Hi All,

I did a search on this and didn't find what I was looking for. I just bought a new 2007 Ram 2500 with the 6.7L CTD. I just noticed today as I was changing out the 'break-in' oil that there is only 1 battery installed. The tray and wiring is there for the second battery, but only the drivers side battery is there. Is this right? Or did the dealership pull a fast one on me? Someone please let me know what is supposed to come with the truck before I jump someone's a$$ at the dealership.

Thanks!!!

 

WTF!?! Get on the phone. Your truck should definitely have come with TWO batteries!

 

This is my first time owning a diesel. Can someone explain to me why these trucks need two batteries?

 

i think they need both due to the current draw for the starter at startup .. and in cold conditions i believe they are used to supplement some power draw for the intake air heater for easier starts.. but if i am wrong someone will correct it..

 

You definitely should have two batteries. One batt will probably do the trick in mild weather, but when it's cold you'll need 'em both.

 

Our startewrs pull a lot fo draw, turning our motors over are not nearley as easy as it is to turn say a 5.7 hemi. look at the size of our sarter and while it is turning it over there is a heating grid that is pulling juice as well. Get to the dealer get your battery and tel them they better give you a couple free oil changes as well.

 

Thanks everyone! I'll get the dealer on the phone today and get this straightened out.

 

wow what a bunch of sh*t
