How to Maintain Your Car Battery - It Only Takes About 30 Mins

Not something you need to do that regularly because most modern batteries are relatively maintenance free. But, when you do... here's a quick guide on what you do.

Before doing anything, ensure you've got the codes for reprogramming the stereo and other electrical systems that could be affected by loss of electrical power.

  1. If the terminals or clamps are corroded they may need cleaning. So, using a wrench, loosen and remove the cables from the terminals. For safety, always remove the negative (-) connection first and reconnect it last.
  2. Make a solution of baking soda and water and cover the terminals with it. It will bubble and turn brown. When this stops, wash it off with water and dry the battery using paper towels.
  3. Reconnect the positive (+) terminal then the negative (-) one and, to prevent future new corrosion, coat the terminals with grease.

If you need a new battery or simply some advise, contact your local HiQ centre.
