The amount of current in a battery depends on the type of battery, its size, and its age. A AA battery typically has about 2.5 amps of current, while a 9-volt battery has about 8.4 amps of current. Batteries produce direct current (DC). The electrons flow in one direction around a circuit.
If you can calculate the amp draw (or load current), you can use the Battery Life Calculator. Battery Life Calculator. You just input the battery capacity that’s written on your battery (in Ah) and the calculated amp draw (load current), and the calculator will tell you how many hours the battery will last.
This calculation shows that the battery will power the device for approximately 1.85 hours before needing to be recharge. How accurate is the Battery Run Time Calculator? The accuracy of the Battery Run Time Calculator depends on the precision of the input data, including the battery's capacity, voltage, and the device's power consumption.
The total charge a battery can store, measured in milliampere-hours. The nominal voltage at which the battery operates. The rate at which a device consumes power, measured in watts. The estimated time a battery can power a device before being fully discharged. Let's go through an example to demonstrate how the Battery Run Time Calculator works:
The "amp" in amp-hour refers to the current, or flow of electrons. The "hour" refers to the time that the battery can provide that current (in hours). For example, if a lithium battery has an 100 amp hours, it can provide 1 amp of current for 100 hours before it is depleted. Or, it can provide 10 amps for 10 hours, or 20 amps for 5 hours.
C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. Discharge current.
