your ability to write in English is better than my ability to write in your language! As long as you don’t get a “replace battery” warning, you can keep using it for as long as you’re content with its gradually decreasing health.MacBook Pro, OS X Mavericks (10.9.1)

cycle counts, contrary to popular myth, dont mean much
Counting charge cycles means next to nothing
Cycle counting doesnt amount to much at all except in LONG TERM.
I can, on purpose if so inclined, kill a battery in 100 cycles or less due to mistreatment
People with 100 or fewer cycles after 3 years have their Macbooks always plugged in and on charge which isnt a good thing at all.
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.
As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
(as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
Amount of deep DOD (depth of discharges) matters, not charge cycles except in long term ideal treatment of a battery
meaning as per Lithium batteries 'riding' a battery harshly into the ground every 'mile' accounts for far far more wear than gently 'riding' a lithium battery many many miles.
