The battery life of a lithium-ion battery depends on several factors, including its chemistry, usage patterns, and operating conditions. Generally, a lithium-ion battery can last for hundreds of charge-discharge cycles before its capacity begins to degrade. The number of cycles a battery can endure before its capacity starts to decline depends on many factors such as the quality of the battery, the depth of discharge, and the temperature during charge and discharge.
Lithium-ion batteries typically retain around 80% of their original capacity after 300-500 charge-discharge cycles. However, this can vary depending on the specific battery chemistry, how the battery is used, and the conditions it is exposed to. High temperatures can accelerate the degradation of lithium-ion batteries, so it’s important to avoid exposing them to high temperatures.
Battery manufacturers typically rate their lithium-ion batteries based on their expected lifespan, which is typically given in terms of the number of charge-discharge cycles or the number of years the battery is expected to last. For example, some laptop batteries are rated for 300-500 charge-discharge cycles, while others are rated for up to 1000 cycles or more. Electric vehicle batteries are typically rated for 150,000 to 300,000 miles before their capacity degrades to 80% of their original capacity.
