i dont think theres a need to take out the battery,the macbook bypasses the battery when it uses AC.

are you sure? I noticed that whenever i'm on AC my battery is charging....can anyone confirm this pls. Thanks

bro, are u sure? check ur magsafe indicator light..
green - nop, no charging
red - yes, charging

you can see teh battery indicator on the top panel,if its a lightning symbol means its charging if its a power cord symbol its using AC

if it is fully charge then its green....

it's always advisable & in good care to take out your battery if you're using your laptop while it's plugged-in to a power source for a long period of time. from my own experience, there'll be a deterioration of your battery's health, which i observed using CoconutBattery, back when i was being careless with my macbook pro. initially with a 100% charge, it'll last about 4 - 4.5 hours. now it's more like 3 hours.

so don't be lazy guys do what's best for your mac.

my mbp only abt 3 hours .... not the promised 5

Come on, how many times does anyone has to repeat this, DONT TAKE OUT THE BATTERY, it does no good to your battery, it does no good to your Mac. Period. Anyone wants to question this, search and learn. Just leave the battery in, your Mac does not use the battery when connected to AC, and it is safer this way also, just imagine losing power and not having battery in the middle of processing something, ESPECIALLY when scanning your drive etc.

Basic battery care:-

1. Use it till empty before charging, not use charge use charge as you like;
2. Charge it till full whenever charging;
3. Leave it in when on AC, just use it up once a while (once a month or so);
4. When storing away your battery (not in use for long time), leave it at 40% charge, not full, not empty.

Anyone still not convinced, look at my battery health posted in this thread, 1st page.

Not promised, but it was rated, and depends very much on the use. Wifi, bluetooth etc.

Shouldn't remove the battery pack from MacBook/MacBook Pro when your using it because the charger doesn't charge the battery pack once it's full (green, 100%). Also, removing the battery pack and using it directly from the charger will cause your MacBook/MacBook Pro to run in lower performance mode due to the lack of power. You see, the MacBook/MacBook Pro draws power that can't be supplied through the charger itself so it requires help from the battery pack. Hope I've helped.

im using wifi only, bluetooth is switch off

I use @ lowest brightness, Wi-Fi on, Bluetooth off @ MacBook (plastic, white) can get 4 hours easily but on continuous surfing with no flash webpages/resource intensive webpages.

er... my brighness is at 2-3 petak only

My brightness is only filled up by 1 box.

now i also fill up one box nia, test and see how
only advantage of my vaio is the 5 hour usage

Some "netbooks" got more than 6 hours.

yea, i heard my fren eeepc does tat, but for tat puny reso screen, n pariah processor, i dun think y not

anyone knows what happen to my battery icon on the top right where u can't choose the battery selection from better performance to better battery life option??

i do calibration once a week or sometimes once 2weeks depend on my usage.
my macbook black is 9months old and 23 cycles, battery life still in good condition.
also, dont take out the battery when u using it and on power cause it will reduce the performances.
sometimes my macbook show i got 8hrs if usage when i turn on but when u start using it...it gets to 4-5hrs.....
so pls do calibration once a while to let the battery "juice" flow...
