How long does a lithium phosphate battery last?
When the temperature range is from 35°C~40°C for LFP, the calendar life is 5-6 years. But over 45°C, the calendar life will be shortened to 1-2 years. Different cathode materials have varying calendar life properties. For example, lithium iron phosphate (LFP) batteries often have a longer calendar life than nickel-rich chemistries.
How does a lithium battery affect the life of a battery?
The usage of a lithium battery can impact its lifespan. Batteries subjected to heavy or continuous use may degrade faster than those used intermittently or with lighter loads. High current draws or rapid discharge rates can also contribute to degradation. 5. Quality of Battery Management System (BMS)
