Laptop batteries don’t last forever. And there are a few things you can do to ensure a more extended, healthier battery. Turn your laptop over and gently blow on your back for 10-15 minutes daily to keep it cool. Most people overlook these.
Excessive heat isn’t just bad for your processor (and your wrap) and your battery. A hot battery degrades much faster than a cold battery. While it’s best to keep your laptop away from the heat when using it, it’s equally essential when storing it.
If the laptop is stored at temperatures between 32 and 55 degrees and used daily, the battery will only deplete 4% of its total charge after three months. Conversely, if the laptop is used daily in temperatures of 80-100 degrees, the battery will lose 20-30% of its total charge.
Don’t leave your battery fully charged.
Ever heard of the 40/80 rule? The charge should be between 40% and 80% for nickel-based batteries. After setting it to 100%, do not leave it plugged in. This is what most of us do, but it’s another thing that affects the health of your battery.
Lithium-ion batteries work best if they are slightly discharged and then charged somewhat, rather than constantly discharging to 0%. Research shows that discharging to 50% is better for long battery life than discharging to 90% lightly or hard discharging to 0% (50% discharge provides the optimum number of cycles). Lithium-ion batteries shouldn’t be drained regularly, but most modern batteries are “smart batteries.”
