To really test a battery capacity requires a timed test with a constant current load on the battery. Since the battery voltage changes as the battery gets depleted trying to use a fixed resistor type load leads to the load current getting smaller as the battery voltage goes down. The constant current load varies its effective resistance ...
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).
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.
Multiply the current reading by the time to arrive at the capacity of the battery in milliamp-hours. Finishing off our example, you have 200 milliamps then multiplied by fifteen hours. To sum up, your battery has a capacity of 3,000 mAh. You may be thinking, is a higher mAh rating better? Well, the answer to that question is, it depends.
To calculate the battery capacity in milliamp-hours (mAh), multiply the current reading by the time it took to exhaust the battery's energy. For example, with a current reading of 200 milliamps and a time of 15 hours, the battery has a capacity of 3,000 mAh.
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.
To really test a battery capacity requires a timed test with a constant current load on the battery. Since the battery voltage changes as the battery gets depleted trying to use a fixed resistor type load leads to the load current getting smaller as the battery voltage goes down. The constant current load varies its effective resistance ...
