UPDATE: K&F reached out to me and asked for more info about the failure. I told them and sent a video showing the dead battery. They are sending me a replacement battery, even after a year! That’s great customer service I changed my rating to 5 stars based on the overall battery quality AND the amazing customer service! I’m very impressed. I'm writing this review a year after purchasing these batteries. They initially worked very well. No problems at all. They charged quickly and fit the camera perfectly. However, at a recent shoot, I put one of the charged batteries in the camera, and it was completely dead. I tried charging it when I got home, and it was still completely dead. The other two batteries are still working well. For the price, I'm still ahead compared to the OEM cost.

Great batteries, not as long lasting as OEM Sony but great for the price!

Great purchase! I just got my Dad's Sony A7riii and didn't realize that the batteries were different than my a7rii until the night before I fly to Europe. Luckily I got overnight shipping and these batteries worked great! It did charge the Sony battery as well. It has an indicator for each of the three battery slots. Battery life seemed pretty good too, compared to the factory Sony battery. There was a USB connection to the charger so make sure you have a brick to connect to the wall outlet to the old USB 2.0 port. Great purchase!

These batteries are perfect replacements! I have been using them every week and they last just as long as my Sonys. Great product

Only used them once so far but they do what they’re supposed to…

While they do not seem to last as long as my Sony batteries, these batteries are inexpensive and make for a good back up. I always keep several charged and available.

Took the batteries for 5 hour-long time lapse and they did as god as the original ones. no complains - the charger is great, i have no issues at all.

Works great. Triple the time saved when charging batteries.

Brilliant

Ho acquistato questo kit di batterie per la mia Sony A7III già conoscendo il brand, avendo in passato preso altri prodotti fotografici dello stesso marchio sempre con ottimi risultati. Anche in questo caso la qualità non ha deluso. Le batterie hanno una capacità praticamente identica a quella dell’originale Sony: la durata è molto simile, forse leggermente inferiore, ma avendone tre a disposizione si riesce a coprire tranquillamente anche sessioni fotografiche o video piuttosto lunghe senza alcun problema di autonomia. Molto utile la basetta di ricarica, ben costruita e compatta, che permette di caricare più batterie contemporaneamente. È dotata di un piccolo schermo retroilluminato che mostra chiaramente lo stato di carica di ciascuna batteria, spegnendosi automaticamente una volta completata la ricarica. I tempi sono in linea con l’originale: circa 4-5 ore per tre batterie contemporaneamente; se invece se ne ricarica una sola, i tempi si riducono perché tutta l’energia viene convogliata su una batteria soltanto. La qualità costruttiva è ottima: non ho riscontrato problemi di compatibilità, surriscaldamenti o malfunzionamenti, e le batterie vengono riconosciute senza difficoltà dalla fotocamera. Considerando che al prezzo di questo kit si riesce a malapena a comprare una singola batteria originale Sony, il rapporto qualità-prezzo è davvero eccellente. Per chi scatta spesso, viaggia o lavora in esterni e vuole avere sempre un set di batterie affidabili, è una soluzione che consiglio senza esitazioni.

Batteries et chargeur de qualité. Les batteries NP-FZ100 remplace parfaitement les modèles d’origines Sony pour une fraction du prix. Elles maintiennent la charge aussi bien et elles permettent de faire fonctionner mon appareil photo aussi longtemps que les batteries d’origines. Je recommande!

Ich habe die K&F Akkus für meine Sony A7III gekauft und bin absolut begeistert von der Leistung und der Qualität. Hier sind meine Erfahrungen: Langlebigkeit: Die Akkus halten wirklich lange durch – viel länger als die Originalakkus. Bei meiner letzten Fotosession konnte ich ohne Probleme den ganzen Tag fotografieren und filmen, ohne dass der Akku leer war. Das ist besonders wichtig für mich, da ich häufig längere Shootings mache und keine Lust habe, ständig den Akku wechseln zu müssen. Kompatibilität: Die Akkus passen perfekt in meine Sony A7III und funktionieren genauso gut wie die originalen Sony-Akkus. Kein Problem beim Einsetzen oder bei der Erkennung durch die Kamera. Ich hatte bisher keinerlei Probleme mit der Kompatibilität, was für mich ein großer Pluspunkt ist. Preis-Leistungs-Verhältnis: Für den Preis erhält man hier eine ausgezeichnete Leistung. Die Akkus von K&F sind deutlich günstiger als die Originalakkus von Sony, bieten aber eine vergleichbare oder sogar bessere Leistung. Wenn man wie ich viel unterwegs ist und mehrere Akkus braucht, ist dies eine super kostengünstige Alternative. Ladezeit: Auch die Ladezeit ist beeindruckend. Die Akkus lassen sich schnell aufladen, sodass ich nicht unnötig viel Zeit mit Warten verbringe, bevor ich sie wieder in die Kamera einsetzen kann. Fazit: Die K&F Akkus für die Sony A7III sind definitiv eine sehr gute Wahl! Sie bieten eine zuverlässige Leistung, lange Laufzeit und sind preislich attraktiv. Ich werde auf jeden Fall bei K&F bleiben und kann diese Akkus jedem empfehlen, der eine zuverlässige und preisgünstige Alternative zum Originalakku sucht.

Charge is slow… and the capacity seems lower.. it is good for the price but really not ideal on a serious projects. Mid interview all of a sudden the battery is draining so fast that you start to sweat!
