car battery

I feel someday more gas cars may come with a electric charger cable which is use to charge a car's battery which electricity is used to power electric parts like lights, the air conditioner, Window wipers, power windows, stereo system, alarm, touchscreen tablet, self-driving computer systems...

No, I don't think many electric car owners will replace a battery on a very old electric car because a lot of people don't like to keep driving old cars for many more years because they look old, don't have as many cool features, old car parts can breakdown a lot, and the metal on the car maybe...
