Car Ownership

C-Class Power

The C-Class Mercedes is something of an institution and multiple generations of them are plying SA's roads. If you are the proud owner of a C-Class from the 2012 model year onwards, your luxury sedan may be in need of a new battery if it is down on its much needed electrical power.

You may want to try your hand at replacing the battery yourself and save a trip to the local battery centre.

We are going to show you where to look and how to go about changing yours in just a few easy steps.

 

You will need:

 

  • A new battery of correct size and amperage
  • 10mm, 13mm, 14mm socket and socket wrench

 

Let's get started!

 

  1. Open the bonnet and locate the plastic cover just below the windscreen.
  2. Remove the plastic cover by unclipping the 3 clips that hold it down.
  3. Once the battery is revealed remove the red plastic cover from the positive terminal.
  4. Using the 10mm socket, remove the negative terminal and then the positive terminal.
  5. Using the 13mm/ 14mm socket remove the battery hold-down bracket bolt (on the side of the battery)
  6. Remove old battery carefully
  7. Install the new battery and replace everything in reverse order.
  8. Ensure the vents are properly connected.
  9. Replace the cover

 

Be sure to test everything before reinstalling all the cover panels to avoid trouble down the line.
