The DC to DC converter is located at top right center of ICE compartment. Also the orange tubing is right next to it, pics are from MADMAX in the process of being repaired after hitting deer at the end of 2013. :sad: Needless to say CMAX turned into MADMAX. :rant2:

That's the inverter on top of ICE that converts HVB DC to 3 phase AC voltage when motors are using power and  3 phase AC to HVB DC when the electric motors are producing power.  The DC/DC converter is in the rear near the HVB.  It converts HVB DC to 12V DC.

I have 2013 Cmax which I purchased in Feb 13. Looks like the 12v battery(Group 67R orginal) is going bad. Guess the HV pack is the only thing saving me if I drive on regular basis. I keep one of the Lithium jump starters in vehicle just in case.  Has anyone tried the 90/T5 battery that Sam's sells to use in their vehicle? Looks like it has the same size but bigger CCA and seems to be cheaper ($105.88 in my area) alternative. Looks like Interstate recommends on their web site. Let me know.

Isn't group 90 longer than the bxt67r?  The length of the 90/t5 is about 1 1/4 inches longer per Interstate and Motorcraft specs than the 67R.  See if there's an extra 1 1/4 in the battery compartment.  Even if it fits in the compartment, cables could be an issue.

Interstate site says length of 67R is: Length  9 1/8....Time to open and look I guess.

 

Edit: after looking at battery, dont think it will work as they give you no extra room.

Yes, I think you're pretty much tied into getting the Motorcraft battery, that's why I just let the dealer do it, with special discount from dealer at the time the battery from dealer was the same price as Amazon, plus I would have needed to go buy a few extra tools and then spend 30-45 minutes of my time in 32F weather outside.

I did it myself, connected jumper battery under the hood, then removed old 12v batt. and put new one in, really easy. :)
