The best things you can do to improve battery life. A laptop battery is not going to last longer but there are some things you can do to ensure a longer, healthier battery. Just "keep it cool" excess heat is not only bad for your processor, but your battery as well. "Don't leave it fully charge"applies more towards nickel-based batteries saying that you should keep the charge between 40% and 80%. "Perform shallow discharges" discharges to 50% are better for your battery's long-term life span. "Fully discharge once a month" batteries shouldn't be discharged regularly.
