I go up to the mountains and it gets pretty cold.

Was wondering what you guys use to plug those batteries in and keep them charged for the next morning.

Also, do you disconnect the batteries from the truck while charging them or leave them as is?

Thanks guys, It's been pretty cold up here lately, and I'd rather just plug in the charger instead of jumping it off the other cars up here. It gets old jumping a 3/4 ton truck from an Acura 3.2 TL.

 

Good batteries should have no problem with a cold night.

Dodge put two of them under the hood for a reason,
to be able to have enough power for the grid heaters, and turn over our beast of an engine, with power to spare.

My gauge reads below 10 while heaters are on then if I wait for a few seconds it'll go up to 14 or so. It would just be nice to have it as a back up.
