Don’t Run It Down to Empty
Squeezing every drop of juice out of a lithium ion battery (the type used in today’s laptops) strains and weakens it. Doing this once or twice won’t kill the battery, but the cumulative effect of frequently emptying your battery will shorten its lifespan.
Keep It Cool
Heat breaks down the battery, and reduces its overall life.
When you use your laptop, make sure the vents are unblocked. Never work with the laptop on pillows or cushions. If possible, put it on a raised stand that allows for plenty of airflow.
Give It a Rest
If you’re going to be working exclusively on AC power for a week or more, remove the battery first.
