- NEEWER 2400mAh NP-FZ100 Replacement Battery, Rechargeable Camera Battery with USB Type C 2.5 Hrs Fast Charging Compatible with Sony A1, A9, A9 II, A7 III, A7R V, A7S III, A7 IV, A6600, A7C

I’ve never been the biggest fan of Neewer products—perhaps a lingering bias from their earlier reputation as a “cheap” or knockoff brand—but I decided to give these FZ-100 batteries a shot. With Sony’s OEM batteries priced at more than double, it was worth exploring a more affordable option. I’ve had good experiences with third-party batteries in my Fuji kits (notably from BM Premium and WasabiPower), but reports suggested that their FZ-100 equivalents often triggered a “non-compatible battery” warning on Sony bodies—a minor annoyance. I’m happy to report that these Neewer batteries work perfectly in both my Sony a1 and a1 II, even with the latest firmware updates (v3.01 and v2.01, respectively, released April 2025). In real-world use, they appear to offer comparable capacity to Sony’s official FZ-100s, with no error messages or compatibility quirks. Charging is equally flexible: the batteries work seamlessly in Sony’s OEM charger as well as Tilta’s 4-bay USB-C charging station. The ability to top them off via USB-C—whether from a power bank, laptop charger, or wall adapter—is incredibly convenient when shooting on location or traveling light. Overall, I’m pleasantly surprised. While I’ll continue to monitor long-term performance, these Neewer FZ-100 batteries have proven to be a reliable, cost-effective alternative—especially for those building out multi-body kits or looking to travel with backups.

This is actually my second Neewer USB-C direct-charge battery, and I’ve had great luck with them. My first was for a Canon R6 Mark I, and it lasted 3 years of constant use without any issue, so I decided to try this NP-FZ100 for my Sony A7C II. The battery fits exactly like the Sony original with no problems, is fully compatible with the camera, and even charges directly over USB-C without needing a dedicated charger—which is a huge plus for travel and convenience. In real-world testing, the performance has been excellent: at 91 shots it still showed 68% remaining (looked like ~300 shots total), but after longer use (294 photos with 56% left) it worked out to about 650–700 shots per charge, nearly identical to Sony’s OEM NP-FZ100 rating. It holds charge well, has been completely reliable for still photography so far, and for the price it’s an excellent value compared to Sony’s OEM battery. I’ll update this review if any issues arise, but given my experience with Neewer batteries, I’m confident recommending it.

Works great, no errors, holds a long charge so far! I love the USB-C port that I bought a second battery! once 1st is dead, I can hook it up to my portable charger and voila! very convenient when on the hike!

Higher quality than expected, Definitely work the price. Love the charge directly with USB-C. I think it is going to last.

With the Sony A7V it gives an error warning on the camera but seems to otherwise work. The charging port on the battery is convenient.

Fits the Sony body perfectly, holds a solid charge, and the USB-C charging option is a huge bonus—no extra dock or wall brick needed. Great backup or primary battery at a fraction of the OEM price, with zero compatibility issues so far.

For the price it works great, has decent battery life and does not give any warnings when using it with my A7S3, It can be charged in the Sony charger or with a USB C charging cable.

Really great battery. Just as good as the Sony batteries and does not have the issue of being unreadable in the newer Sony models looking to purchase more

Me ha sorprendido gratamente porque tiene una durabilidad igual o superior a la original de Sony costando 1/3. La estoy usando en una Sony A7 IV con el firmware actualizado a la ultima versión y no da ningún fallo de compatibilidad. Habrá que ver como evoluciona con el tiempo en cuanto a si pierde o mantiene su capacidad de carga. En un año aprox volveré a opinar.

Cette batterie fonctionne parfaitement sur mon Sony A7S dont les batteries étaient vieillissantes.

Recién la cargue y para poner a prueba, no se me descargo sin usarla, claro que está nueva y ese modelo de carga mediante cable.EXCELENTE.

Idealny zamiennik oryginalnej baterii do sony a6700, polecam

good choice!
