What is the average lifespan of a battery?

The average lifespan of a battery can vary depending on several factors. Generally, most batteries last between 2 to 5 years, but this can be influenced by usage patterns, type of battery, and environmental conditions. For example, smartphone batteries tend to degrade after 2 to 3 years of regular use. Laptop batteries, on the other hand, usually last around 3 to 5 years before they start losing their capacity to hold a charge. It is important to note that extreme temperatures, such as extreme heat or cold, can significantly reduce a battery's lifespan. Additionally, factors like battery maintenance, charging habits, and quality of the battery can also impact its longevity. Remember to follow manufacturer guidelines and best practices to maximize your battery's lifespan.
