12V 10Ah LiFePO4 Battery, 5000+ Deep Cycles & 10-Year Lifetime, Lightweight Lithium Battery with 10A BMS, Ideal for Fish Finders, Power Wheels, UPS, Ride-on Toy, Kayak, Solar and SLA Replacement

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.

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.

Item with great quality. Arrived on time. Power and amperage as supposed to be.

These are great for a battery back up system. I have used them in two different APC units and they are working great. They are also lighter than the SLA batteries, so that is a plus.

Short, Sweet, Simple and to the point review. This is a straightforward, reliable battery perfect for my outdoor trail camera setup. It’s been working flawlessly with no issues related to charge or power output. The materials feel solid, and the metal prongs are sturdy, suggesting they’ll last for a long time. Just remember to fully charge it once you receive it, as it doesn't come pre-charged. After a month of use on a single charge, with several pictures taken and sent to my phone, the power level is still nearly full. I’m very happy with this purchase, as it eliminates the need to constantly replace 16 AA batteries.
