Battery drain in cold weather

Corrosion on terminals is worse in winter. Follow all wires and clean and ensure tight connections. Baking soda and water will take off battery acid. Also do voltage drop tests and parasitic drain tests. YouTube these topics for help. Lightly sand all ground connections and reconnect.

Suggest buying another battery any battery will start in the summer if not starting when it’s cold time for a new battery.

Thank you for answering my question. Unfortunately, I have changed the battery about a month ago and it is still happening. I have cleaned the battery terminal connectors when I put in the new battery, but I didn't trace out the cables completely to check for corrosion. I will do that. However, I think that the parasitic battery drain may be exactly what is happening. One thing that comes to mind is a wiring connection for a trailer that I got from U-Haul. It clips onto the taillight wires with connectors that penetrate the insulation. Is it possible that this is causing the problem? I'm not much of a mechanic, so any help is sincerely appreciated!

Yes that was the exact issue a friend of mine had when he first bought his Chevy truck. Watch the parasitic drain videos and this will narrow your circuit down for you. You will see. Happy youtubing.
