To measure a battery's mAh rating using a multimeter, you'll need a resistor to act as a load and a stopwatch to measure elapsed time. Milliamp-hours (mAh) are the units technicians use to measure a battery's useful operating lifetime, or how long the battery will last when it powers a normal electrical load. You can measure this value by discharging the battery through a known resistance and measuring the elapsed time.
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).
A reliable method for determining a battery’s milliampere-hour (mAh) is by consulting the manufacturer’s specifications or using a multimeter. Multimeters are versatile tools that can measure various electrical parameters, including mAh.
The 'mAh' in a battery stands for milliamp-hours. To determine the capacity of a battery in mAh, learn how to use a digital multimeter. Turn on the multimeter and switch its measurement dial to the direct current (DC) measurement setting, since all batteries produce DC current. The 'mAh' indicates the amount of charge the battery can hold when full.
Re: How to measure the mAh capacity of AA/AAA NiMH batteries using a multimeter? If they are 600mAh batteries then that means they can theoretically supply 600mA for 1 hour. You can't test this by just touching a meter (or any other test gear) on the battery for a sec and taking a reading.
To measure the battery’s life, you would need to divide the battery’s capacity by the current needed by the object it powers. For example, you have a mobile phone with two batteries: the first battery has a capacity of 1,000 mAh and the second battery has a capacity of 2,000 mAh. Your phone needs a current of 200 mA to function properly.
