SonyNPFW50 Battery

I have been using Sony cameras NEX and A7n and A7rn that take this battery for many years now. Put off by the price of the OEM units I researched and bought recommended 3rd party batteries. I tested these for capacity and only one brand had equivalent, or better capacity to the Sonys, this was DSTE. Satisfied, I bought several DSTE batteries.In early use the DSTEs were as good as my Sonys, but after a few months I noticed that they began to sef-discharge rapidly and gradually lost capacity.I still have the Sony batteries that came with my cameras, they still have good capacity and hold charge well on the shelf. ALL of the 3rd party batteries I have tried are long gone, they simply do not last, and these were brands recommended by users on the net.I only buy OEM Sony batteries now, and not one of these has let me down so far (touches wood). In this case the old adage "if you buy cheap, you buy twice" really does apply.

Not much more to say, these are great and last long. Considering how expensive cameras can be I wouldn't want to risk putting a 3party battery in it!

After some of the negative reviews I was very apprehensive about ordering this battery, and it was only the security of Amazon's outstanding Returns policy which convinced me to at least give it a try. The size and weight match my original battery and there is only a very minor difference in the labelling. After giving it an 80% charge my Sony CX5100 Camera has worked perfectly with the battery losing 1% per day on standby, so those negative reviews are a tad confusing. The full RRP is ridiculous which makes this Amazon price far more acceptable, although it's still too high for what it is.

ITS SONY IT WILL BE GOOD

Great battery, it is a feuine Sony battery and as expected performs very well. It does seem to be expensive for a battery but the price on amazon is cheaper that others I have seen. Really happy with it regardless, definitely worth buying original batteries instead of other brands

I bought this battery believing it to be a genuine Sony product but it is not. An examination of the batteries label will review this. It seems to work fine on my a55 but fails to operate the NEX7. Disappointed in not spotting this earlier.

Really great to have a backup for my wedding cameras. Super great and useful

This is so much better than another aftermarket brand that I purchased from Amazon. That didn't last half as long (in fact about a quarter) as this Sony one. Not really saving here.
