How Often Should the Hybrid Car Batteries be Replaced

Hybrid car batteries are designed to last about the lifetime of the hybrid vehicle. This means that except under rare circumstances, a hybrid car battery should not have to be replaced by an owner. The lithium-ion battery that is a standard type for all hybrid vehicles provides the power necessary to increase the vehicles overall gas mileage and fuel efficiency. With the plug-in hybrid technology, the car stays at its maximum output when the car is properly charged.

Lithium-Ion Technology

As lithium-ion battery technology has improved, the hybrid car battery has become more a permanent part of the vehicle that requires only ongoing service by the owner. This ongoing service is in the form of charging and keeping the battery at its maximum charge level. Batteries are designed to provide a minimum of 100,000 miles of performance and more, which for most drivers is beyond their ownership period, especially if the vehicle is traded-in within 5 years.

When a Replacement May Occur

Replacement will only take place in those rare circumstances when the battery fails to properly charge or work as required. In those circumstances, a certified mechanic should change the battery and handle the proper disposal of the old one. This should be done in order to prevent the exposure of any toxic materials within the battery into the environment. Also attempting to do the replacement yourself may cause you to do some harm or damage to the vehicle that will require an experienced mechanic and several thousands of dollars to fix.
