Lithium batteries, especially LiFePO4 (lithium iron phosphate), can last up to 10 years under optimal conditions. Factors like charge cycles, temperature, and usage patterns influence longevity. While standard lithium-ion batteries degrade faster (2-3 years), LiFePO4’s… Do Lithium Batteries Really Last 10 Years? Exploring the Longevity of LiFePO4 Batteries
