LiFePO4 lithium batteries, also known as lithium-iron-phosphate batteries, are known for their longevity. They typically offer at least 3000 full charge cycles before they begin to lose capacity. Better quality lithium iron LiFePO4 battery running under ideal conditions can exceed 10,000 cycles. If you charge and discharge the battery once per day, it can last for about 13 to 19 years. However, with proper care, a LiFePO4 lithium battery can last up to 10 years or more. Please note that the exact lifespan of these lifepo4 lithium batteries can vary based on several factors including the type of usage.

How Long will a 100Ah LiFePO4 Battery Last?

In terms of runtime, a 12V 100Ah LiFePO4 battery can last anywhere from 5 days to half an hour, depending on the load you run on it. For example, a 12 volt LiFePO4 battery 100Ah will last about 2 hours while running a 500 watt AC load.

Please note that these are general estimates and the exact lifespan and runtime can vary based on several factors including the type of usage. It’s always recommended to follow the manufacturer’s guidelines for charging and discharging to ensure the long-term health and safety of the LiFePO4 lithium battery.
