NP-FZ100 Battery 2 Pack and Dual LCD Charger 2500mAh,Compatible with Sony A7SIII,A7iv,FX3,FX30,A6600,A7,A1,A9,A9R,A9S,A9II,A7RM3 A7RM4,A7C,A7III,A7RIII,A7RIV Li-ion Battery

All good batteries and fully compatible with my a7iv no issues or warnings on firmware 3.02, the charger also has a built-in USB lead which is a nice touch as I often forget mine.Update, It is no longer compatible and gets a warning on a7iv after updating to firmware version 4.00, still good batteries but you will get the warning when using them.

These batteries do exactly what they say on the tin. They are a larger capacity than the original Sony batteries, (which are 2200 mAh I believe) these are 2500 mAh and they do last longer too! They are the most value for money batteries for my A7iii and I can only highly recommend them to anyone!

The Powerextra NP-FZ100 Replacement Battery and Dual LCD Charger set offers both convenience and value, but it comes with a few caveats.Firstly, the inclusion of two batteries is fantastic, providing extended shooting time for my Sony camera without worrying about running out of power. The 2500mAh capacity is decent and gets the job done for most shooting sessions. The dual LCD charger is also a handy addition, allowing me to charge both batteries simultaneously, which is a time-saver, especially when on the go.However, there are some drawbacks worth mentioning. While the batteries hold a decent charge, I noticed that their lifespan seems to diminish slightly quicker than the original Sony batteries. Additionally, the build quality of both the batteries and the charger feels a bit flimsier compared to the original equipment. I've experienced occasional issues with the charger not recognizing the batteries properly, which can be frustrating when trying to charge them efficiently.Overall, the Powerextra NP-FZ100 Replacement Battery and Dual LCD Charger set offer a good balance of power and convenience at a reasonable price. It's a worthwhile option for photographers looking for extra battery capacity without breaking the bank, but be prepared to deal with some minor reliability issues along the way.

These batteries are doing their job fantastically. This is my second round with this brand, and I'm still giving them a thumbs-up. Okay, they might not have the stamina of the original batteries, and yeah, you'll get that famous "not using the original battery" warning, but guess what? I paid less for two of these bad boys and a charger than I would for one of the original ones. Bargain!Now, I've got a couple of genuine Sony batteries, and they're the real MVPs, no doubt. But when I needed some extra juice, I go for these budget ones.Quick side note: After all these years, only one of the batteries from my first order is still working, and it's doing it well. But, hey, I'm forgetful when it comes to charging, so I had to grab some more. Oh, and these new ones seem to lose a few percentage points of charge every week, unlike the OGs. But hey, they're still keeping my cameraalive!

Happy

***Manufacturer replaced my faulty items and I’m pleased to say that currently both batteries and charger are working as expected.***The battery charger has two docking bays one of which fails to charge batteries on my unit. The integrated usb cable is handy. The biggest problem is with my a7riv one battery is useless as it is seen by the camera as incompatible. The other battery does deplete slightly faster than the original Sony battery but all things considered if it functioned correctly this wouldn’t be a big deal for me.

Nice item

Great for the price and comes with charger with usb attachment attached meaning they can be charged in the car and with % so you can see how much is on it. I’ve used a few times and no issues so far.
