What type of batteries should I use?

Schlage recommends using a premium alkaline battery for all electronic locks. The only brand recommended in Schlage locks is Duracell Coppertop. We do not recommend off brand, store brand or Energizer. Engineering have done multiple tests to determine which brands do work best in these locks. 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.
