Normally, an alarm system relies on a plug-in transformer to receive consistent power. But if the electricity goes out, then the system will need to rely on a different power source to remain powered on. That is where a backup battery comes into play. Every alarm system should have a backup battery so that it can remain powered on during these unforeseen circumstances. And the Honeywell LYNX Touch System is no exception.
A Honeywell LYNX Touch Panel actually has three backup battery options. The LYNXRCHKIT-HC is the high capacity battery, and it serves as the middle tier option. It is not the battery that originally comes with a Honeywell LYNX Touch Alarm System. That is actually the LYNXRCHKIT-SC Standard Capacity Battery. However, the LYNXRCHKIT-HC High Capacity Battery connects with the same internal port on the circuit board. These batteries are all rechargeable and slowly store power while the panel is running on AC power.
To replace the battery, a user needs to open up the panel and unplug the current battery. There may be cover keeping the battery in place, and you would need a screwdriver to remove this cover. After taking out the battery, you can connect the new one and secure it in the same place. Then close up the panel, and result using your system like normal.
There is also super high capacity battery option for the Honeywell LYNX Touch Systems. This battery is called LYNXRCHKIT-SHA, and it can keep the system running for up to 24 hours at a time. Unlike the standard capacity and high capacity batteries, the super high capacity option connects to a slightly larger port that is also found on the main circuit board.
Even though there are two ports, you should never try to use more than one battery with the system at any given time. In other words, don't try to use a super high capacity battery alongside either a standard capacity batter or high capacity battery. Using multiple batteries can overload the system and cause it to experience damage or work improperly.
The LYNXRCHKIT-HC will provide a minimum of eight (8) hours of backup power when used. This is considerably longer than the four (4) hours of backup power provided from the LYNXRCHKIT-SC. The battery should last for several years, but it will eventually lose its ability to store a charge. At that point, it will need to be replaced with a new one. You will know that your battery needs to be replaced because there will be a low-battery warning that won't clear even after several hours of recharging on AC power.
