How Long Do Batteries Last?

Curious about how long do batteries last? Let’s discuss here.

Still find the answer how long do batteries last? Laptop battery run-time is difficult to determine. Actually laptop battery run-time depending on the power demands made by the laptop components. monitor, hard drive and other accessories results in an extra drain on the battery, effectively reducing its run-time.

To study its runtime of battery or Watt-Hours, Volts and Amps multiplied by each other. Generally, the higher the longer volt Watt-Hour, but it still varies depending on the Amps. To locate your battery runtime, consider the formula below.

11.1 Volt, 6600 mAh (6.6 Ampere)

11.1 x 6.6 = 73.26 Watt-Hours

The 11.1 volt 6600 mAh battery can power a laptop around 73.26 watts for one hour. Now to estimate how long the battery will last in your laptop requires a different configuration to divide 73.26 Watt-Hours by the wattage of your laptop.
