New Camera Argus Eco

Hello, I am the owner of a new Argus Eco 2 Camera and I have a few questions about it:
1) First of all I have fully charged the camera via USB. Then I installed it outside and connected a solar panel from Reolink. After now 5 days of use the battery has dropped to 79 percent. The light on the back of the camera is green. We had 2 sunny days the last days and today. However camera reamains with 79%. Is that still normal? Or does the sun always need to shine to get back to 100 percent when the solar panel is connected? How can I see the solar panel is recharging? Im sure its correctly connected. An SD card is also installed.

2) Can I, if I want to charge the camera via USB, remove the battery from the Argus eco separately and charge it separately or must the whole camera always be removed?

3) Does the camera delete/overwrite old recordings from the SD card automatically when the card is full? Is it possible to manually delete old recordings from the SD card?
