2020 Ram 1500

[kgr]

Battery drain only when cold. If my Ram doesn't run for an hour 2xs a day it will not start the next day. Days we do not go anywhere I let it run for an hour in AM and PM or it won't start the next day. Again this only happens below 40 degrees and its fine in summer. Still happens with brand new Battery and a brand new heater core. Any idea on what could be draining battery?

Welcome to the forum . There are quite a few things that can drain a battery . Is your truck stock ? Any changes at all ?

100% stock. And it only happens below 35 degrees. It will go from May thru Sept fine. Winter arrives and it cannot go a single day without being started twice a day for an hour each day
