I'm eyeing a used Lexus RZ 450e and diving headfirst into some reviews to help me figure it out. So, I stumbled upon this review saying you can’t warm up the battery before charging, even if you’ve got the sat nav working its magic. They’re saying this makes charging super slow in cold weather and on long trips. Is that actually the case, or is it just a load of nonsense?
