keeping plugged in all the time? charging

[kayleee]

I know i created another thread like this but this is different, is it good for battery if I just keep the charger on and plugged in ALL the time...?

i know its smart enough to stop charging when it reaches 100% , but it will be at 100% almost all the time....is that possible?

thank you

It won't hurt a thing to do that. Like you mentioned, once it is fully charged it will stop charging until the battery level drifts down again.

You're correct that it won't try to overcharge, but keeping the battery fully charged does induce stress on it. Apple recommends unplugging the MacBook at least once per month and discharging it partially.

Apple says nothing about that on their battery info pages. It now't hurt the battery at all to leave it fully charged when plugged in.
