Does Keeping A Laptop Plugged In Damage The Battery. Its not the leaving it plugged in that hurts its the total number of time you plug it in to top it off go to 100 that hurts. One of the biggest enemies to battery life is heat so if you are not going to use battery power for a while and keep your laptop plugged in we recommend removing the battery and storing it in a cool place.
But you also need to take care of the excessive heating caused by laptop hardware. A laptop battery will lose its capacity in time no matter what you do. So keeping it plugged in wont harm your battery and cause much difference to the overall battery life.
Explaining it in a different way dont go to 60 or 80 then plug it back in to go to 100 again.
With modern chargers and control electronics it amounts to the exactly the same thing as storing it charged separately from the computer. As Protect Your Gadget points out this does come. But when it comes to prolonging the life of your battery is it bad to keep it plugged in all the time. I personally charge laptops to 80 unless I need the battery life or in the case of my drt I leave it fully charged all the time as I need the power.
