Just like a conventional starter battery, a hybrid battery needs to be exercised or it will decay until it is no longer able to start the car. All too often we hear about a hybrid car that was left sitting for an extended period of time and now has hybrid battery problems. The owners usually say the car was working fine prior to the extended downtime and are confused about what happened. The simple fact is that batteries will self-discharge over time. By giving the car regular exercise, at least once a month, you can insure that your hybrid battery stays charged.
