Clamshell mode safe for the battery?

I've been reading a lot on clamshell mode but Im still debating whether is should do it or not. I am a programmer so Im using my computer 24/7. How bad is clamshell mode for the battery. I read that you need to use the battery at least once a month. Apparently it doesn't damage the battery at all. Would it be fine if once I'm done using it, I disconnect the AC adapter?

Hi,


There are vastly differing opinions on this. If you run on power adapter as much as possible, then you're saving "cycles" of which your battery has limited amount of. Age will also take its toll on a battery, no matter the usage. Some people will recommend running the battery down about 75% at once a month to keep it "exercised" which Lithium Ion batteries do need, but Apple has built that in to their charging circuit; after charging to 100% the battery won't charge anymore until it runs down to about 95% (which will occur naturally over time even with it plugged in), then charge it back up to 100%, etc.


Apple doesn’t say there’s anything wrong with leaving your Mac notebook plugged in, nor do they say you need to discharge it ever (unless you’re not going to use your Mac portable long term) so they don’t think it’s a problem either: http://www.apple.com/batteries/maximizing-performance/


I wouldn't worry about it at all. I sometimes go months without running on battery power with one of my MBPs and don't even think about worrying about it.
