Rechargeable battery
Yeah, the battery is very good.
You charge it and start using the camera for a long time.
The battery lasts according to the amount of movement in front of the camera.
If you install the camera in a place with a lot of people or animals passing by, it will activate the recording more frequently, thus using more battery power.
For an indoor application, it seems to "last forever," I put my camera in a room, and a week later, the battery was still with 35% remaining charge.
For indoor application it depends were the camera is installed.
If it's close to a gate where people don't suppose to come often, the battery can also last for an extended period, and you can use a solar panel to charge it up.
