Kia e-Niro’s 12-volt battery fails again! Jump starting, battery testing and talking about 12-volts

Why do electric cars still have a 12V battery - and why does the Kia e-Niro’s keep failing? In this first deep dive, I explain how the system works, common causes of flat batteries and how to avoid getting stranded. ────────────────── 📋 In this review • Why EVs still need a 12V battery • My ongoing Kia e-Niro 12V battery problems • Possible causes of repeated flat batteries • How Auxiliary Battery Saver works • Testing the battery with the Topdon BT200 • Ready Mode and Utility Mode explained • Which electric cars are affected by similar issues • Tips to reduce the risk of a flat 12V battery • The start of my 12V battery investigation Did you know electric vehicles still have 12-volt batteries? And did you know the e-Niro’s one is woefully inadequate? I’ve had problems with my 12-volt battery since I got the e-Niro. At first I thought it was because I had OVMS plugged in (a little box that gives me information about the car) but it’s failed even without that. I don’t know whether the problem is the battery itself, the e-Niro’s handling of it or something else, but that’s what I’m going to find out! I’ll discuss why EVs have 12-volt batteries (it’s actually a good thing), what you can do to help ensure yours doesn’t go flat (Ready Mode and Utility Mode), what the e-Niro does to keep it charged (supposedly) and much more. It’s a packed video, so get yourself a drink, sit back and shout at the screen when I inevitably say something incorrect. This is part 1 of the saga by the way. More will follow, I’m sorry to say!
