How Long Do Lithium Batteries Last?

The service life of lithium batteries is usually between 2 and 5 years, but the specific life depends on many factors, including battery type, usage, charging method and ambient temperature. Here is some specific information about the life of lithium batteries:

The lifespan of different types of lithium batteries:

Ternary lithium battery: commonly used in electric vehicles and consumer electronics, the cycle life is generally 800-1500 times, the better ones can reach 2000 times, and the service life is about 3-5 years.

Lithium iron phosphate battery: It has a longer cycle life, generally 2000-7000 times. When used in electric vehicles, the life can reach 8-10 years or even longer, and can be used for more than 10 years in energy storage power stations.

Mobile phone lithium battery: Generally, the number of charge and discharge cycles is 500-800 times, and it can be used for about 2-4 years.

Factors affecting the life of lithium batteries:

Charge and discharge depth: Deep charge and discharge will accelerate the battery capacity decay, while shallow charge and discharge will help extend the battery life.

Charging current: Excessive charging current will cause excessive heat to be generated inside the battery, accelerating battery aging.

Operating temperature: High temperature will accelerate battery aging, and low temperature will reduce battery performance.

Ways to extend the life of lithium batteries:

(1) Avoid overcharging and over-discharging, and try to keep the battery power within the range of 20% to 80%.

(2) Use an original or certified charger and avoid using or charging the battery in extreme temperatures.

(3) Fully charge and discharge the battery regularly to maintain its health.\

In short, the service life of lithium batteries is affected by many factors. Through reasonable use and maintenance methods, their service life can be effectively extended.
