Valuable Information on Smart Lock Batteries
What are the Different Variables Affecting Battery Life
When it comes to consuming battery life, connection integrations prove to be the biggest culprits.
While other variables also exist, Wi-Fi, Bluetooth, Z-Wave, and Zigbee are the most common connection integrations affecting battery life.
Many of us are aware of Bluetooth and Wi-Fi but aren’t familiar with Zigbee or Z-Wave. Simply put, they are languages or wireless protocols used in smart devices for various home automation functions.
The degree of battery consumption, however, varies for the different connection integrations. For instance, Wi-Fi requires far more power than any other connection integration. While Bluetooth consumes comparatively less power but we all know about its range limitations. Both Zigbee and Z-wave use very low battery power.
In normal circumstances, a battery-powered device is not considered feasible when a Wi-Fi connection is involved due to its high power consumption. Smart locks are among the few exceptions, though. Given the improved standby features in the latest Wi-Fi routers and the advancements in battery technology, many battery-powered smart lock devices perform incredibly with Wi-Fi connection.
Why Prefer Alkaline Batteries Over Lithium Batteries?
Lithium, old rechargeable batteries are often subject to undesirable operation. For instance, they offer a very steep discharge curve at the end of their lives. This means the will give little or no warning before the batteries die. This increases the chances of getting locked out of your home, and you’ll have to resort to the traditional way of entry, that is, use a backup key to enter your home.
Therefore, in the case of smart locks, you should always use premium alkaline batteries, all of which give low battery warnings well before the battery dies. Many of these batteries feature gradual power discharge and alert when 20% of life is remaining, providing ample time to replace the batteries before they are at the end of their life.
Ideally, the users should replace the batteries immediately to ensure continuous, reliable operation, when given the low battery warning. New and unused alkaline batteries are best for replacement.
