The lifespan of a laptop battery varies depending on several factors, typically ranging from 2 to 5 years. This period is significantly influenced by usage frequency, methods, and environmental conditions. To maximize battery life, it is recommended to charge the battery within a range of 20% to 80% rather than allowing it to fully discharge. Additionally, turning off the power once the battery is fully charged helps extend the battery's lifespan. Each laptop manufacturer offers a feature to set a battery charge limit.
