## Description

12V 20Ah Lithium Battery LiFePO4

Review: Effective replacement battery for computer UPS. - 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.
Review: Works great with my solar-powered chicken coop controller - I installed this 12.8V 20Ah LiFePO4 battery to replace the 12V 18Ah lead-acid battery that came with my solar-powered chicken coop controller. The original lasted about 8 years, so it'll be interesting to see how long this one holds up. So far, it's been a great upgrade. It fits perfectly, weighs significantly less, and I really like the built-in carrying handle. My coop controller shows it's running at 13.3V, which, according to the battery's manual, means it's charged to around 70–90%. The manual is actually very informative, which I appreciate. Some quick specs worth noting: Battery type: LiFePO4, 12.8V, 20Ah Unit I recieved was 6.1" tall Terminal type: M5 Max continuous discharge current: 20A Peak discharge (5 seconds): 40A Max load power: 256W Operating temperature range: 41°F to 113°F (should be interesting to see how it performs in our cold winters) Charging voltage: 14.3V (±0.2V) Recommended charging current: 4A Note: This battery doesn't provide cold cranking amps (CCA), so it’s not suitable for starting motorcycles or vehicles. Overall, I'm happy with the upgrade. If it holds up through the winter and over time, I’ll consider switching other 12V lead-acid systems over to LiFePO4 as well.

### ⭐⭐⭐⭐⭐ Very good value
*by R***N on February 24, 2026*

This battery arrived on time and seems solidly built. I am using the battery to power a Garmin fishfinder. I was very pleased that after I installed the battery my Garmin showed that it was receiving 13.6 watts. This should provide optimal picture quality on that unit. I feel like I received great a very good battery at an optimal price.
