A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
The amount of current a battery can supply is determined by several factors. The first factor is the battery’s voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
A battery produces an electric current when it is connected to a circuit. The current is produced by the movement of electrons through the battery’s electrodes and into the external circuit. The amount of current produced by a battery depends on the type of battery, its age, and its operating conditions. Is a Battery AC Or DC Current?
If you only need the battery for a short period of time, it won’t need to supply as much current as if you were going to be using it for an extended period of time. Finally, you need to consider the temperature. Batteries perform better in cooler temperatures and can supply more current in those conditions.
Most batteries produce DC power, but some, like those in laptops and cell phones, use AC. The type of current produced by a battery depends on the chemical reaction taking place inside the battery. Batteries are made up of three parts: an anode, a cathode, and an electrolyte.
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.

I have always been confused when it came to how much charge does a battery charge. Let''s say, a phone battery: It says 1900 mAh @3.7 v. Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?
