    My mum’s 2019 Toyota Yaris has to have its engine run every few days or the battery dies from just sitting on the driveway. It could be a faulty car battery but considering this car isn’t even that old and has barely driven 30k miles, it’s not doing so great. I discovered yesterday that my EV charges better after I’ve driven it around and the battery’s warmed up a bit. The car goes a bit haywire when you cold start so it seems like it needs some prep time before a drive.

      You probably have some parisitic power draw somewhere, my old Ford focus had the same issue. Was just a bad relay causing a fan to run when the car was off.

      Some car batteries only last 3 - 5 years. It might be due for a replacement. They are fairly easy to change yourself too if you want to keep the costs down.

        Also depends on the environment. Down here in central Texas you can’t expect the el cheapo batteries to last more than 2 or so years because the summer heat is brutal on them.

      Yes it does. You car (almost all EVs) slowly precondition the battery while driving. Many newer cars optimize the battery temperature when you add a charger to your navigation to have the optimal temperature once you reach it. If you know you need to rapid charge and the drive is short, it’s usually a good idea to add it to your navigation as the car will then maximize the heating/cooling before you get there, whereas with normal driving it would do this slowly to minimize drain.

      I had to rapid charge with a frozen battery once. Not a fun experience.
