I have a sony a7iv and a sony FX30 and both of them in the latest version, i have ZERO issues with these batteries and every time i meet someone with a sony camera i always recommend these batteries, they're great in price so you actually get way more for your money!when i need to charge them it makes it super easy that i could use a USB C charger to charge them in a couple of minutes, they last so much longer than the sony OEM batteries!

Very pleased with these off brand batteries. They can be charged with a usbc cord directly and I don’t get a message in the camera indicating they are not a Sony battery. Nice to eliminate extra charging devices when I travel since it can be charged directly.

Works great on my Sony a7CR with latest firmware. No error or warning messages. So far no issues with duration or charging, plus the convenience of being able to charge directly from USB-C makes it so much better than having to bring along another charger. This is what the Sony original batteries are missing.

Best aftermarket batteries ive used, hold charge well. Better then smaller ones for a7rii. Cant beat price over original sonys. Definitely worth it. Fits in camera no issues. Performs as expected without warnings on screen.

Despues de llevar probándolas unas semanitas,tengo que comentar que la duración está un pelín por debajo que las originales.Lo bueno de estas baterías a diferencia de otras no originales es que con estas no te sale el mensajito de "batería no original".Así que de momento perfectas para mí Sony A7M4.Veremos cómo envejecen.

Genau was ich gesucht habe. Einfache Handhabung beim Laden über Powerbank und Solarpanel.

Haven’t used these batteries enough to determine how long they will last, but they work fine in my A7iv. The USB-C port is great for charging.

It has decent capacity but you get inaccurate indication on the camera, and it fluctuates between full and empty. Won't charge in the original Sony charger, but works with the third party charger, plus it has the built-in USB-C plug. I bought these for a long backpacking trip, and they worked for that purpose and are a lot cheaper than the Sony batteries.

Ragazzi se cercate una batteria con prestazioni superiori alle originali sapete quali scegliere !Mi sono meravigliato della loro durata ! Normalmente ho sempre usato batterie di altri marchi di concorrenza e pur dichiarando durate simili alle originali , non arrivavano mai al pareggio, invece qui i 2600mha sono reali e vi danno quella tranquillità in più quando siete fuori per eventi o altro!Inoltre il quid in più lo fa il connettore usb c che permette di caricarle con qualsiasi caricabatterie cosa comodissima quando ci si scorda l’originale a casa

Love these batteries, absolutely life changing. I no longer need to bring a battery charger when I travel and I can charge them with a power bank whilst I'm out and about. Their capacity is larger than the original Sony batteries so it's a no brainer! Confirmed they work with Sony a7IV and a7c
