A notebook battery in good shape will last longer, so always take care of your notebook’s battery.
Not sure how to do that? Here’s how:

• Handle your battery with care. Be careful not to drop the battery or hit it against hard objects.
• Keep your notebook battery away from extreme heat.
• Clean your battery contacts regularly with a cloth moistened with rubbing alcohol.
• If you have a Windows PC, use Hibernate mode instead of Sleep mode when not using your computer for an extended period of time.
