Varta provides advice on battery best practice

In this regular column, VARTA’s technical team demonstrates the capabilities of using the VARTA Partner Portal to accurately change a battery. Below is an example of the step-by-step fitting instructions that can be accessed from the portal and this month we look at a battery replacement on a Land Rover Discovery.


Before starting the battery replacement 

Where fitted, disable the satellite anti-theft system (by setting it to ‘maintenance’). Make sure the ignition switch is set to ‘off’. Before disconnecting the battery, switch off all the electrical accessories, bearing in mind the following recommendations:

  • Make sure you have the car radio security code, if provided
  • Bear in mind some data (e.g. time, computer trip, and the settings of certain accessories) will be reset to zero
  • Wait for the necessary power latch time required for the electronic units – the time may vary from five to 15 minutes depending on the vehicle
  • If the battery needs replacing, make sure the new one is suitable for vehicles with a start-stop system
  • It can take anywhere between four to six hours in standby mode (with the instrument panel switched off) for the system to reset
  • Once the battery has been replaced/disconnected, it is recommended to run diagnostics on the electronic control units and remove any faults found
