Great Price and Easy to Install
My alarm battery was low and I kept on getting automated phone calls from the alarm company to replace and call to have it replaced. We are all hooked up to the same system in my HOA and my neighbor said don't have them replace it , you can buy it and do it yourself at a fraction of the cost. As a senior, I was hesitant, but it was so easy to replace! Alarm system works great and I saved a load of money! Plus no installation fee because I did it!

Great battery as advertised
Needed this for my home alarm system. Installed and within about 3 hrs. it was fully charged and my system returned to normal. I would definitely recommend to you and buy again.

Battery replacement for home alarm system
The battery that came with my home alarm system lasted 7 years. This replacement battery has lasted less than one year. Built in obsolescence in end stage captalism. Ugh. BUT I called the CASIL company and an actual human being picked up the phone! This company is honoring the one year warranty and mailed me a new battery at no charge. Great customer service! My five star rating is based on my lowered standards for how long a battery can be expected to last in this current age and the excellent customer service.
