In some trucks. There is an option for a block heater and battery heater for cold temps.
A lead acid battery will freeze solid if it doesn't have a charge in it. 2 yrs ago. I had to replace 4, 6v batteries in my motorhome because the batteries froze and broke the cases. The motorhome was sitting at a RV dealer waiting on to be repaired. It sat from Nov to Feb in Cleveland. No way for me to keep the batteries charged.
