I bought two of these to power a remote astronomy setup at 10,500 feet elevation. They work great in the cold, and provide steady power all night for a variety of equipment. I trade off using one and charging the other on a solar panel. Very reliable, lightweight, and reasonably priced!
Works great

This Battery replaces a golf cart 12v 20 a-hr lead acid battery, and another similar battery that was powering an electric wheel barrow. Both devices work better than before.
Great product

Great product. I was ordering a small quantity and it's nice to find a store that has no minimum order size..
