Kastar Battery Replacement for Honeywell Ademco Genuine LYNXRCHKIT-SHA Lynx Backup Battery, 300-03866, LCP500-4B, OSA214, Lynx Plus, Lynx 5100 5200 5210 5300 7000, Lyric Keypad LCP500-L Controller

Works great with my system. easy to install- fit perfectly just had to plug it in. Priced great..arrived early too

It didn’t pay much attention to it. I put it on and my alarm work so.

Came fully charged and I installed it easily. My alarm panel was beeping and showing low battery. All is well

The wires are a bit short for an Ademco/Honeywell Lynx Plus. Just a few more cm of wire would have worked. I'm able to use this battery pack, but the wires cannot be inserted into the hold-downs that make them fold neatly when the panel is closed.

Unfortunately, I didn't get a chance to check this before my old battery seemed to resurrect itself, but the new battery I got simply does not charge at all. I kept it plugged in for days and the panel consistently reported low battery. I finally checked it with a multimeter and it is completely dead. I also checked the charging terminal on the panel itself to make sure it was actually not dead and that was not the case. The battery is simply dead on arrival. I realize it is my fault for not checking this sooner so I could return it, but nevertheless. It is simply an unusable and dead battery.

My alarm system had a “low battery” alert and it was driving me crazy. Every 3 hours it would start beeping every few minutes nonstop until I hit the disarm button, waking me up throughout the night and causing the monitoring company to call me to alert me. I was waiting for the alarm company to call me back about a replacement when I googled the barcode number, found this, ordered, received and installed it in less than 24 hours. It was extremely easy to install, just plug in. It is larger than the original one but that was no issue, my panel is set up to accommodate both sizes. It took a few hours for the low battery alert to go away but it’s gone now.

Had to replace the internal batter in my Honewell Lynx that I did not know existed until my alarm started beeping constantly. The battery fit inside the unit will and corrected the issue.

Reliable. 3 years now.
