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 | Compatible with A1 A9 A9 II A7 III A7R V A7S III A7 IV A6600 A7C, Rechargeable Camera Battery, USB C 2.5 Hrs Fast Charging

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.

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.

Excelente It's just like the original camera battery, and best of all, it can be charged directly.

I use this battery for my Sony a6700. I really like it as the battery holds a good charge and has the added benefit of having the USB-C port right on the end, which makes it super easy to charge (not needing to bring an extra charger on a trip is great). Combining this battery with the OEM battery allows me to charge on battery in the camera and one outside the camera, without needing anything other than two USB-C cables. Build quality is good. I recommend.

Excellent back up battery. Not as long lasting as the genuine one, but certainly good enough. Being able to charge it with a simple USB-C cable is helpful when traveling.

Lasts longer than factory battery. Usb-c charger makes it really convenient and I don’t bother to bring the Sony charger when traveling.

Have used a number of times. Works well in my Sony cameras, seems to hold a charge well, is rougly the same weight as the OEM battery and easily distinguishable by the khaki color and USBC receptacle for charging without carrying a separate charger. Roughly half of my batteries purchased since 2021 are Neewer ones, and though I have not compared their charge life to my OEM batteries they seem to hold the charge almost as well as the OEMs and have not failed or caused damage to my camera bodies as some have reported. Incidentally, batteries should always be charged in a separate charger, and never charged in-camera. Should any battery suddenly have a problem it could swell and be difficult or impossible to remove from your camera body.

Great Price, However the battery life leaves something to be desired, I love the fact that I can charge it in the usb c charger in my car but make sure you get a few of these to offset the life of them

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!

Hält genauso lange durch wie das Sony-Original, und dank dem USB-C Anschluss brauche ich kein zusätzliches Ladegerät (man will ja auch nicht einen Akku nach dem anderen in der Kamera laden), kann den Akku sogar unterwegs an einer Powerbank / - Station aufladen! Tolles Produkt, sollten ALLE Akkus haben!
