Sony NPFZ100 Z-series Rechargeable Battery Pack for Alpha A7 III, A7R III, A9 Digital Cameras black

Cheaper off-brand batteries usually work well for a little while, then die out of nowhere (often at the worst times). Meanwhile my original NP-FZ100s from 2018 are still running strong, seven years later. Buy OEM when it comes to these batteries

High capacity well constructed brand new battery. Perfect for Sony Alpha A7Riii, not for Sony A7rii models.

Perfect and durable

This battery cost more than the aftermarket brands but it is worth it.. I have never had a problem we with my camera shutting down in the middle of a shoot using them.. I do use a Sony battery grip and I can shoot 2k+ pictures per charge.. I'm a sports photographer and they is most helpful .. These batteries last 5 years or longer.. I have tried the aftermarket batteries years ago just to save a little money., but aftermarket batteries have issues.

As always a dead battery on delivery, a easy slow, TRI charge to care of it.Great product just can't leave the battery it the camera when not in use. .

These are good batteries but pricey. There are cheaper ones out there that are just as good. But you roll the dice with those. The peace of mind using these was worth the extra price in my opinion.

Bought used and it works great, basically like buying new.

I am satisfied with this battery based on a side-by-side comparison to the OEM product that came with my Sony A7Riii. Even though the genuine Sony option costs more than third-party options, the cost is far less than the repair bill to remove a swollen battery from my camera body. Battery life & time to charge is identical to the battery which came with the camera.Between knowing what I can expect from my backup battery on long shoots & reduced risk of damage to the camera body, I am happy with this purchase. Considering the cost of the camera body, I prefer the peace of mind not risking my equipment to potential damage by a sub-standard battery.*One thing to note – The packaging quotes a 79% remaining battery life out-of-the-box… (see footnote in review photos) My copy arrived totally depleted. I’m not sure why Sony prints this “79%” on the packaging but temper your expectations when opening the package and hoping to put a charged battery in your camera. Plan on fully charging it prior to first use.
