I’m here to tell you the truth about how to charge your laptop properly

One of the most common misconceptions about charging laptops properly is that leaving the charger plugged into your device all the time will do more damage. 

DO'S AND DON'TS OF CHARGING YOUR PHONE THE RIGHT WAY

This is only partially true. It is perfectly fine to leave your laptop plugged in most of the time and have it charge up to 100%. Most laptops contain either lithium-ion or lithium polymer batteries, and lithium-ion batteries do not have a "memory effect." Therefore, they do not require periodic discharge cycles. 

However, keeping your laptop battery at 100% at all times can ultimately reduce its overall lifespan, as the battery may degrade faster when exposed to high voltage for extended periods. 

To maximize battery life, it's recommended to keep the battery level between 20% and 80% and store the battery at a cool temperature when not in use. Leaving it on the charger sometimes will not kill the battery right away, however, you should just be aware of how long you're leaving it plugged in, and give it a rest now and then.

Absolutely. Buying cheap batteries and power chargers for your laptop will only damage it more quickly. Although it is always nice to save money, think about how much more money you will save in the long run if you spend a little extra on quality batteries and power chargers that won't drain the life of your laptop and force you to buy a new one.

Typically, when you buy a laptop, it will come with a charger that works best with that laptop model. If for some reason, that laptop battery fails or malfunctions, or you lose it, it is best for you to go back to the retailer you bought your laptop from (such as Apple, Best Buy) and see if you can get a replacement.
