How to Change a Car Battery Safely. Connect a Memory Saver. To change a car battery without losing settings, you will need to connect a memory saver to your vehicle. Disconnect Battery Cables. Remove Old Car Battery. Clean Out Any Corrosion. Install New Car Battery
Can you turn the key ? ON - OFF Who changed the battery ? When you change a battery you need to use an external battery supply till new battery is in , so this doesn't happen ! You may need to have it towed to the dealer to have a module reset done ! Battery Disconnect or Replacement Problems
Which battery did you change? There are two batteries installed on your vehicle. There is a battery in the trunk on the right side which is called the systems battery which supplies power to the electronics of the vehicle and the second battery is under the hood near the bottom of the windshield. The battery under the hood is the starter battery. Check and/or replace that battery and let me know what happens.
You need to keep a supply to it. You can buy various devices that plug into your cigar lighter. The quite simply have one of these square 9 volt radio type batteries in them. This keeps power on while changing battery. You could easily make something up with one of these batteries and a couple of leads going to the terminals after loosening the bolts. Be careful though and make sure your wires are secure so the do not come off while wrestling with the battery. Cheers John
