Honda hybrid battery life is specified, by Honda, to be at least ten (10) years, or 150,000 miles of use. Under ideal conditions, the type of battery used in the Honda hybrid could last as long as thirty (30) years. However, automotive use is not ideal. The warranty supplied by Honda covers the hybrid battery for eight (8) years or 80,000 miles, whichever comes first. Honda hybrid owners living in California have their warranties automatically extended to ten (10) years or 150,000 miles, whichever comes first. There are companies that rebuild hybrid batteries, and they can be found at RE-INVOLT TECHNOLOGIES and hybrid-battery-repair.com.
