assuming a reasonably modern (last 5 years?) laptop with a lithium-ion
battery, your battery's useful life is the shorter of
~400 full discharge/recharge cycles (+/- 200)
3-5 years from date of manufacture
after that, the battery charge will last about half as long as when it
was new, and it will continue to deteriorate.
