Let's take a look at the steps to check the battery voltage.
When the battery voltage is detected, the vehicle should be at least at rest for 2 hours, and it will not start, load or unload within 2 hours.
When measuring the open circuit voltage between battery terminals with a battery tester, be careful to turn off the ignition switch. If the detected voltage is equal to or greater than 12.5V, this indicates that the battery is normal. But if the voltage is lower than 12.5V, then the owner is looking for a reason.
It is recommended that when testing, it is necessary to measure the battery voltage with a digital multimeter or a pointer multimeter. Because this measurement method has no load in the measurement circuit, the meter display value is not necessarily the actual voltage of the battery, so Causes inaccurate measurements.
The above is a small compilation of the method of checking the battery voltage, it is hoped that the above is useful to the owners. In fact, it is very useful to check the voltage of the battery of the car regularly, so that you can always know the safety of the car.
