Batter and better the Battery

They always say that you need to calibrate your laptop battery and that it only needs doing once. This just seems to involve running it right down and then charging it up again. Those in the know about these things say it helps prolong the battery life so by jingo, if it's good enough for them then it's certainly good enough for me.

Even as I type this, I am running it down to less than 15%.

You have to fully charge and then discharge your battery only once to calibrate it. After that, you can connect and disconnect the power adapter when the battery is at any charge level.
