I purchased these to replace the dead batteries in my CyberPower UPS's purchased from Costco. Computer UPS's usually come with Lead Acid batteries that have a short 3 year life, lower 7Ah capacity, and fast discharge curves. These LiFePO4 batteries work, are much lighter, have longer life, and much higher capacities. I improve my UPS's capacity by 40% and don't have to worry about these batteries dying.

2nd Update: After receiving a replacement battery and testing it, it passed with exceptional performance. After fully charging it, I placed a 1.0 amp load on it for 5.0 hours. After resting, it settled at 13.1v, which is 60%-70% SOC. Awesome. Update: While I stand by my original evaluation of the battery, the seller engaged me in an honest technical discussion of my testing process via several conversations. I'm open to admitting my mistakes in exchange for learning. I think they were honestly interested in resolving any issues with their product or my review. Initial review: Fully charged the battery. Applied a 1.0amp load. After 5.0 hrs, the battery, after sitting unloaded for 30 minutes, measured 12.60vdc. At best, this is a 30% SOC. This is barely an 8ah battery, not a 10ah battery.

Your battery has performed flawlessly on a rechargeable setup for game cameras. It has been a set it and forget it setup. Great quality at a great price!

Why did you pick this product vs others?: Great size and weight for portable amateur radio operation. Battery power: Lasts all day…

Great little lightweight batteries for anything that needs a back up power supply.
