The Honeywell K0257 is a battery backup for the Honeywell 5800RP wireless repeater. Each 5800RP wireless repeater includes a K0257 rechargeable battery but after time you may need to replace the battery pack as all batteries eventually wear out. If your 5800RP no longer works when there is a power outage, simply replace your existing battery backup with a new K0257 battery.

The K0257 battery backup is actually made up of five 1.4V nickel-metal hydride batteries with wire leads. The five AAA NIMH batteries are encased in a green cover making up the entire K0257 rechargeable battery pack. With a new K0257 battery backup installed, a Honeywell 5800RP wireless repeater will work for up to six hours without AC power. Once primary power is restored, the battery backup will automatically recharge so that it is ready for the next power outage. Over time and after many charges, you will notice that the six hours of standby power will begin to diminish. Eventually, the 5800RP will no longer work when AC power is removed and you will have to purchase a new K0257 battery backup.

The Honeywell 5800RP does supervise the battery and will send a low battery signal if the K0257 battery backup drops voltage. The low battery threshold is between 6.5VDC and 6.2VDC. The battery status is checked approximately every hour. If your 5800RP does lose power and the battery is drained, a low battery trouble will be reported to your Honeywell wireless security system and it may take up to twelve hours for the K0257 to fully recharge. Once the battery pack is recharged, a low battery restoral signal is sent to the security system.

Myface Yourbook, thanks for the response. This system is in my rental property. As soon as I'm able to get my hands on it, first I'll check to see how I programmed the darn thing, then I'll do as you say and just disable the zone. You make a good point on loss of power. Best regards, Banner Ridge
So sorry for this late reply. The email associated with this account was locked and it was hell to unlock it and I've been busy. This was a DIY project and I did the install myself. I can't remember how I programmed it. I remember asking you for advice and followed what you said. You've been immensely helpful to me and I'm forever grateful. This system is in my rental property and my tenants constantly get calls on this stupid thing. I can check the programming because no way I can remember how I did it.
As Sterling said, disable that zone. Dont need it its a UL thing. I spent money on two replacement batteries from different manufacturers and they will not take a charge. That means its a 5800RP bug. Think about it. If you lose power, there will be many other warnings and the RP wont help anyway.
Hi Banner. You actually don't need any zone programming to use a 5800RP. It sounds like your company did add a supervision zone for the 5800RP so that you'd be alerted to issues with the 5800RP (power loss, low battery, etc). There are two ways to program that if you do want supervision so do you know if they have 1 zone or 2 zones setup for supervision as that will give us a better idea of how to troubleshoot your issue. Also, did you see we offer low-cost, no-contract monitoring plans at We are experts on your system and the Honeywell products and as long as you aren't under contract now, it would be easy to switch to us and I'm confident we'd be able to solve your issues for you. I'm assuming they aren't being as helpful as you'd like if you are coming to us for support so please do let us know if you are interested in switching.
One year ago I installed a Honeywell 5800RP to my LYNX Touch 7000 control system due to signal problems. It helped immensely. However, I'm already on my 3rd battery pack on this thing. The 5800RP is plugged into an AC socket, but for some reason, the battery pack continuously causes the 7000 to report battery trouble to the security monitoring company and I get calls on battery trouble. I thought the battery pack was only supposed to be a back up and not for operation? Any help or suggestions would be greatly appreciated on this. Best regards, Banner
