Test Procedure
Measuring the charge level
  • Density of the electrolyte inside the battery is measured by a hydrometer.
  • The density should be corrected to the temperature of 27C. This will give you clues about the battery's condition.
  • Measure the open circuit voltage of your battery with an electronic voltmeter. If the value written down there is between 12.7 and 12.9 and the electrolyte density is around 1.280 g/cm3, your battery is fully charged and ready to be used.


Inspection of your car's electronic equipment
  • Check the electronic equipment of the car when a crippled battery has been brought or when mounting a new battery. The most common problem is overcharge or lower charge at car. Check whether the regulator charge shows between min. 13.8V and max 14.4V in a car working with 12V battery in stepped on the gas. If the values read on the tester, get your electronic equipment checked to a technician.
  • The coal in your march engine, charge generator or alternator can diminish after sometime. You should make them checked to a technician.
