Works great!
This battery was just what I needed. Before you just put it in and connect it like any other battery, be sure to follow the steps for depassivation if your siren requires it or else the battery will not register and charge correctly.

Don’t waste your time and money
I tried 3 times to depassivate this product in my outdoor siren unit (each of my attempts timing out at 30 min). The strobe turned off followed by a single beep which indicates that the battery is dead or defective. Furthermore, after attempting to contact customer service, I received no reply.

Depassivated in under a minute. So it was a fresh battery!
So glad this battery is still available from the same supplier. Previously I had bought this one from them and it lasted more than 2.5 years: https://a.co/d/6e1Cj80 The new one I got depressivated in just about 30 seconds so it was fresh! Just as I did with my previous review of the one linked above, I will continue to come back and update my experience with this battery. Before finding this brand and seller, I had gotten very frustrated trying to source quality replacements for my outdoor siren. The included instructions were great to have included so I didn't have to dig up my directions for starting the depassivation cycle.

Works as stated
The battery works, but it was a year and 2 months old. The first one lasted 3 years.

ADT came to install this battery, which is NOT Working. After ADT tested battery is showing Dead with NO charge in this battery! DO NOT BUY THIS BATTERY. IT IS WASTED MONEY!

I bought this for my ADT SIREN, and it’s cheaper to buy here than from them. Thanks!
