anker 12W USB A charger. So far the Duracell has held up very well and works without any issues in my camera. I've only ever charged using the official Duracell charger with a high quality Anker USB A charger and it charges perfectly every time. In terms of how it compares to the OEM Sony battery that came with my RX10 IV, it's very close, I would say it lasts at least 3/4 as long. When you consider that an official Sony battery costs around £55 and this Duracell, around £20 then even if it doesn't quite compete in battery life then this is more than acceptable, I mean you could buy nearly 3 Duracell batteries for the price of 1 Sony! If Durability/Reliability is a concern for you, then I would really recommend charging with the correct charger, Duracell sells single and double NP-FW50 chargers. I use a single slot charger along with an Anker 12W (2.4 Amp) USB A charger and that has worked brilliantly for the last year or so, if you use poor quality chargers, you may be damaging your battery's. All in all, if you want the best alternative to OEM Sony, buy one of these.

This is a cheaper alternative to the official Sony camera batteries, the current price (£14.99) is under a third of the price for the official Sony batteries, meaning you could buy 3 of these and still have some change left over. I own three of these, two of them still work, and one of them has died completely. The official batteries have longer battery life, and seem far more durable. Not sure I would buy again, as I can't seem to find the process for returning the battery, despite the 2 year warranty. Edit: I contacted Duracell direct, and they exchanged the faulty one under warranty.

I use these for my Sony Camera. Great battery, good value for money.

The notoriously power hungry a7R II lasts little over 40 minutes when recording Super35 4K with SLog2, which is a hair better than the original sony ones. I bought the duracell batteries as I don't trust the optimistic higher capacity ratings of the cheap and cheerful alternatives available (usually £5-10 each), and got exactly what I paid for. Still a shame that I need to carry four of these for a day of moderate amounts of pictures and video, but luckily Sony fixed this in their latest gen cameras.

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.

Excellent replacement vs. the original Sony, with very good longevity vs. my other cheaper alternative batteries. Purchased two of these and they by far outperform all my other ones. Highly recommend.

La compre como batería complementaria para mi Alpha 6000 de Sony y funciona perfectamente. Tiene un pelín menos de carga que la original, pero funciona correctamente y dura mucho. Ya había comprado de Duracell para una Nikon que tenía y funcionaba la mar de bien. Recomendado al 100%

prima vervanger voor de dure originele sony

Pas de surprise, bien adaptée à l’appareil et pas trop cher

Had one before, good quality!

Ottima consegna e ottimo prodotto
