Super easy to install. Saved $100 by ordering and installing it myself verses a service call. A five minute job, just follow the simple directions.

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

What a waste of time. This battery has a weird feature that requires getting it out of its storage mode. That took way too much time, and the process didn’t work after a long wait, just as the instructions warned. To return it, like it said to do, was a hassle because it’s a lithium battery.

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.
