These days there\u2019s a lot of talk about mobile phone batteries and how to charge them, but laptop batteries are in a category of their own and deserve a closer look. Your laptop battery is one of its most important components \u2013 even though we tend to focus more on things like screen size or RAM and processor power when we talk about laptops. Laptop batteries need particular care and attention, and a lack of this is why many laptop owners end up having to replace their batteries sooner than they\u2019d like. Here are some tips and tricks for charging your laptop battery so you can get the most out of its lifespan.<\/p>\n

Charging your laptop<\/h2>\n

Should I leave my laptop plugged in all the time?<\/h3>\n

This is a very common question among laptop owners. The answer is straightforward: \u201cNo\u201d. For best battery performance and maximum lifespan for your laptop battery, keeping the charge between 40% and 80% is considered ideal. However, new\u2011generation lithium batteries perform better with full charge cycles, so it\u2019s best not to let the charge drop below 40%. There is also another key reason not to leave the battery charging constantly: on many laptop models, once the battery reaches 100%, power to the battery is cut, so there is no point in keeping it on charge from that moment and in most cases it will not be damaged.<\/p>\n

Should I completely drain my battery before charging it again?<\/h3>\n

This is another frequent question about charging laptop batteries. The answer (as you can probably guess from the previous question) is no. Most modern laptop batteries are lithium\u2011ion or lithium\u2011polymer and are designed to handle many charge cycles. As mentioned above, leaving your laptop permanently plugged in is not necessarily harmful to your battery, although laptop batteries do have a limited number of charge\u2013discharge cycles.<\/p>\n

What are the best tips for charging a laptop battery?<\/h4>\n

Not all laptops have removable batteries for cooling. In addition, internal cooling fans can fail after a few years. Here are some tips for laptop owners that should help you maximise your laptop battery life:<\/p>\n

    \n
  • Avoid fully discharging your laptop after you\u2019ve recharged it. The best approach is to keep the battery level between 40% and 80%.<\/li>\n
  • Make sure your laptop doesn\u2019t get too hot and that the cooling fan is working properly.<\/li>\n<\/ul>\n

    Your laptop battery cannot overcharge and become damaged by excessive charging. It is smart enough to bypass incoming charge once full.<\/p>\n

    Batteries charged to 100% usually provide only 300 to 500 discharge cycles. Those kept at around 80% can benefit from almost four times as many recharge cycles.<\/p>\n

    IT technicians also offer a few useful tips on charging laptop batteries, including preserving battery life by disabling unused devices and ports, and selecting battery saver or eco mode, which will put your laptop into low\u2011power states and reduce battery drain.<\/p>\n","protected":false},"excerpt":{"rendered":"
