Battery cycle count

Um, how do you guys check the battery health %? Mine only shows 20 cycle count and battery health: Good. I don't know how to check the %. Any advise is highly appreciated.
Huh?
What does this all mean?
Mine is at:
91% HEALTH
53 CYCLE
78% CHARGE
Does this mean when my battery's health goes to 0, my MacBook Air is a bust??? Does this mean that once the battery's health is all gone, I have to get a new notebook? Please elaborate further on this whole thing. Thanks.

wow you guys are light users compared to me. 139 cycles 95% health. I bought it early March this year. Bought it everyday with me in university and I take notes with it.
And there was I worrying that I was a heavy user with 41 cycles on my MacBook Air since the end of March (94% health)!
My MacBook Pro on the other hand has only 53 cycles (and 100% Health) in 14 months. However, it is plugged in most of the time.
Anyone over 200 cycles yet?
Some of you are climbing in cycle counts pretty quickly. I have slowed down due to work requirements and not yet near 200. I am anxious to see how this built in battery will last under sustained use.
My charge times are still much slower than I would like, but I find it irritating to have to carry any computer but the MBA now. The screen and size factor just can't be beat.

No, you don't have to buy a new macbook when you batter health goes down. Actually if you are under 300 cycles and your battery went below 80% health, apple will gladly replace the battery for you. However if you are over 300 cycles before you battery becomes wonky then you would have to purchase the battery yourself. The battery is usually around $150 dollars if I'm not mistaken.
Update on mine:
Bought mine mid-March of '08. Now with 203 cycles and 99% health. My battery's health seems to have increased a bit...go figure

I am at 206 Cycles! Battery Health at 91%
This is the first time I've checked.
So far so good. No problems with my MacBook Air except the Audio cable became damaged and apple took it's dear sweet time fixing....over a week and I am a pro care member!

keep in mind that batteries deteriorate whether you use them or not
.... starting from the date of manufacture. Heavy cycling only accelerates the process, but generally if it's not too heavy it won't influence a battery's life, which is 2-3 years from the date of manufacture.
So better not to focus on the cycles.
As usual, dansdata.com is the best source of information on this.

Remember, for any Apple product, the 2 main enemies of battery health are HEAT and draining the batts completely.
Thus, you always want some ventilation beneath the unit, and never leave it to cook in direct sunlight or in a hot car.
Draining the battery to a very low % will shorten its life as well. For best results, shut off your device before reaching, say, 10-20% battery life.
