The average battery life of a Honda hybrid is 10 years or 150,000 miles, as reported by Autos.com. Under ideal conditions, which are rare, the battery can last as long as 30 years.
The Honda hybrid's battery comes from the manufacturer with an 8-year, 80,000-mile warranty. To extend battery life in hybrid cars such as the Honda hybrid, drivers who practice defensive driving can shift the transmission into neutral and coast to a stop rather than braking. The kinetic energy created by the car's coasting helps to charge the battery. Avoiding rapid acceleration after stopping at traffic lights also helps to extend the battery life in a hybrid car.
