Which battery does the Honeywell 5802WXT use?
If you have a Honeywell 5802WXT wireless panic button, the wireless transmitter is powered by a battery. You should not need to replace the battery very often as the battery that is included is a long-life lithium battery. In fact, with normal operation, you should get 4-7 years of battery life before needing to purchase a replacement battery. You will know when it is time to replace the battery because a low battery trouble signal will be generated along with the (2) digit zone number that corresponds with the zone you use to program your 5802WXT wireless panic button. If you have a wireless alarm control panel like the Honeywell L5100 LYNX Touch, the low battery trouble will be displayed right on the touchscreen display. If you have a VISTA Series alarm control panel with a Honeywell wireless receiver, the low battery trouble will be displayed on all of your wired alarm keypads. Also, if you have your Honeywell wireless security system monitored by a central station, the low battery signal should be reported to the central station so that an operator can alert you that you need to replace your 5802WXT battery.
When replacing the battery on your 5802WXT wireless panic button, you should only use a 2032 3V lithium coin cell battery. There are many battery manufacturers that make a 2032 3V coin cell lithium battery, but Honeywell states that you should use Panasonic or SENER CR2032 batteries only with ETL installations.
