Battery charge required though online

I’ve an indicator saying my battery is at 21% but the doorbell is online via a transformer…?? Advised to charge it up but why should I have to if online. Everything is working ok…

Hi @Steve143. What specific model Doorbell do you have? When hardwiring a battery operated Ring Doorbell, the hardwire works as a trickle charge that basically maintains the charge that your Doorbell currently has. This depends on the number of events you have per day. If there is an excess of 35 events per day, this could cause your Doorbell battery to drain faster than the hardwire can charge it. Let me know if you have anymore questions.
