How to check your car battery | CarTipsandmore

Simple methods of CarTipsandmore

1. Take the Battery inspection
   • If there is corrosion on the battery terminals, remove it with a wire brush and apply copper grease.
   • If you see any damage on the case, the battery should be replaced.

2. Use the gauge to check the electrolyte level

   Remove any dust or dirt from the gauge and look at its color:

   • Green means the electrolyte and charge levels are normal.
   • White means the charge is low and the battery needs to be recharged.
   • Redmeans that the acidity of the electrolyte has increased and the water level has decreased.
   • Make sure the battery terminals are disconnected.
   • Add distilled water if needed.
   • Please wear rubber gloves when working with the electrolyte: skin contact can lead to chemical burns.

3. Check the electrolyte level using the special markings on the battery case
   Make sure the electrolyte level is between the „min“ and „max“ Marks is.

• Make sure the battery terminals are disconnected.
• Add distilled water if needed.
• When working, please wear the Electrolyte Rubber Gloves: Skin contact may cause burns.

4. Check the electrolyte level with a glass tube if your battery doesn't have level markings

• This only applies to batteries that are also serviceable.
• Check the electrolyte level of each cell.
  • Park the car on a level surface. Clean the battery cells of dust and dirt.
  • Remove the cell cap and insert the tube.
  • When the tube reaches the lead plates, fill it up and remove it.

  • Replace the cell cap.
  • The level of electrolyte in the tube indicates its level in the battery.

• Make sure the battery terminals are disconnected.
• Add distilled water if needed.
• Please contribute to the work the electrolyte Rubber gloves: Skin contact can cause chemical burns.

  

  5. Check the electrolyte density
     • Park the car on a level surface. Clean the battery cells of dust and dirt.
     • Remove the cell cap and insert the hydrometer tube.
     • Draw a complete sample of the electrolyte into the hydrometer. The float should float freely in the liquid.
     • The mark where the electrolyte meets the scale on the float shows the electrolyte density.
     • Carefully release the electrolyte back into the battery.
     • Replace the cell lid.
  • Make sure the battery terminals are disconnected.
  • This only applies to batteries that are also serviceable.“
  • Check the electrolyte density of each cell.
    6. Measure the voltage of the battery with a voltmeter or multimeter

       Set the multimeter to measure DC voltage and set the measuring range to 20 volts .
       Connect the black test lead of the multimeter to the negative terminal of the battery and the red test lead to the positive terminal. Read the multimeter reading.

       • When the battery is fully charged, the voltage should exceed 12.6 volts. A voltage of less than 12.6 volts means that the battery has less than 50% charge.
       • If the battery voltage is less than 11.6 volts, it means that the battery is completely discharged .
    • Make sure the battery terminals are disconnected.
    • If necessary, clean the binding posts with a wire brush before checking.

      

      7. Check charge the battery with a battery charge tester
      • Make sure the battery terminals are disconnected.
      • If necessary, clean the binding posts with a wire brush before checking .
      • The battery should be 6 to 8 hours before verification.
      • i Only run the check if the electrolyte level is normal.

      Connect the test leads to the negative and positive battery terminals:

      • Measure the voltage of the battery without load resistance.
      • If the readings are between 12.6 and 12, 9, the battery is fully charged.
      • If the readings are lower than 11.5, the battery is discharged.
      • < i class="as-icon as-icon--circle as-icon--info" style="background-color: #fffff"> Repeat the measurement a few times.
      • The verification should not take longer than 6 to 10 seconds.
      • Wait 3 to 5 minutes between individual measurements.
        • Measure the voltage of the battery with a load resistor.
          • If the readings are higher than 10.2, the battery is fully charged.
          • If the readings are lower than 7.8, the battery is fully discharged.
