Understanding Laptop Battery Lifespan

Your laptop battery, like all batteries, has a limited lifespan. Understanding this lifespan is crucial in knowing when it’s time to replace your laptop battery.

  • Battery Cycle Count: This refers to the number of complete charge and discharge cycles a battery can undergo before its capacity significantly decreases. Most laptop batteries last around 300-500 cycles.
  • Degradation Over Time: As time passes, your battery’s capacity decreases. For instance, after 1-2 years, you might notice that your battery doesn’t hold a charge as it used to.
  • Temperature Impact: High temperatures can accelerate battery degradation. Avoid exposing your laptop to extreme heat to prolong your battery’s life.
  • Usage Patterns: How you use your laptop affects its battery lifespan. Heavy usage and running power-intensive applications can strain the battery.
