how long 271 cirl count for macbook pro last

If you are asking about your MacBook Pro battery, start with Get help with your Mac laptop battery - Apple Support.

The battery cycle count is meaningless unless the cycle count is nearing 1,000 cycles.

If the battery is not performing to your expectations, then check the battery condition by Option-clicking on the battery icon on the menu bar. If the battery condition is "Service Recommended", then have Apple or an Apple Authorized Service Provider examine the laptop to provide you a quote for replacing the battery.

Trying to decipher your question, but my first thought is that you're saying you have a 271 battery cycle count and you're asking how many can your Mac take?

Apple's nominal rating for all recent Mac notebook computers is 1000 cycles to an expected 80% battery health. It isn't guaranteed although it's the standard under warranty or AppleCare for battery replacement under warranty. I've seen better performance and worse performance, so your results may vary.

Even under 80% battery health, it could still be reasonably usable - especially if you have access to external power and only need the battery for short periods of use.
