Works in Home Alarm System
This battery replaced an old, failed sealed lead-acid battery in my home alarm's electronics box. The old battery lasted 5.5 years and said on its case "replace every 3 to 5 years". I expect that the new battery will last 10 years or more in standby usage, but only time will tell! The installation was easy with the included adapters that enabled the alarm wires to plug onto the battery's blade terminals. The key thing is that the battery seems to work. The previous low voltage alarm (for the dead lead-acid battery) has stopped and all seems to be working properly. I am happy with my purchase - a theoretical doubling of battery life for a 25% price premium over a lead-acid battery. Good deal.

Great Li Rechargable 12v Battery!
Upgrade your battery-surge protector-back-up units with these Lithium batteries for longer life and much lighter weight! Far more cycling times rated compared to typical sealed types. Just unplug your unit, open the panel or unscrew the cover , unplug the battery-remove old battery-drop in new replacement, re-plug the red/black clips and close cover or screw back together and you have an upgraded and improved surge/battery backup unit! More expensive than conventional batteries but well worth the improvement-Highly Recommended!

Superb product!
Battery ensures home security systems function and report even without AC power. Rapid delivery with Prime. Very, very competitive price. Easy to install. Security system manual says charging the backup battery could take up to 48 hours. This battery took less than 1 hour. Blessed to have made this choice!

Works like a charm
Used it as a replacement battery for a kids ride-on car. Worked like a charm. Holds the charge well. For the price, this battery was a no brainer. Glad i bought it.
