You need to prepare the following tools:


  • Battery charger (suitable for motorcycle batteries)
  • Multi-purpose electric meter (suitable for vehicles and household appliances)



Step 1: Charge the battery


To test the battery, first charge the battery with a charger, unplug the charger and wait for about one hour after completion. There are all kinds of car chargers in the market (every driver must have one to look at the door), but it should be noted that the power of a motorcycle battery is much smaller than that of a traditional car battery. If you use a car charger to charge a motorcycle battery, it may cause damage to the battery itself; change the angle, if youIt may take longer to charge the car battery with a motorcycle charger. Remember to pay attention when buying. (Some chargers can be applied to both motorcycle and car batteries, and the corresponding power can be adjusted freely when used, which is very convenient. )



Step 2: Test the car battery voltage


The price of multi-purpose electric meters is very cheap, and you can buy them for a few tens of meters at the most flat price. Multi-purpose electric meters are very convenient and can be used to test cars, motorcycles, trailers, and household appliances. They are cheap and have a long service life.


During the test, the meter is first set to 20 volts, and then the red cable is connected to the positive battery terminal, and the black cable is connected to the negative battery terminal, and the meter will display the static voltage of the battery.


In the stationary state, if the battery voltage is lower than 12 volts, it is time for you to replace the battery, otherwise you will most likely encounter the risk of dead power again.



Note that this is only one way to test the battery voltage, and the condition of the battery cannot be completely determined. If you have any questions about the performance of the battery, it is recommended to consult a professional garage technician for further inspection.
