300-03866, LCP500-4B Battery for Honeywell 300-03866, LCP500-4B, LYNXRCHKIT-SHA, OSA214, (7.2V, 3700mAh Ni-NH Battery Pack),

Installed this and appeared to work but later problem recurred within a month in ADT control panel. Eventually had ADT service come out and they said was a bad battery. They replaced it with one of theirs ($45) and now all seems to work fine. One month seems a short life for a rechargeable battery.

Purchased this battery two months ago for my ADT alarm panel and it has already begun to give a low battery warning. I wouldn't give it any stars if I could. This battery was a waste of money.

This battery was challenging to locate - I should have just started with Amazon,,,, It was delivered as promised (very speedy). It was easy to install (with the system directions leading the way.) The peaceful life of green lights returns! Thank you Amazon for always having what I need.

Works well with the Honeywell Lynx L7000. This is a larger battery than the original one which means longer run time. Remove the original battery and this one fits directly into the battery compartment. This batteries connector will fit into the factory pin connection. However you will have to use the larger battery pin as the factory battery uses the smaller one. The battery securement tab will also work with this battery, but you have to move it to the left which is the slot for larger batteries.

Arrived in great condition and was easy to install.

Worked like a charm. Alarm company wanted 65 to come out and replace a 1 year old dead battery. Doing it myself now.

It did it's work and still functioning. :) BUY IT!

Excellent fit and bigger battery than what came originally in our security panel.
