Door bell batteries

I charged my battery till 100%. Put it in the foor bell. Its also attached to a hard wire . Now its at 92% after 1 day. It should remain at 100% regardless of what is going on. I thinks it faulty? ???

Hi @juliaolivia. Hardwiring a battery powered Doorbell doesn’t provide continuous power, it provides a trickle charge to the battery. The Doorbell is still powered off the battery directly rather than the doorbell circuit. With that in mind, the battery may drain more quickly than it can be charged via the wiring.

Various factors can affect how quickly the battery drains, including the level of activity recorded and the weather. We have some information on battery drain here. Additionally, very cold weather can impact the performance of lithium-ion batteries, such as the ones used in Ring devices. I hope this information helps.
