  • Then, turn off the engine and re-measure the battery voltage without starting the engine. 
  • Monitor the parameters displayed on the voltmeter: 

  – If the indicator displayed on the meter is between 12.4 - 12.7V, the battery is still operating normally.  

 – If the voltage is from 9.6 to 12.4V, you need to charge the battery.  

  – If the voltage is below 9.6V, the battery is weak and about to fail, you need to replace the car battery. 

In case the car does not start for a long time or starts but after turning off the engine, forgets to turn off the key, leaving other devices on such as fans, lights, radio... consuming all the power in the battery causing the car to not start. restart, you need to restart the battery by using another battery, connect the positive pole to the positive pole, the negative pole to the negative pole of the car's battery and start the engine to charge for 15 minutes, then crank it. First step is to check the dinamo and battery. 

4. How to replace car battery 

  • First you need to prepare a new battery, check the new battery voltage. 
  • Return the key to the completely off position. 
  • Proceed to remove the old battery in this order: remove the negative post first, remove the positive post later.
