On the really cold days if u can leave a small lite burning next to ur battery,truck will be much easier to start.Occasionally a battery will have one bad cell,will check "normal" but will fail when u load it,thus the suggestion that u turn ur lites on for 30 seconds and then try cranking the truck.If the battery drags,probably a bad cell.Also if u r expecting a series of below freezing days,changing to 5w-20 might not be a bad idea.BJ
