    Replaced a defunct battery backup in my home security system. Don’t know what the longevity of this battery will be, but previously I was getting about 5 to 6 years of battery life. Priced reasonably and fit right in existing enclosure.

    Working great for my Honeywell Vista 20P from Protection One. Existing connectors on the panel popped right on. It is lower capacity than what I had originally from the security company but I’m not too concerned and it’s no fault of this battery.

    Its pretty simple. …your battery died on the alarm system…The security company wanted $$$$$$ to come and basically replace a battery. …Great buy…saved serious $$$$$…no brainer plugging it in…works fine ….will definitely buy again …
