The average Honda hybrid battery cost, from the Honda dealership is from $3,000 to $3,500. The batteries are designed to last for at least ten (10) years, or up to 150,000 miles. Battery charging is accomplished through regenerative braking, and is monitored by a power management system that is computer controlled. Batteries can be purchased used from dealers and auto salvage lots. However, they can also be rebuilt. The rebuilt battery is as good, and in some instances, better than the factory-supplied battery. There are companies that specialize in rebuilding hybrid batteries such as, hybrid-battery-repair.com and RE-INVOLT TECHNOLOGIES.
