As we know that every battery can only sustain a finite number of charge and discharge cycles, after which it starts wearing off quickly.There are two types of batteries i.e Lithium-ion and Lithium-polymer.They have prominently used to power all new laptops worldwide and although they are built using different tech, they function in similar ways.A lithium-based battery cannot be overcharged even if you leave it plugged in at all times because as soon as it is fully charged (100%), the internal circuit prevents further charging until there is a drop in the voltage.

While overcharging isn’t a possibility, keeping your laptop battery discharged is an issue. Keeping your battery in a discharged state for long periods can damage its potential to fully charge again or charge at all.The answer to keeping your laptop plugged in isn’t as straightforward because it depends on a number of factors.Lithium batteries are known for their unstable properties and there are a number of factors like voltage level, temperature and the number of times they have been recharged which contribute to their deteriorating quality over a period of time.High voltage levels while charging can shorten a battery’s life and temperatures over 30° Celsius can severely damage the battery too.

Laptop indispensable lifeline to the majesty that is the Internet. We use them to work and play from anywhere in the world. If you’re like most people, you probably keep yours plugged in when you’re at work or home. You should Stop doing that.Leaving your laptop plugged in will not cause short-term damage, but if you only ever use it on AC power you’ll almost certainly find that after a year the battery’s capacity has been significantly reduced. Also, if you only ever use it on battery power you’ll get through the battery’s discharge cycles quicker.Therefore, the best solution is something of a compromise between the two: use it on battery power some days and keep it plugged in on others. And in all cases, you’ll want to ensure it doesn’t get too hot.In order to squeeze as much life out of your lithium-polymer battery, once your laptop hits 100 percent, unplug it. In fact, you should unplug it before that.
