How to charge Cadillac battery

If your Cadillac battery died because you forgot the lights or the radio on, it doesn't mean that you need to replace the battery. Instead, charge your Cadillac battery the using a 12-volt trickle charger to bring the battery back to normal operation.

This method will not only bring your Cadillac battery back to life but 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. 

What you will need
