How long does the battery last on average?

On average, laptop batteries generally last between two to four years, depending on several factors. The actual lifespan can vary due to the battery's chemistry, usage patterns, and maintenance practices. Typically, lithium-ion batteries, which are commonly used in laptops, have a limited number of charge cycles before their capacity starts to degrade. A charge cycle involves discharging the battery completely and then fully recharging it. For moderate usage, which includes regular browsing and office tasks, a laptop battery can retain around 80% of its original capacity after 300-500 charge cycles. However, heavy usage, such as gaming or running resource-intensive software, can cause the battery's capacity to deteriorate faster. Regularly calibrating the battery, avoiding extreme temperatures, and not overcharging or fully discharging it can help extend the lifespan.
