In a wired stick-up cam with a battery backup, does the battery recharge?

Just purchased the indoor/outdoor WIRED Ring Stick-Up security camera. I added the optional battery backup. I fully charged the backup battery before inserting it into the camera. My question: Should I have a power failure and the backup battery is used for a long period, once the main power returns, does the backup battery recharge inside the camera? Or, must it be removed and manually recharged? For that matter, does the wired camera "top off" the battery periodically and keep it charged? Thanks! BTW, my friends are stunned at the quality of the video and especially the night video. It really is amazing. A great investment.
