How Long Will A 3000 Mah Battery Last. The determining factor is the number of shots that you fire. How many hours does a 3000 mAh battery last.
It is that simple. Watts are Amps times Volts so to convert mAh to Wh you divide by 1000 to get Ah and then multiply by 37V. You can calculate the battery life by dividing the capacity of the battery by the current required by the object.
This battery life calculator estimates how long a battery will last based on nominal battery capacity and the average current that a load is drawing from it.
In airplane mode your device can last up to 3 days on charge. Usually since electronic circuits usually consume current in the low milliamperes 20ma-50mA normal batteries will last hours and hours 50-100 hours since normally batteries have a battery capacity range of 1700mAH to 3000mAH. Its something a bit more standard for everyday activity. For a 18650 2500mAh 25Ah battery with a device that draws 500mA 05A you have.
