How long does mAh battery last?

You can learn about Amp Hour or Ampere Hour. For instance, a 3000 mAh battery could power a device drawing 100 mA (milliamp) for 30 hours. A device drawing 200 mA would last only 15 hours.

Is it better to have a higher mAh?

Batteries with larger mAh ratings generally last longer than those with smaller ratings, assuming that the batteries are subjected to the same patterns of usage, but it may not mean a better battery. The milliampere hour represents a unit of electrical charge commonly used to measure battery capacity.

Does mAh matter when replacing a battery?

The answer is yes, mAh only refers to power capacity and how many milliamps the laptop battery can deliver per hour. The more important compatibility measurement is the voltage it supplies. … The basic idea is that 5800 mAh battery pack will allow your laptop to run longer than a battery with a 4400 mAh rating.

How much mAh battery is best?

How many hours does a 3300 mAh battery last?

Convert mAh (milliamphours) to time in hours The formula is (mAh)/(Amps*1000) = (hours). For example, if you have a 3000 mAh battery that runs at 0.2 Amps (0.2Amps = 200mA), then the time that the battery will last for is (3000)/(0.2*1000) = (3000)/(200)= 15 Hours.
