Will the battery give the electric cars a range better than 250 miles??
I think that a 200 mile range with a recharge time of 15 minutes would be a winner.
and how long do they hold a charge with no interaction.
IOW charge the car and leave it for a couple of weeks or month and it works just fine.
also.
250? a modern car, not ecconobox, goes for about 350 to 400 miles...
