Nitecore has announced the NFZ100, the world’s first ‘smart battery’ for Sony full-frame mirrorless cameras, including the a7 III, a7R III and a9 systems.

Like most ‘smart’ electronics, the unique feature of the NFZ100 is the ability to manage and monitor the battery with an accompanying smartphone app. Nitecore NNERGY, as it’s called, is available to download for free on both Android and iOS devices.

Once installed and connected to the NFZ100, the NNERGY app will let you monitor the battery health, battery level, battery voltage and other real-time battery information. Nitecore even offers a dedicated ‘Storage Mode’ within the app that will discharge the battery to 70% to help maximize its lifespan if it won’t be in use for some time.

Individual batteries can be labelled with three-digit identifiers to ensure you can tell them apart inside the app. There is even an option to upgrade the firmware of the batteries as Nitecore further develops its technology. Yes, you read that right, you might soon need to update the firmware of your camera batteries, not unlike you do your camera itself.

The NFZ100 batteries feature 2,280 mAh capacity, which Nitecore estimates is good for 500 still photos when shooting with the Sony a9. Voltage is 7.2V, giving it a power rating of 16.4Wh.

Other features include overcharge protection, over-discharge protection, overcurrent protection, over voltage protection and short-circuit protection. The batteries weigh 82.5g (2.91oz) and measure 52 x 38.7 x 22.5mm (2.05 x 1.52 x 0.89in).

The Nitecore NFZ100 doesn’t appear to be available to purchase through any online retailers as of now and no current pricing information is available. DPReview has contacted Nitecore and will update this article with more information if we get a response.

In the meantime, you can find out more information on Nitecore’s website.
