How Long Does a Smart Lock Battery Usually Last?

2024-05-17

The durability of smart lock batteries is affected by multiple variables, including the type of battery (such as common dry cell batteries and lithium batteries), the type of door lock (semi-automatic or fully automatic), the frequency of daily use, and whether the door lock has advanced features (such as integrated cat-eye cameras, face recognition, etc.). These factors together determine the length of battery life, which usually ranges from a few months to a year and a half.

When using dry cells as a power source, the life of smart locks can usually last about half a year under normal usage frequency. If high-quality batteries are used, the life may be longer. When the power drops below 3.5V, the smart lock will automatically sound an alarm to prompt the user to replace the battery.

On the other hand, for smart locks powered by lithium batteries, the battery life can be roughly 1 to 2 years when used 15 to 20 times a day.

For some fully automatic smart locks, they can run stably for 6 to 10 months on a single charge.

Specially customized smart locks, such as those using 4-8 semi-automatic batteries, can usually last for 12 to 18 months.

In order to keep the smart lock working continuously, it is recommended that users check the battery power regularly and replace or recharge it in time when the power is low. In an emergency, if the door lock runs out of power, the user can use a mobile power bank to temporarily charge the door lock through the emergency interface. In addition, in order to deal with emergencies, most smart locks are equipped with spare physical keys in case of emergency.
