Leading Brands and Models
The Schlage Connect Smart Lock, known for its durability and robust security features, sets the standard for battery efficiency. Operating on 4 AA alkaline batteries, it is expected to maintain power for up to two years, accompanied by an early warning system to alert users before batteries are completely drained. This enduring battery life can be largely attributed to its use of Z-wave communication protocol, which is optimized for low power consumption while maintaining a strong, secure connection.
Other smart locks in the market also offer impressive battery life, generally ranging from one to two years, with the type of connectivity – such as Bluetooth or Z-Wave – being a major determinant.
WiFi-connected smart locks, however, tend to have a shorter battery lifespan, often requiring battery replacement every 1-3 months.
Consumers have the option of using lithium batteries for some models, which may extend the battery life further, making the product even more appealing for those seeking a low-maintenance smart home solution.
Some of the leading brands with models known for long battery life include:
- Schlage: Examples are the Schlage Connect Smart Deadbolt and Schlage Encode Smart Wi-Fi Deadbolt.
- August: Known for the August Smart Lock Pro.
- Yale: Offers models like the Yale Assure Lock 2 and Yale Assure SL.
- Kwikset and Ultraloq: Also high on the list with multiple offerings in the smart lock technology space.
In terms of battery life, the Schlage Connect Smart Deadbolt (BE469ZP) boasts up to two years on a single set of 4 AA alkaline batteries and features a low battery warning system.
