Hi I have duel batteries in my truck that are dead after sitting all winter and need to jump them.what battery should I hook up to.
It’s a 2016 gmc 6.6 duramax
It’s not that cold in Surrey that two, 2 year old batteries would die. I live in the Kootenays which is way colder than Surrey in the winter and way hotter in the summer. The batteries in my 2007 Duramax lasted 8 years, actually they were still half decent, but it was time to change them, life was 1 year past usual life of a battery in our climate. I never plugged in the truck here in the winter, unless I go to the kids place between Banff and Calgary.
Now I’m not a Mechanic, and not even close. I know enough to get my self into trouble and that’s about it.
However two, 2 year old batteries die because the truck wasn’t run over the winter.... you have a large power drain someplace. The little scurity system in the radio, I don’t think would kill two basically brand new batteries, becuase the truck sat for 5 months.
I would be talking to a GMC teck, as well ensure all your cable connections are clean and tight, as a loose wire on either battery will help to kill a battery.
