A serviceable 36-volt nickel metal hydride battery is located behind the rear seat, beneath the load floor. The battery contains 3 separate 12-volt cassettes which are wired together in series. The cassettes are serviceable and weigh approximately 10 pounds each. The cassettes will not be serviced individually, they will be replaced as a set of 3. Each cassette contains 2 non-serviceable, 12-volt, 8.5 amp-hr modules which are connected in parallel using bus bars.
