So they tell you that.

Most of the charger manufacture will say "plug in, no problem". However, 99% of all laptop batteries in our company dead because of the constant plug in. Think about this, though the charger is designed to not charge when battery is full, what about just losing some 1% of charge? The charger will charge that 1% up, over and over again. If the laptop was used for short meetings daily, the charged portion is just that much.

Though the battery manufactures will claim no memory effect, they do have!

The safest way is to discharge a battery almost totally, then charge it. This way you can get the most out of that battery. When plug in power, take the battery out!

Of course not everyone can do that, and that is why battery manufactures can make lots of money and pollute earth over and over.
