EV batteries only last a few years.

**The Reality:** EV batteries are built for longevity, not quick failure. Most modern packs last 10–20 years with only gradual loss of capacity. Studies from fleet vehicles show less than 10–15% degradation after 150,000 miles (240,000 km). That means the majority of EV drivers will never need a full replacement within the vehicle’s usable life. You can model this yourself using our Battery Health Estimator .

Replacing an EV battery costs more than the car itself.

**The Reality:** While batteries were once extremely expensive, costs have fallen nearly 90% since 2010. Today, full pack replacements for popular EVs typically cost between $5,000–$12,000 (~£4,000–£9,500), well below vehicle prices, and many issues can be fixed at the module level instead of replacing the whole pack. Automakers still provide 8–10 year (100,000–160,000 km) battery warranties as standard, and costs continue to decline as scale grows. Read our guide on replacement costs for more details.

EV batteries suddenly die once they reach a certain age.

**The Reality:** Battery degradation is predictable and gradual — you won’t wake up with a ‘dead’ pack. On average, EVs lose 1–2% of capacity per year. A 300‑mile (480 km) car might still offer 240 miles (385 km) after ten years, more than sufficient for commuting and daily needs.

Fast charging destroys EV batteries.

**The Reality:** Frequent DC fast charging slightly increases wear, but modern EVs use advanced thermal management. These systems regulate voltage and temperature to keep batteries within safe operating ranges. Millions of drivers fast‑charge regularly and manufacturers still honour warranty claims — occasional rapid charging is normal and safe. Learn more in our degradation guide .

EVs don’t work in hot countries like Australia or the Middle East.

**The Reality:** Cooling systems in modern EVs ensure batteries are protected even in extreme conditions. Taxi fleets in Dubai, California, and Israel have covered hundreds of thousands of miles in 40°C+ (105°F) temperatures without mass battery failure. Thermal management is leagues ahead of what early EVs offered. India’s rapid EV adoption, with vehicles from Tata, MG, and BYD operating in 45°C+ conditions, is further proof modern EVs thrive in hot climates worldwide.
