Not sure how many but my mbp is 13 months old with 17 cycles. It's running at 98% capacity

Apple has a great site for how to maintain and use your batteries properly for all of their devices:
Apple - Batteries
In addition, you'll find a lot of great information by searching here at Mac-Forums. There are many threads out there that you'll find useful on this subject:

Not sure which 15" MacBook Pro you have (you didn't say)...but if it's an older MBP 15" with the user replaceable battery...you're supposed to get around 300 charge/discharge cycles...if it's a newer 15" MBP with the "non-user replaceable battery"...you're supposed to get 1000.
But...remember...your "mileage" may & will vary depending on how the battery is maintained (see link earlier in this thread).
HTH,

p.s. Yes...I'm sure there are folks that have gotten more/less than the numbers mentioned above. The numbers are mostly for reference.

My new Macbook Pro finally arrived today after some issues with TNT international courier, but never the less... I had absolutely no idea these new batteries are meant to have a 1000 cycle count. That's great.

Just in case anyone wanted to actually see it in writing (regarding 1000 charge/discharge cycles with the newer batteries)...here it is:
Apple - Batteries - Notebooks
...it actually says up to 1000 "full capacity" charge/discharge cycles. So if you factor in the number of charge/discharge cycles you will get at less than full capacity...that would or should be well over 1000 cycles.

sorry to raise this but since we're in the issue regarding battery cycle... what is the optimum charging cycle do you guys do? I usually charge my battery when i hit 5% battery charge left and charge it to 100%. Once full, I take out my adapter.
I read this Apple - Batteries already but it didn't mention anything about this.

You should be alright, anytime it turns red you can charge it.

- Back to my old 2.2GHz C2D MB after selling my MBP and wondering what my next Mac will be :)

Aluminium unibody Macbook here, the short lived one with the removable battery.
2 years old, original battery. It's on 604 cycles with 98% of the original capacity available. Gets 4 hours from a charge easily.
It's a huge contrast to my previous original type Core Duo MacBook Pro. That munched it's way through three batteries in three years. One failed early under the recall, the other two had little over 10-15 minutes life in the battery after 250 cycles.
This is a good'un and I'm keeping it!
