How to Measure Battery Capacity
If measuring in Wh (recommended for Lithium battery type), this covers a more comprehensive measurement of battery capacity, as it covers both the voltage and current. The formula to calculate WH is simply multiplying the battery''s voltage by its Ah rating e.g., a 12V battery with a capacity of 100Ah then has a total capacity of 1200Wh.
How to Measure Battery Capacity
This method is useful for accurately measuring battery capacity without the need for discharging the battery. However, it requires specialized equipment, such as a spectro, to perform the measurements. Factors Influencing Battery Performance When it comes to measuring battery capacity, several factors can influence battery performance.

Measuring current with shunt resistors
A shunt is a low-value resistor used to measure current – it is therefore also referred to as a current-sense resistor. The shunt typically connects in series so it carries the current of interest. A voltage measurement device then connects in parallel with the shunt. The current through the shunt generates a voltage drop that is measured.
