One. What is the model number of the battery for the electronic door lock?
Fingerprint locks typically use 4 pieces of No. 5 alkaline batteries. The typical lifespan is approximately one year (actual lifespan varies depending on functionality, power consumption design, and usage frequency). According to industry standards for manufacturing anti-theft fingerprint locks, an emergency power supply interface should be included, which can be powered by an external 9V stackable battery.
Alternatively, you can use lithium batteries specifically designed for electronic door locks. These batteries can be charged and used for more than 12 months under ideal conditions, can be repeatedly charged without the need for replacement, and will only need to be replaced when the lithium battery is no longer functional. However, the overall cost of these specialized lithium batteries is higher.

First, follow the method described above to open the battery cover of the electronic door lock, then remove all the batteries from the battery compartment. Next, replace them with new batteries. It is crucial not to mix new and old batteries, as this can cause leakage and affect the normal operation of the fingerprint lock. Allow the fingerprint lock to operate normally for two minutes, then touch the battery with your palm. If the battery becomes noticeably hot, replace it with a new one until it is functioning normally.
Four. How often should the battery in an electronic door lock be replaced?
Currently, most smart door locks use batteries, and with normal use, they typically last for about six months. Some models with lower power consumption can last up to a year. Even when the battery is low, you don't need to worry. The mobile app will provide notifications, allowing you to replace the battery in a timely manner. If the battery is completely depleted, you can use a portable power bank to temporarily charge the device.
