Why does charge indicator light up in my car?

In California and some limited areas outside of California, a NiMH (nickel-metal hydride) battery version was offered, but only for lease . The NiMH version delivered a true 65 mile range at a steady 65 mph speed on flat highways (normal operation with some reserve; in comparison the lead-acid version is said to have a range of up to 65 miles with hard tires and careful driving. Actual range of the lead-acid Ford Ranger EV is less). The Ford Ranger EV controller electronics will allow strong acceleration even when in 'E' economy shifter mode. Thus a heavy foot will reduce the EV's range. The above the line cost of this vehicle (before manufacturer discounts and other public agency subsidies) was $50,000. Used Ford Ranger EVs have been sold from 25,000 on up, depending on the condition of the vehicle and the life of the pack.
