"Primary" batteries can produce current as soon as assembled, but once the active elements are consumed, they cannot be electrically recharged. The development of the lead-acid battery and subsequent "secondary" or "chargeable" types allowed energy to be restored to the cell, extending the life of permanently assembled cells.
The 2011 Nissan Leaf had lower range and smaller battery capacity than the 1999 GM EV1. Nevertheless, it was a hit. The 1999 GM EV1 production vehicle, powered by nickel metal hydride batteries, had a 26.4 kWh battery and an EPA range of 105 miles.
