ZZcell® High Capacity Battery Compatible with Honeywell Alarm 300-03866, Lyric Controller, Lyric Keypad LCP500-L, LYNXRCHKIT-SHA, OSA214, LCP500-4B, 3700mAh (Please Check Part Number Before Purchase)

I priced this battery At a local battery store. This one was half the cost and works perfectly well and for the length of time expected. This is my 2nd time purchasing.

Was not the correct fit.

This battery was a perfect fit physically. But I did not pay attention to the connector. It comes with a three position plug and uses two wires. My L3000 uses a two position connector and two wires. I don't believe the product should claim to fit an L3000 when it won't. To save time I just swapped the connectors and so far all is OK. So be careful and verify your connectors before you order.

Nice quality and fast shipping

Hardest part about replacement was removing the wire cover the installer used to dress up the install. After that, replacement of the battery was very simple. Battery is an exact replacement. The panel recognized it without any error messages. Love it when a plan comes together.

Perfect fit in ADT alarm

it was for my home alarm-all set!

The plug was wrong, had to solder the old plug on the leads so was a more difficult installation than simply plug in
