**How does the number of cycles affect a laptop battery?**

Let me explain in simple terms. Every Li-Ion batteries can charge and discharge only a finite number of times. Let’s say 10,000 times for example. A battery charged from 0% to 100% and discharge from 100% to 0% will include one full cycle. If you charge from say 30% to 80% you have used up 1/4th of a cycle. If the battery discharges to 30% then you have used half a cycle. So every charge-discharge counts.

There is no guaranteed cycle count that a manufacturer can provide. They will give you an approximate. Your battery may last longer if you are lucky and shorter if you are unlucky.

**What happens if my laptop’s battery reached 1,000 battery cycles?**

Usually a good quality battery has 450 to 500 battery cycles, after which the battery capacity drops to 70%. For example, a battery with a capacity of 4400mAh will be 3080mAh after 500 cycles, the output current will also drop depending upon battery quality.

**Pushing it further to 1000 cycles is surely a bad idea as the capacity will drop downto ~1700mAh and cannot output enough current, playing games will forcefully shutdown the laptop. Overcharging may result with the internal leakage of battery cells.**

If you are thinking you are already above 1000 cycles and using the battery, then you are wrong.

You might already know that a charge from 0% to 100% is counted as 1 cycle. But it is not true for all percentage ranges, like charging from 50% to 60% is considered as only 0.02% to 0.03% and from 0% to 1% is ~0.1 cycle.

A daily laptop user might complete 500 cycles in 3 years, and a user how cares that the percentage should not fall below 30% will last for aprox 5 years.
