Wasabi Power Battery (2-Pack) and Dual USB Charger for Sony NP-FZ100, BC-QZ1 and Sony FX3, a1, a9, a9 II, a7C, a7R III, a7R IV, a7S III, a7 III, a7 IV, a6600 (KIT-BB-FZ100-02)

Hands down best value to power your new generation A7 and A9 series cameras. I've tested these against Sony brand and these offer the exact same runtime. Charging takes slightly longer, also depends if your charging two at time. That said, the value and most importantly the footprint is why you should buy these. For instance, the charger that comes with he A7riii is horrible. Its large, and comes with a cable, really? a cable Sony? Stop it with that garbage. The charger for these are small and LIGHT. This matters for todays shooters, every inch and ounce counts when we get out to gather imagery. Wasabi saw this and made in my opinion a near perfect solution. One caveat. The area that the usb cable connects to to charger is junk. They are junk on this model and they are junk on the previous models. The area of contact needs some some basic engineering to create a more stable, reliable and DURABLE connection point for the cable. This is the point of failure on these things. Take caution to ensure proper functionality. Also plan to have back ups of chargers, they are so small that having additional should not be an issue. Now click purchase and be thankful that you now get two batteries and a charger for the price of one Sony battery.

I've been using Wasabi Power products for years (since the Hero 2 came out!) and have learned I can count on them for quality. These batteries that are compatible with the Sony A7IV are no exception. While they don't last exactly as long as the manufacturer brand does, they come pretty close at around 92% of the original's runtime. At this price point I feel like that is a very good bargain. The dual charger included is very helpful after a long day of shooting when i've drained all my batteries and need them back in action the next day. I highly recommend adding these to your kit instead of spending twice as much for half as many batteries.

If you dont want to spend a lot of money on the genuine battaries, this would be your absolute best option. They are high quality and almost as good as the original ones!

Edit: Changing my review to 4 stars because the company on their own accord issued a full refund and an apology. Customer service is great. I bought this set of batteries on Jan 31, 2024 and after very minimal use they keep triggering a safety warning on my Sony FX3. This warning shuts down the camera. Unfortunately, these batteries don't do anything for me since they can't be used with my camera at this point. I would not recommend them.

Para los usuarios de la Sony a7III en particular vi muchos modelos en internet en donde la cámara la detecta como modelo de "3er party" a modo de advertencia, con este modelo no sucede y funcionan excelentemente! lo recomiendo mucho

I bought those Wasabi batteries and charger from Blue Nook last year after purchasing the Sony A7III. They were working great, every bit as good as the Sony battery. However after two firmware updates (2.0 and 3.0), the camera started displaying communication errors with those Wasabi batteries. The error message generally pops up 5 minutes after a Wasabi battery is inserted and the camera is powered on. The message can be dismissed to allow the camera to function but then cycle repeats itself when the camera is turned of and back on again or a Wasabi battery is inserted. I also had an issue with the included Wasabi charger. During the trip, the status LEDs charger stayed red for both batteries but neither was charged. I contacted Blue Nook and reported those issues. They promptly sent me replacement Wasabi batteries and charger. The replacement batteries restored the compatibility with the A7III camera. The replacement charger also functioned normally.

I am impressed by the quick response info@bluenook.com when I reported my case to them. Battery display not indicated in my camera monitor and they replaced it right away with a new one and now is working pretty good. Shout out to Terry

Love Wasabi batteries. Much cheaper than OEM, and the battery life is just as good. Would definitely recommend to anyone!
