When rated in conformance with SAE Standard J537 (September 2000) the batteries shall provide a Reserve Capacity (duration of 25 ampere current flow) at 27° C (80° F) for no less than 135 minutes.
Battery or batteries may be mounted either in the engine area or outside of the passenger/driver area in a separate battery compartment.
