Hello and welcome to my Sony a7III battery and charger guide which aims to cover all you need to know about which batteries and chargers can be used with the Sony a7III, including both original Sony and third-party options.
For those of you that own the Sony a7III you most likely already know that it doesn’t come with a dedicated charger like its more expensive siblings the a7R III and a9. But don’t threat, because as well as Sony’s official charger there are also a number of third-party chargers that you can use to charge the Sony NP-FZ100 battery that the a7 III supports.
Sony a7III Official Batteries
If you want the best possible battery life from your a7III and guaranteed compatibility then I would highly recommend sticking with the official Sony NP-FZ100 battery. However, please be aware that Sony has issued a warning regarding counterfeit NP-FZ100 batteries which bear the Sony logo and look very similar to the genuine Sony battery pack. To avoid purchasing counterfeit NP-FZ100 batteries, I’d recommend only purchasing from official Sony approved dealers. Also, if buying from Amazon make sure they are coming from Amazon directly and not a third-party seller.
Sony NP-FZ100 Battery
The Sony a7III uses the new NP-FZ100 which doubles the battery life compared with the smaller NP-FW50 battery found in the a7 II. Still, if you are shooting all day then you will probably go through at least one battery. Personally I’ve never gone through more than two NP-FZ100 batteries in one day whilst shooting wildlife and motorsport (stills) with my a7III. If you are shooting a lot of video then you may well go through more than two batteries.
Battery life stills: 2000 shots (best I’ve got when shooting sports/wildlife).
Battery life video: 2.5 to 3 hours (approx)
Recharge time (with Sony BC-QZ1 charger): 150 minutes (approx)
Recharge time (in camera via USB-C): 285 minutes (approx)
Sony a7III Third Party Batteries
Very Important Note: With recent firmware releases and new cameras Sony has really gone to war with third-party batteries. When used many third-party NP-FZ100 batteries will display a warning message stating that the operation and safety of this battery cannot be guaranteed. You can ignore the warning by pressing OK and the batteries will still work, however the percentage indicator next to the battery icon also disappears so you will not know how much battery you have left. My advice would be to stick to the official Sony NP-FZ100 batteries, saving a few dollars by purchasing third-party batteries that could potentially damage your $2000 camera is not worth the risk.
If you do insist on using third-party batteries in your a7III then the RAVPower NP-FZ100 are reported to work well and not throw up any error messages at this time (this could change with new firmware updates). These batteries are also bundled together with a dual charger.
Battery life stills: 1500 shots (approx)
Battery life video: 2 to 2.5 hours (approx)
Recharge time (with Wasabi charger and wall adapter): 180 minutes (approx)
Recharge time (in camera via USB-C): 300 minutes (approx)
Sony a7III Official Battery Chargers
Unlike the Sony a7R III and a9, the a7 III does not include the Sony BC-QZ1 charger in the box. I can only guess Sony needed to save a little money somewhere with all the technology they packed into the a7 III, and so the charger was dropped. You can still charge in camera via USB-C, but this takes approximately 285 minutes to fully charge one official NP-FZ100 battery, compared with only 150 minutes when charged via the Sony BC-QZ1 charger.
Sony BC-QZ1 Battery Charger
The Sony BC-QZ1 is Sony’s official battery charger for their NP-FZ100 battery, it will charge a single battery in approximately 150 minutes.
Sony NPA-MQZ1K Multi Battery Adaptor Kit
The Sony NPA-MQZ1K multi battery kit might be a very useful addition to your a7 III if you shoot very long video sessions and need as much power as possible. This kit can charge four batteries (NP-FZ100) in approximately 480 minutes. It also allows you to power two USB devices as well as the camera at the same time. The NPA-MQZ1K also includes two NP-FZ100 batteries, a cable protector and a mounting plate. You can find full details on Sony’s website here.
Third Party Sony a7III Battery Chargers
If you aren’t keen on paying for the official Sony charger or would like a dual charger, then there are a number of third party chargers on the market. My personal preference is again to stick with the official Sony chargers, especially when charging the official Sony NP-FZ100 battery.
Watson Mini Duo Charger
If you are after a low cost dual charger then the Watson mini duo charger is one of the better options. It’s a USB charger so isn’t the fastest, but will still charge two NP-FZ100 batteries in around 5 hours. So more of a charger to leave on overnight than for a quick charge during the day. The charger features built-in overcharge, short-circuit, and power surge protections.
