What is milliampere hour?
What is milliampere hour?
Glossary Term: milliamp-hour A measure of charge (or current flow over time). One ampere-hour (or amp-hour or Ah) is a current of one ampere flowing for one hour. The amount of charge transferred in that hour is 3,600 coulombs (ampere-seconds). A milliampere-hour (mAh or milliamp-hour) is a thousandth of an amp-hour.
What is ampere-hour of battery?
Ampere hours — sometimes abbreviated as Ah or amp hours — is the amount of energy charge in a battery that enables 1 ampere of current to flow for one hour. Another way of saying it is that 1 Ah is the rating indicating how much amperage a battery can provide for one hour.
How do I calculate amp hours?
Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours. If you are using a different voltage battery the amp-hours will change by dividing it by the battery voltage you are using.
How many mAh is a ma?
Ampere-hours to milliampere-hours table
Ampere-hours (Ah) | Milliampere-hours (mAh) |
---|---|
1 Ah | 1000 mAh |
10 Ah | 10000 mAh |
100 Ah | 100000 mAh |
1000 Ah | 1000000 mAh |
How long will a 3000 mAh battery last?
The 3000 mAh battery comes with the integrated SmartPower 3.0 technology. A single full charge can give you up to 1.46 days of battery life with moderate use and over a day with heavy use.
What does 120Ah mean on battery?
A 120Ah battery stores 1.2 times more charge than a 100Ah battery of an identical terminal voltage [that is 12V]. Hence a 12V 100Ah battery provides lesser power backup as compared to the 12V,120Ah battery. Also, a 100Ah battery is lighter in weight than a 120Ah battery as well as cheaper too.
What is 100Ah battery?
Ah rating of a battery indicates the battery capacity or the amount of ampere hours it can handle. A 100Ah battery means that the battery can supply a load of 100 amperes in one hour, or 50 amperes for two hours or 10 amperes for 10 hours.
What is mA in battery?
The term milliAmp is commonly used when specifying the capacity of a battery. For example, the capacity of a mobile phone battery (Figure 3) might be 3000 milliAmp – hours (written as 3000 mAh). This means the battery can supply 3000 mA for 1 hour or 6000 mA for 30 minutes or 1000mA for three hours etc.
