Cadillac Recharge Dead Battery

What you will need

• 12 Volt Battery Charger

Smart charger recommended so that the battery doesn't get overcharged.

Procedure

1. Park your Cadillac and set the parking brake. Remove the key from the ignition or if you have a proximity key, keep it away from the car.

2. Open the hood of your Cadillac by pulling the hood release under the dashboard. Once you hear the hood pop open, you can stop pulling on the cable. Move the front of the vehicle and lift the hood.

3. Locate the battery. Some Cadillac vehicles have a plastic cover on top of the battery. Remove the screws that hold the battery cover in place. Remove the battery cover. 

4. You can also use the POSITIVE jump starting terminal to charge the battery. In newer Cadillac vehicles, it is recommended to charge the battery from this post. 

5. Connect the black clamp to the frame of the vehicle or engine. You can use a strut tower bolt, for example, or any unpainted bolts. Do not connect the black clamp to the positive battery post. 

6. Allow the battery to charge for a few hours. Monitor the vehicle for the first couple of hours and do not leave the vehicle unattended. If the battery overheats during charging, disconnect the charger. We recommend using a Smart Charger to prevent the battery from overcharging.

It can take several hours to fully charge a dead Cadillac battery. 

Warning

• Risk of fire! Do not leave the vehicle unattended. 

This method will bring your Cadillac battery back to life and ensure that the longevity of your battery is not damaged. Yes, you can always jump-start your Cadillac with a jump box or another car, but doing so can have an impact on the life of the battery.

When using your alternator to charge a completely discharged battery can trigger low voltage fault codes in various modules. If you have the time, we recommend charging a dead Cadillac battery following the directions below.
