Sony NP-BX1/M8 Lithium-Ion X Type Battery (Silver)

Works fine in my camera

One thing I've learned over the years is that you get what you pay for. Although most brand specific items are a bit pricier on one hand, I've rarely had issues when it came down to where the rubber meets the road. Photography is a passion and I used to use "other brands" to save money. Well... it's a 50/50 shot as to what the ultimate satisfaction will be.This battery is an extra, to have ready when I need it. As with other Sony batteries, I've only had one, in the past 8 years that's had an issue. It turned out to be a crooked contact within the top cap. Amazon sold it direct and I had a replacement within a day and half, sending the other back through an easy and simple process, dropping it off with UPS. Done deal.Yes... it's a little more than most, but I still have many of the spares after all these years and have never had an issue with charging, sudden or dramatically shortened use cycles, or someone passing off a fake that looks like the genuine Sony product. I've stated many times in other reviews that buying an items that's directly from Amazon or Amazon playing the intermediate, has proven the way the go. Mind you, there've been rare occasions I've purchased from "other" sellers and the inevitable happened a couple times. Read everything and save a copy of the actual description page for that seller. Trust me... it usually will turn out in your favor, as it should.But, back to this item, you can't go wrong and it's been used in my Cybershot camera's with no signs of degradation after using and charging at least 3 complete kill/charge cycles a week sometimes. They get used in the DSC-HX50V and the DSC-RX100 v1, which I bought recently and will review. All I can really say is that it's the perfect battery for both of those cameras. Paying a little more in the beginning has given peace of mind that they'll work when I need them to and they'll last a good while before needing replacement. It all comes down to the usage patterns.

Don't jeopardize your camera with an inferior battery

Sometime in 2024, Sony switched their packaging. It's no longer comes in the clamshell. It's in a cardboard box now. Just putting this out there in case anyone is worried about checking the authenticity of their purchase.

Bought these for my Sony ZV-1 vlogging camera. They are excellent and last like the one that came with the battery. Bought a multi-battery charger that came with an aftermarket battery and these last around 20% longer than the aftermarket battery. Would buy again!

Bit pricy

Sony battery for my Sony. Easy to use and charge.

I bought 3 of these batteries, and they all worked just fine in my Sony RX100M4. I just got back from a trip, where I took between 300 and 500 pictures each day, and I very rarely had to use the third battery - it was really just a spare. I'd say that for any normal person, 2 batteries should easily get you through a day. It's hard to say how much battery life I got, because in addition to just taking a picture, I do a lot of zooming in and out, checking the display, etc., but compared to other cameras and batteries I've used, this one was very satisfactory. I was also happy with the charge time - I could charge two batteries overnight (I had to change the battery in the charger when I got up in the middle of the night, but for me that was fine.)A couple of other factors to consider: My camera does not have a viewfinder, so I'm always using the LCD screen. Also, because my camera is extremely good in low light, I rarely use the flash. Both of these things are relevant to battery life.
