How Many Cycles Does a MacBook Battery Last

No, as that would be a step back, wouldn't it, if older batteries could be used less plugged in, than newer ones? Just make sure you calibrate once a month.

Laptop Battery Guide
I thought leaving the Macbook Pro's plugged in had no effect on your life cycle. Isnt there a feature in the New Macbook Pro batteries, that detects if your plugged in, and uses the power adapter for power, rather then the battery.
just out of curiosity, does Apple have a rule for replacements on batteries? eg. if i got thru 30 cycles and my battery is down to 70% within a year?
take my advice. Pull the swollen battery ASAP. You can run the macbook pro without it (although your processor speed will be slower). You dont want to let it swell more... at the very least it's going to heat things up, at worst it'll damage the macbook pro internals, including trackpad, logic board, etc. Dont wait, you have been lucky so far...
(my replacement battery, age 18 months, R.I.P )
PS . Just to clarify, this picture shows how mine continued to swell after I removed it. I assumed removing it would stop the expansion, but it continued to 'grow'. I snapped the picture as I was about to return it to a genius bar (your best bet -- don't try to handle the replacement online, you may get less satisfactory results). You do not want this (or worse) to happen while it's still in your computer.

How Many Cycles Does a MacBook Battery Last
I use my macbook on a daily basis and charge every other day in most instances. I never shutdown my system...almost never. I close the lid to put it to sleep and then take it with me to the office. I pop it open at lunch for an hour or so (screen fairly bright) and then use it at home in the evening...sometimes in clamshell mode, most times just on my lap.
I've gotten a lot of life out of the battery and appears it's going to continue based on the cycles and health.

Last time I checked my late-2007 macbook battery was at about 1200 cycles and still 80% capacity.
However, I neglected to charge it for about a month and deep-discharged it, rendering it useless. It was still running a 5 or so hour capacity before that though.

Ok so how frequent you use your battery or most of the time you just plugged in?
Well according to coconut battery ive used my computer for 37 months:
and ive used my computer on most days for at least 6 hrs a day. I goto school and charge it about once in the school day. And then when i get home i usually use it until it turns red and then plug in the charger and then leave it until the morning where unplug the computer and repeat the process. but most of the time at home i use my computer on charge mode.
ofc somewhere in my first year of use the time ive had this computer suddenly reset..

This is my battery. New MacBook Pro, but the battery is varying from 90-100%, which is normal.
What application is that?
I've owned my Mac since last Wednesday, and I've put 5 cycles on it so far, somehow. It's only actually run flat once so I'm not quite sure how that happened.
Either way, what is a "usual" amount of cycles in a month for best life? I know that's a bit of a weird question but whatever
