Disconnecting batteries to work on engine - 6.0 diesel

[egpeil]

I'm kinda new. I bought a used 2004 E350 6.0 EB Quigley work can 4 yrs ago with the idea of doing a DIY SMB but due to unexpected situations it has spent most of its life (with me) in storage. I pulled it out last year and the EGR cooler ruptured so back into storage it went. Its back out, in my driveway and I'm about to start and EGR delete and several other things. It must be my inexperience with 6.0 diesel vans but the only way I we to disconnect the batteries is to drop them from their frame mounts. That sounds like a big hassle - is there another way? A battery isolator? Help please.

The factory battery boxs are rather easy to drop once you've done it a few times.

I know very, very few mechanics who ever bother with disconnecting a battery for service. I don't do it personally unless I need power removed for a reason.

Some frame boxes can be a beeotch, but unfortunately a lot of SMB's are laid out differently. Without pics or location of your batteries or separator it's hard to say.
