Tech Primer: Why 12-Volt Batteries in Electric Cars Get Sick -- And How To Keep Yours Healthy

Today's video is inspired by a problem we had this morning at Transport Evolved's headquarters: namely a flat battery on our 2013 Nissan LEAF Staff Car. But we're not talking about the main traction battery here: we're talking about the 12-volt accessory battery that's used to provide power to lights, radio and on-board computer -- as well as start the car. Just like the 12-volt starter battery in an internal combustion engined car, having an issue with your electric car's 12-volt battery can be extremely frustrating. But what causes the problem -- and how can you fix it? Watch the video above to find out.
