How long do most EV batteries last?

Most EV batteries are designed to last the life of the vehicle, typically 10-20 years or 150,000-300,000 miles, with a gradual loss of capacity over time. It is very rare for a battery to 'die' suddenly. Most manufacturers provide an 8-10 year warranty that guarantees the battery will retain at least 70% of its original capacity within that period.

Is it expensive to replace an EV battery?

While it is expensive, a full pack replacement is very rare. Costs in 2025 range from roughly $7,500 to $20,000 depending on the model. More commonly, individual faulty modules can be replaced for a much lower cost.

How can I maximize my EV battery's lifespan?

For daily driving, keep your charge between 20% and 80% (unless you have an LFP battery, which tolerates 100%). Limit the use of DC fast chargers to long trips, and avoid leaving the car parked for weeks at a very high or very low state of charge.
