Hi guys,

I have a 06 E350. I just replaced the main battery in the truck. Now I should replace the auxiliary battery. Where is it and how do I get access to it?

Thanks in advance.

You only need to replace it if it is bad.

It is located on the passenger side under the hood and below the cabin filter at the firewall.

Hi vettdvr ,

Thanks for your help. I had the "Visit Workshop" light came on with the battery logo. I figure I might at well change it since the batteries are already 4-year-old. I really don't want to get stranded anywhere. Call it cheap insurance.
