A variety of factors (shelf life, openings per day, environment, battery brand, lock settings, etc.) will determine how long your lock operates on a set of batteries. In average conditions, you can expect a minimum of 100,000 openings for E-Plex 2000 models with 3 “AA” Alkaline Batteries. A Low Battery condition is identified by a flash of both red and green LEDs when a valid access code is entered, and the lock will still give access. When the low battery condition is observed, the batteries should be replaced as soon as possible. |
