Getting the Most From Your Laptop Battery

The laptop battery is the source of power for your laptop, enabling you to take it with you when you are on the go. It is a complex unit, and its lifespan is dependent upon many factors that can affect how long your laptop will operate when unplugged from a power source. The good news is that, with proper care, your laptop battery can last much longer than you might think.

There are a number of different types of batteries that can be used in laptops. Two older types that were once very popular, nickel cadmium (NiCad) and nickel metal hydride (NiMH), are now very rarely seen in new laptops. This is because these batteries suffered from The Dreaded Memory Effect, a condition whereby they remember that they are already charged and do not fully discharge during use. This will eventually reduce the battery’s ability to hold a charge, and can even render it useless.

Most modern laptops come with Lithium Ion (LiON) batteries. These are much lighter and have a longer runtime than the older NiCad and NiMH batteries. LiON batteries are also more energy efficient than their predecessors, but they are not indestructible and can be damaged.

If you want to get the most from your laptop battery, follow some simple rules. Always keep it cool and do not overcharge it. It is also best not to leave the battery plugged in when it is not in use. A quick charge when needed is fine, but you should allow it to reach a full charge before disconnecting. This prevents a condition known as shallow cycling. Shallow cycling occurs when you regularly recharge your battery without letting it reach its full charge.

The amount of heat your battery has to dissipate is another important factor. Laptops tend to generate a lot of heat, especially when running demanding applications or games. This can make the battery overheat, and the internal circuits can start to short out. Using a laptop cooler can help to dissipate the heat more effectively, keeping your battery cool and lasting longer.

Finally, be sure to remove the battery when possible and store it in a cool place. Avoid putting it in the refrigerator, where condensation can occur. It is a good idea to store it in a plastic bag with a label containing the battery model, part number and manufacturer name.

Using a surge protector, practicing the above tips and following the operating system tweaks and customizations provided by your computer’s manufacturers can all help you to extend the life of your laptop battery. With a little bit of effort, you can enjoy a day away from the charger without worrying about when your laptop will run out of juice. Good luck!
