This test can be performed with a simple voltmeter or multimeter, but a battery tester will determine this as well. Determine if your battery is within the healthy voltage range. Fully charged, it should read 12.6 volts or higher. At 12.4 volts ... No matter how you slice it 12.1 volts is low given the typical fully charged float voltage per cell at 20c is 2.1v / cell (and for a new battery tend to be higher like 2.2 v / cell). So 12.6 - 13.2 volts for a new battery is fully charged floating. Most newer batteries will be at 12.6v or more for many days after a decent drive.2. Crank up the engine. 3. Check the voltmeter reading. 4. Sustain the cranking time for about fifteen seconds. During this period, the voltage readings should be about 9.6 volts, or above. A voltage rating of about 9.6 volts is relatively good when it comes to the number of volts needed to start the car.
