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.
Measure the current: Use a data acquisition system or a microcontroller with an analog-to-digital converter (ADC) to measure the current flowing in and out of the battery. Integrate the current over time: Integrate the measured current over time to obtain the total charge transfer (in Coulombs).
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 energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
It’s important to know what the initial current is because it can help you determine how long the battery will last and how much power it can provide. The initial current is affected by a number of factors, including the type of battery, the age of the battery, and the temperature.
Electric current, the rate at which charges move along a conductor, is measured in units called amperes, or amps. The amount of current in a conductor can be measured with an ammeter. Just like a rock poised at the top of a hill, electrical charges can have potential energy, the energy of position.

If you only have periodic voltage measurements and the load current is small, you can approximate the state of charge of the battery with a SOC-OCV (state of charge - open circuit voltage) graph. You can probably find this graph for whatever chemistry battery you have and find the SOC that corresponds to a given voltage.
