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!

Lasts about four years
As it turns out I was replacing an identical battery. At the end of four years the old battery was still working with my alarm system but I got a message that the battery needed to be replaced. When I checked it, the charge was down to 12 volts. Unfortunately, I don’t have a device that can use an oversized battery that runs on 12 volts so I will have to send the old battery to recycling. The new replacement battery is running fine.

IT WORKS JUST LIKE IT SHOULD!!
Not a glamorous or exciting purchase but my home alarm system is hard wired and it started chirping at the most inopportune times, like the middle of the night. I found the battery and matched it up to this one on amazon and attached it upon delivery, and VIOLA! It stopped chirping and now the alarm is back on!!The price was right and it came quickly and all is right in my world. If you need a battery like this, this is the one you should get!

Good Value
Purchased to be our on hand back up to rotate with the primary so we are always share to have a good battery in our alarm system and another fully charged ready to swap out just in case. We found that because these are rechargeable and so durable, few stores carry them on the shelf. NONE of the big chain hardware/DIY stores do, and they can't get you one as quickly as Amazon. So, if you don't have a Batterie/Bulbs+ store near you like we don't, and you don't want to pay their much higher price, having a backup from Amazon is a good option.

Just like the one it replaced.
My alarm battery died. I ordered this odd ball battery and it was delivered The next day. Popped it in to replace the old one and it works perfect.
