Batteries under the seat

Not acceptable.

Put them batteries outside under a battery box off the frame where they belong. You got chemical gases in several different forms that will absolutely kill you, try to destroy your eyes and so forth.

 

under the passenger seat.... my god are you mad? lets see some pictures of the setup so we can maybe help you when you move them. you need to get a battery box external to the cab, x1heavy is right, if they are inside they need to be vented externally which you need batteries that have a vent tube attachment, chances are you don't have that.

 

Hmmm, did freightliner even make a cascadia back in the 50's? lol

I seem to remember some type of truck that had batteries under the passenger seat and vented outside, can't remember what it was though.

 

Surely he means in a battery box outside on passengers side? I hope so.

 

Older Internationals had them that way
