To safely replace your own battery it is important to remember that you safety is paramount, wearing protective eyewear and gloves to minimize risk if battery fluid does fall.

  1. Put on your protective safety gear
  2. Ensure the car is in a well ventilated space or outside, if possible. This will minimize risk of explosion of the gases emitted for the faulty battery, if you are around any sparks.
  3. Lower the driver’s window enough to access the ignition keys via window.
  4. Turn off the engine, place into a neutral gear or park position, and put on the handbrake.
  5. Place memory minder into the cigarette lighter socket, and turn ignition key to turn the radio on.
  6. Remove the negative terminal first, then positive terminal and wrap the terminal securely in a rag to insulate from shorting to ground. (This precaution is necessary to avoid potential damage to the wiring and or electrics/electronics, as a terminal will be alive)
  7. Remove the hold down clamp, and carefully remove the battery, take note of the battery terminal positions, both positive and negative.
  8. Corroded steel parts should be cleaned and neutralized (Use bi Carb Soda), dried, and painted.
  9. Terminals should be thoroughly cleaned.
  10. Cable and starter motor connections should be checked and tightened if necessary. If you do not know what this is call or visit one of our Service Centres.
  11. If terminal clamps or cables are badly corroded, they should be replaced. Please call or visit one of our Service Centres.
  12. Clean the battery tray (similar to step #8); make sure no objects or sharp items can cause damage to the battery case.
  13. Check the height of the replacement battery to ensure there is sufficient bonnet clearance, to avoid terminals shorting/fouling on the closed bonnet.
  14. Place the new battery in the tray, ensuring it sits level and that terminal posts are positioned in the same position as the battery being replaced.
  15. Replace and tighten hold-downs securely so that the battery cannot move in the tray. Do not over-tighten as this can distort the plastic battery casing. Be sure to check that radiator fan, hoses and drive belts do not make contact with the battery.
  16. Re-fit cables and tighten terminals, (do not over-tighten) ensuring that the negative ground terminal is connected last.
  17. If a spark occurs during reconnection of the negative terminals, have an auto electrician check for a current drain at your earliest convenience or call or visit one of our Service Centres, tighten all connections. Note: Do not over tighten.
  18. Never hammer terminal connections onto battery posts, as this can damage the battery terminals or cause internal damage to the battery.
  19. Apply a coating of battery terminal protector or grease to the posts and bare cable connections.
  20. Carefully remove memory minder from cigarette socket or OBD port and start engine, check that charge warning indicator extinguishes, and the charge gauge (if fitted) shows a normal level.
  21. Check all radio and clock functions, to ensure no memory loss has occurred.
