Battery testing typically covers several key aspects, including battery capacity, nominal voltage, charge and discharge performance, performance under high and low temperatures, as well as resistance to overcharging, over-discharging, vibration, and impact. These tests are essential to ensure the safety, reliability, and longevity of the battery.
Batteries produced by reputable manufacturers usually have a higher actual capacity than their rated values, often leaving a margin of 10 to 20 mAh. This ensures that even if some performance is lost over time due to aging or usage, the battery still meets the required standards.
To check the battery capacity, you can use specialized software designed for phone battery testing. This method provides a quick and convenient way to get an approximate value of the current battery capacity.
If you want to measure it manually, make sure the test is conducted under constant current conditions. Connect a resistor with a resistance similar to that of your mobile phone in series with an ammeter. Then, discharge a fully charged battery (4.2V) until it reaches 3.7V. Measure the current and record the time. For example, if the current is 200mA and the discharge lasts 4 hours, the battery capacity would be 200mA × 4h = 800mAh.
For more accurate and professional results, it's recommended to send the battery to a certified testing laboratory. There, advanced equipment and expert technicians can perform comprehensive evaluations to determine the true condition and performance of the battery. This is especially important for critical applications where battery failure could lead to serious consequences.
