My dodge dually Cummins engine is very hard to start when cold. At home or camping with hookups I can plug in the block heater but what can be done when boondocking.

If they are that new You could always try and exchange them at Walmart. I'm sure you don't have the receipt but you never know they may just look at the date.650 ca is what the dealer told me was the replacement for my Dodge about six months ago. I bought some Die Hard batteries so far so good.
