For my Canon R10 I was looking for alternative batteries that I could use in an emergency when my original Canon batteries were empty. Since I usually get through the day with the original batteries, I didn't want to buy an expensive battery and that's how I came across the batteries from "K&F Concept".

The batteries are delivered in a cardboard box, so there is no unnecessary plastic. The delivery includes the following items:
- Charger
- USB cable type
- 2x batteries (compatible with LP-E17)

The batteries are inserted upright into the charger. This requires a bit of force at the beginning, but after charging it a few times it becomes much easier. The charging process is indicated by two LEDs. Which changes from orange to green when fully charged. The charging process is completed in an acceptable time. However, the batteries then have a slightly shorter battery life than the original batteries.

Inserting them into the camera works without any problems and the batteries fit in well. Unfortunately, the camera does not recognize the batteries correctly, so the charge level cannot be displayed correctly. This means that the camera may simply switch off at some point. You should be prepared for this and replace the battery early.

The item is relatively expensive, but overall it still costs less than an original Canon battery. I would therefore recommend buying it.
