This post demonstrates the procedure to test the capacity of a battery. The test will determine and compare the battery’s real capacity to its rated capacity. A load bank, voltmeters, and an amp meter will be utilized to discharge the battery at a specific current till a minimum voltage is achieved.
A battery’s capacity can be estimated relatively accurately using a set of measurements and some complex math, but the most simple way to measure a battery’s capacity is to measure the power going into or out of the cell. Power going into the cell would be charge testing and power coming out of the cell would be considered discharge testing.
To measure battery mAh with a multimeter, you must set it to the current (amps) mode and connect the multimeter in series with the battery. By discharging the battery through the multimeter and measuring the current over a specific period, you can calculate the mAh capacity using Ohm’s law and the formula Q=It (Q = Charge, I = Current, t = Time).
Step-1: Ensure instrumentation is operational & properly connected to the battery for continuous monitoring of discharge voltage and current. Step-2: Measure the float voltage of the each cell/unit to ensure appropriate flotation. Step-3: Disconnect the charging current from battery.
You don’t need to worry about it. First, ensure your battery is fully charged. Next, find a reliable mah meter or multimeter. Then, connect the positive and negative terminals of the battery to the corresponding terminals on the meter. Once connected, the meter will display the battery’s mah rating.
For professional maintenance personnel, the capacity tester is the preferred tool for measuring battery capacity. By simulating the actual charging and discharging process of the battery, the capacity tester can accurately measure the capacity information of the battery.
Battery Current Sensors: Types, Problems & Solutions
If discrepancies are detected between the battery''s sensors and those of the motor controller, it can signal potential issues. Battery current sensors are also used to determine the state of charge in most battery management systems, making them critical for accurate energy management.

A 1700 mAh battery would be discharged in 3 hours by 1700/3 =~ 570 mA and in 4 hours by 1700/4 ~= 425 mA. So using about 500 mA and seeing how long it takes will give a measure of battery capacity. The current of the3 load in the circuit above is Iout = Vref/R1 so. R1 = Vref/Iout For an LM317 Vref = 1.25V so for 500 mA R1 = V/I = 1.25V / 0.5A ...

How to Measure Battery Capacity
Battery capacity is typically measured in units such as Ampere-Hours (Ah) and Watt-Hours (Wh). If measuring via AH, it represents the number of amperes of current a battery can deliver over the span of one hour. Theoretically, a 100Ah battery should be able to deliver 100 amperes in 1 hour before being completely discharged.
