2005 Mercedes-Benz CL65 AMG: Replacing the Battery
June 11, 2014
Taking out the old battery wasn't terribly difficult. You have to remove the cover and then a bracket that holds the battery in place. I did need a long extension for my socket wrench to loosen the bracket's bolt.
Granted, lifting a big and heavy battery like this out of a recessed hole isn't much fun for your back. Thankfully, there are two handles on the battery's top to make it (a little) easier.
Oh, and because there wasn't any power to the power opening and closing mechanism, the CL's trunk lid had a habit of slowly closing on its own due to gravity. It would seem the struts are a little worn. I used a piece of wood to keep it in place while I did my work.
Then I was off to my local Mercedes-Benz dealership to buy a new battery. What's that saying about there's nothing more expensive than a cheap Mercedes? Total cost with the core swap was $267.32
