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.

Half the weight of AGM
Half the weight of the AGM it replaced. Time will tell if it holds up. Fit and finish were correct

Doesn't last
Lithium batteries are the way to go. They are light and maintain their voltage until almost completely discharged. Best of all is that the prices have fallen to match that of regular lead acid gel batteries. As such I purchased 6 of these batteries to power my GPS system and a model boat. Within just a couple of uses three of them no longer work. I expect the remaining ones to fail as well. As much as I hate writing a negative review I'd like to share my experience with these batteries. I have ordered 4 more from a different company and hope they will last longer.

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!

Great upgrade for my son's electric dirtbike
I was skeptical at first, because they were very lightweight. I installed them into my son's electric dirtbike that would barely run for 30 seconds before running out of juice. Now he rides it for a very long time in the evenings, and he still hasn't run them empty yet! Very pleased with this purchase.

Battery doesn't hold a charge
The battery will not hold a charge over about a week! After complaining to the vendor, the company gave me a complete refund. I then bought the same battery and it has worked well. I am happy with the second purchase
