Same as the title, am I supposed to take my battery out when I leave my computer plugged in for extended periods of time. Currently I don't take my computer off my desk much and don't want to ruin my battery life as I only take it on the go once every few months (but when I do need it on the go, I need it a lot). Any advice?

I don't on my MacBook. If you take the battery out two things could happen.

1. The battery will slowly drain with no power to it.

2. You could get crap inside the battery bay that would not otherwise get in there if the battery was there. This includes dust which will get in there no matter how clean of a surface you try to keep in on.

Hope this helps.
 
Where did you see that advice about taking the battery out when plugged in for extended periods of time?

Sure you don't mean when computer is stored for long periods of time and not plugged in?

i keep my macbook plugged in most of the time and only remove it a couple of times a week
doesn't seem to be hurting it at all
i was told that the macbook stops charging when it is full to stop over-charging
someone with more knowledge on this may be able to confirm? cheers
 
No, I would not recommend it.

1. Previous Apple machines run slower when the battery is removed (no one has ran any tests on the current machines).

2. If you accidentally knock off the Magsafe connector you'll loose any unsaved data and you may corrupt files.

3. The battery is not constantly charged up. Once the battery hits full charge the charging stops. If the battery looses charge over time it won't start recharging until it hits something around 95% give or take a couple percentage points.

thanks that's what i was talking abt :D
 
I have a different opinion.

Even though new Batteries do not have the memory effect, it is still advisable to charge it all the way, and then use it all the way to the end.

If you are using your computer on the desk with powercable , you should take out the battery because as mentioned earlier the battery is constantly between 95% and 100% which ultimately reduces the capacity.
 
Also it is good to cycle(complete charge, then drain to no power) your battery on occasion. I do it at least once a week.
 
as mentioned earlier i would personally not take out the battery.

I would just leave it plugged in...even better i'd take the ac adapter off at least once in a while to give the battery a good work out.

With the battery out, the chances of you knocking out the magsafe adapter are just too high and risky.
