PowerextraReplacement Sony NP-FZ100 Battery and Dual USB Charger for Sony ZV-E1, FX3, FX30, A7C, Alpha A7 III, A7R III, A9, Alpha 9, A7R3, a6600, a7R IV, Alpha a9 II, Alpha 9R, A9R, Alpha 9S Camera

I have only one battery for my Sony A7 R 4, but was going on a trip where I was going to be experiencing extreme temperatures and I didn't want to have to worry about my battery dying. I researched many brands and this had the best ratings along with a great price. Best of all it came with TWO batteries and a dedicated charge.

Works great and holds the charge on my A7RIV. It’s as good, if not better, than the OEM that came with the camera. For the price, you get two awesome batteries and a dual charger. This is by far the best deal on any charging system I’ve ever seen. Mirrorless go fast through batteries, so don’t go pro with one or you will be s.o.l. This is a great investment, much better than OEM stuff because of the prices.

Items arrived fast. Exactly as described. I charged the batteries and was surprised at how quickly they reached full charge.Fit well to my Sony ZVE 10 11 camera

It gives me same juice as a sony battery, really recommended

The charger works great. Charges one battery well and my original Sony battery. However the second battery it came with is dead. Cannot charge or anything after just one use.

Muy buenas baterías, funcionan en la cámara sin problema

**Edit**In my original order, I had 1 battery that drained noticeably faster than the other (probably about 75-80% of the run time of the other battery). Even after a few charging cycles it was the same. Their customer service reached out to me because they read this review, and offered to replace it with no charge. I received the replacement battery and it works perfectly. I've used this brand for my Fuji camera too without any sort of issue - and it's great knowing they stand behind their product! Buy without worry!!!**Original**This is the first time I’ve ever had any issues with Powerextra (I also have batteries for Fujifilm) - but one of the two batteries drains noticeably faster. I thought maybe it was because I was pushing the settings and runtime on the A7Siii but after a charge, 1 does rundown quicker than the other. However, the other battery does perform just as well as the Sony OEM so I’m still coming out ahead. The one that drains quick, I’d say is about 75-80% capacity of a Sony OEM.Between my cameras, I’ve got 10 powerextra batteries, so you can still buy with confidence. I’ve heard 3rd party batteries can be more finicky, so maybe I got one that the camera doesn’t recognize like an OEM?? It’s also the one that triggers the non-sony battery warning on occasion.I can’t comment on longevity yet, but if it’s like the ones I’ve got for my other camera then there shouldn’t be any issues. However, I rated the product a 3 because of the performance inconsistency - but if I order more with no issues, then I’ll revise my score.

I bought this charger and battery combination because I upgraded to a Sony a7IV. The batteries took a few hours to charge but held up through 3 photo sessions before needing to be recharged.
