  • Lithium Batteries

Lithium batteries are composed of Lithium and carbon and hence have a higher lifespan than an alkaline battery. But there are several drawbacks of these batteries such as, expensive and degrading quickly.  

Factors Affecting Battery Life of Smart Locks

Several factors affect the battery life of an electronic door lock. Let us understand the one by one:

  • Quality of the Battery

Among these Bluetooth is the least favorable option as it requires a person to be around 300ft from the lock to connect. Moreover, they use low frequency and therefore do not consume much battery power. Therefore, battery life can work around 10-12 months.  


The second mode of communication is Wi-Fi. They are a much more advanced mode of communication and their sphere of influence is larger than Bluetooth. It allows you to connect to your lock from anywhere. But there is a drawback i.e. consumes more battery life. And therefore the battery life span is around 2-4 months. 


Z-waves are somewhat the latest mode of communication. They combine both Wi-Fi and Bluetooth. It deducts the disadvantages of both modes and only draws positive notes from them. Battery life lasts around 12 to 18 months. 

  • Frequency of Use

Another important factor is the frequency of use. The more you will use it the more power it will drain. The number of times you will lock and unlock the door will affect your battery’s life. 

  • Weather

Weather also affects the lifespan of the battery. Some batteries brain faster in particular weather while some in other weather. Therefore before purchasing any battery you should look at the temperature susceptibility.
