Can lithium AA batteries be used in the Defiant keyless entry deadbolt?

The Defiant keyless entry deadbolt‘s instruction manual specifically mentions using Alkaline batteries. This is because different types of batteries, such as Lithium and Alkaline, deliver power in slightly different ways, and the device is designed to work best with the type of power delivery that Alkaline batteries provide.

While Lithium batteries usually provide longer life than Alkaline batteries, they also have a slightly higher voltage, especially when fresh. This could cause issues with electronic devices not designed to handle that extra voltage. In some cases, it could damage the device or reduce its lifespan.

Furthermore, using a different type of battery than what’s specified in the device’s instructions could potentially void the manufacturer’s warranty.

Therefore, it is generally best to stick with the manufacturer’s recommendations for battery type to ensure your device’s best performance and longevity. In this case, use Alkaline batteries for your Defiant keyless entry deadbolt.
