It will last just 1 hour if you draw 4000 mA of current from it..

## How long does a 2200 mAh battery last?

It depends on the load or current draw. The “MAH” is an acronym for “milli amp hour”, which is sort of cryptically self explanatory. With a steady load of 100 milli amps, it should last about 22 hours. With a steady load of 1 amp, it should last about 2.2 hours, and so on.

## How long does a 3000 mAh battery last?

The “mAh”, meaning milli-amps per hour, gives the energy capacity of the battery. In your case, 3,000 mAh generally means you can expect to get 100 mA for about 30 hours usage, or 10 mA for 300 hours, or 1 mA for 3,000 hours.

## Is a 3000 mAh battery good?

## 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.
