How long can electric car batteries be used? The lithium-The ion battery pack in the Tesla sports car is expected to last about 5 years or 100,000 miles. At that time, the packaging needs to be replaced at a cost of about $10,000. Of course, it's expensive, but the sports car itself costs $100,000, which makes the cost of the battery pack look affordable. There is no doubt that many car owners will prefer to replace the battery pack instead of buying a brand new sports car. Admittedly, the cost of battery maintenance will increase the cost of running any electric vehicle. The battery pack used in electric vehicles will be strictly controlled, so you will most likely need to take your electric vehicle to the dealer to repair your battery. One more thing to consider is that this is a relatively new technology at present. As electric vehicles become more common on the road, some of the high prices associated with electric vehicles will fall. But for now, the $10,000 battery for the Tesla sports car is one of our only reference points. Will the battery price of other electric cars be higher? Will they spend less money? Will the cost of replacing batteries in some electric vehicles exceed the cost of simply buying a new car? Only time will tell us.
