Sam wanted to address a question from last weekend, about an early model Honda Hybrid. Sam says that most hybrids can go the entire lifespan of the vehicle without having to replace the battery. As for safety, Sam says that the battery is really small in a hybrid and as such, not only catch fire less often but aren't really that dangerous. The gas tank is more dangerous. But if the battery gets punctured, it could catch fire.
Myron has a hybrid vehicle with battery assist. Will it last? Leo says that early hybrids may not have been that sophisticated, but that he wouldn't worry too much about its battery life. They're designed for that. What's more important is how you keep your batteries within a set temperature range.
Are they safe if there's an accident? Leo says the battery was designed for impact and is why those hybrid cars are a little heavier. They absorb and deflect more impact energy. They also have crumple zones to absorb the impact. That makes modern cars far safer now than decades past.
