What type of batteries should I use in my Schlage Lock?

Schlage recommends using a premium alkaline battery for all electronic locks. The brands recommended and tested in Schlage locks is Duracell Coppertop and Energizer STD alkaline batteries. Energizer MAX batteries offer challenges fitting into the battery tray within the lock, and batteries can come ajar from the battery terminals in the tray.  

We do not recommend off brand, or store brand batteries. Engineering have completed testing to determine which brands work best in Schlage locks and meet the desired and published battery life. Lithium, or rechargeable technologies may cause undesirable operation. Our smart and electronic locks are equipped with low battery warnings. When presented with this warning, it is best to replace your batteries immediately to ensure continued, reliable operation. When replacing the batteries, it is best to use new and unused alkaline batteries.

 * Undesirable Operation:  At the end of life for lithium batteries there is a very steep discharge curve.  This means that when the batteries do reach an exhausted point, there will be little or no warning. This increases the likelihood of a lockout condition where the mechanical backup key would need to be used.  Alkaline batteries have a more gradual power discharge, so when they are at 20% life remaining, the lock can provide alerts (if programmed to do so) and local feedback (blinking red light) providing ample time to change batteries before they are at the end of their life.
