How long does a lithium battery last?

The storage capacity of lithium (LFP) battery systems is typically measured in kWh (Kilowatt hours), while the most common metric used to determine battery lifespan is the number of charge cycles until a certain amount of energy is lost. This generally ranges from 3000 to 5000 cycles over a battery life of 10 to 15 years.

How do you prolong the life of a lithium battery?

Instead, use partial cycles (20%-80%) to prolong battery life. Proper care and maintenance can significantly extend the lithium battery lifespan, saving costs and enhancing reliability. Here are five proven strategies to maximize the lithium battery life expectancy.

How long can a lithium battery hold a charge?

Lithium batteries can hold a charge for several months when not in use, thanks to their low self-discharge rate of around 2-3% per month. This makes them ideal for applications like backup power systems and seasonal equipment. However, factors like storage temperature and battery health may affect performance. 4.

How long does a battery last?

This generally ranges from 3000 to 5000 cycles over a battery life of 10 to 15 years. A lesser-known metric of lifespan, often only specified in the warranty document, is the energy throughput per year in MWh (megawatt hours). There is some debate about which metric is the most critical, which we examine later in this article.

What factors affect the lifespan of a lithium battery?

Environmental and Charging Conditions Environmental factors such as temperature and charging habits also influence the lifespan of lithium batteries. High temperatures (>35°C or 95°F) and frequent fast charging can accelerate degradation, reducing the total number of usable cycles.

What is battery cycle life?

Cycle life measures the number of charge-discharge cycles a battery can undergo before its capacity drops below 80%. It’s a critical factor in the lithium battery lifespan. What is Cycle Life? A cycle begins when a battery is fully charged and discharged. Partial cycles, such as charging from 50% to 80%, count as part of a full cycle.
