MacBook battery while plugged in?

[Buskape]

I have a question about the unibody macbook battery,

when it is plugged in, and fully charge (icon says "Recharged") does the power automatically come directly from the adapter or still from the battery?

Does the battery unloads itself to 99% then charges back to 100% all the time? or is there some smart system that prevents that?

I guess if it didn't it after 100 recharges of going from 99 to 100% it would count as a cycle??

Thanks for enlighting me up!

I don't know exactly what happens, but I know that the battery DOES NOT drop charge while plugged in, and I have noticed that it will not start recharging until it gets down to under 94%. Like for instance, if you unplug your laptop for a few minutes, when you go plug it back, it won't start charging if it's over 95%.

Your Mac uses your adapter. However, when your Mac requires more power than what your AC can provide (eg when you put 100% processing power due to video encoding) then your Mac uses both your AC and battery.

That is why Apple recommends not to take off your Mac's battery.

I never knew that. Learn something new everyday. I just heard not to take the battery out, now I know why, thanks.

Since someone is talking about battery I do have a battery related question. I just got the unibody MacBook and have been using it for the last few days. One thing I noticed and wondered whether this is something normal with these macbooks or it's just mine. I think it takes long time to fully charge the battery. I would think two hours should be more than enough to fully charge the battery, but it's still charging as I am typing this post. Is it perhaps because the battery is Li Polymer? Like I said this is my very first Mac and I don't know whether this is the norm or something is wrong with my macbook. Other than that I'm having a very fun and interesting time just poking around trying to acclimate myself to OS X.

It's normal. Using your Mac it takes a while to charge up. As it gets closer to 100% it will take even more. Think of filling a glass of water. At first you start fast, then slow down to drops.

However, if your Mac is asleep or off, battery chargers way faster.

Thank you for your info. And you are right about it taking even longer as it nears completion; it's like watching water drip, drip, drip as if it's just trying to top off just at the brim.
