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.
