The Yale Digital Door Viewer Memory Plus 4500 is powered by 4 AAA batteries and designed for energy efficiency. Thanks to its automatic shut-off feature after 10 seconds of use, the device can typically last between 2 to 6 months, depending on how frequently it's used. If you are experiencing significantly less than this, please check the points below.
- Avoid using rechargeable batteries as these typically deliver a lower voltage (1.2V vs. 1.5V for alkaline), which will impact device performance and battery life. Additionally, they can be sensitive to cold temperatures, so if your device is installed in an unheated space like a shed or garage, winter conditions might affect reliability.
- Damage to the cable which runs from the camera and into the viewer could also impact battery life. Inspect this to ensure that it has not be pinched, trapped or damaged.
