What Type of Battery Fits a Honeywell 5800 Infrared Motion Sensor?

The type of battery that fits a Honeywell 5800 Infrared Motion Sensor is usually a CR123A battery. This is the battery that is used with a Honeywell 5800PIR, a Honeywell 5800PIR-RES and a Honeywell 5800PIR-COM. The one exception is the Honeywell 5800PIR-OD, which uses four (4) AA batteries.

A wireless motion detecting sensor needs a battery for a few different reasons. For one, the passive infrared (PIR) sensor itself requires power to complete the motion detection process. Secondly, the wireless sensor also needs power to send wireless transmissions to the panel. A battery allows these motion sensors to function without using a wire to feed power from a wall outlet or a panel. The Honeywell 5800 Motion Sensors are no exception to this rule, and each of these sensors relies on battery power for basic operation.

Most of the Honeywell 5800 Motion Sensors use a single CR123A battery for power. This is commonly known as a camera battery for its popular usage in cameras. The Honeywell 5800PIR, the Honeywell 5800PIR-RES, and the Honeywell 5800PIR-COM all use this type of battery. Each of these sensors has an expected battery life of up to ten (10) years. When the battery is low, you will need to replace it with a new one. This can be easily done by the end user. Simply open up the sensor, remove the old battery, safely dispose of it, and insert a new one. For best results, lithium CR123A batteries should be used.

There is one PIR motion sensor from the Honeywell 5800 Series that uses a different battery. This is the Honeywell 5800PIR-OD, which is designed specifically for outdoor use. This particular motion sensor uses four (4) 1.5V AA batteries. This motion sensor has an expected battery life of four (4) years with typical use. This means that you will most likely have to replace the batteries more often with this motion sensor. Again, it is recommended that you use lithium batteries for best results.
