These days it’s not uncommon for laptops to serve desktop duty. But here’s the rub: If you leave the battery inside the system 24/7, it’ll keep drawing power, even when fully charged. That’s not only a waste of energy and money, but also bad news for the battery: Constant charging will reduce its capacity to hold a charge and its overall longevity.
Fortunately, there’s a fast and simple solution: Pull the battery out. Most notebooks can run off AC power when there’s no battery present, so take the latter out of the equation. It’ll stay in pristine condition and save you a kilowatt or two. Estimated savings: A few dollars on your monthly electric bill and $120 on premature battery replacement.
