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.

Having three batteries in rotation completely eliminates downtime. ⸻ 🔌 Upgraded LCD Charger – Huge Plus The upgraded LCD charger is one of the standout features of this kit. • Clear digital display shows charging percentage • Dual charging slots allow you to charge two batteries at once • USB-powered, making it easy to charge from wall adapters, power banks, or even a laptop The LCD readout is much more informative than traditional blinking-light chargers.
