About six months
Official lab data, filled for about six months at a time,
It will change with the influence of the use environment and temperature (the colder the temperature, it will affect and reduce the use time of the battery),
The more times the doorbell is awakened (the more times the battery is used), the less time the doorbell is used (the detection range can be adjusted to change).
If the doorbell consumes electricity faster, please check the number of videos in the review, if the number of recordings is too much, it will naturally consume more electricity.
Five times a day can be used for about a month.
