With more than 300,000 Nissan Leaf electric cars on the road, some more than six years old, battery degradation is becoming more and more of an issue. The different rates of capacity loss are a topic of much discussion among Leaf owners, but it now seems likely that Nissan's choice of passive air cooling rather than active liquid cooling has contributed to faster capacity loss than in GM or Tesla electric cars. Now Nissan has announced a new option for Leaf owners, one that's considerably less expensive than buying a new battery pack off the shelf for an aging Leaf. DON'T MISS: Nissan Leaf...
