Battery Life, Replacement, Safety

Batteries Last Several Years

  • Early EV Nickel-metal hydride (NiMH) batteries have been shown to last 100,000+ miles.
  • Newer EV batteries are Lithium-ion; manufacturers are providing warranties for 8 years/100,000 miles.
  • Both NiMH and Lithium-ion batteries show potential for alternative uses beyond the life of the car.

Battery Recycling A Priority

Manufacturers take battery recycling seriously:

  • According to the U.S. Environmental Protection Agency, even conventional lead-acid batteries have had a high recycling rate -- 98%. The trend is expected to continue with all types of EV batteries.
  • Metals in EV batteries are even higher in value than lead-acid batteries -- an even greater incentive to recycle.
  • Because of the chemical content in EV batteries, it is illegal to place them in a landfill.
  • Research is being conducted on the best way to recycle Lithium and to repurpose Lithium-ion batteries.

Replacing EV Batteries

Replacing a battery can be expensive, but automakers are providing alternatives to new car owners, including:

  • Battery warranties of 8 years/100,000 miles, which cover the average life of a car
  • Battery leasing programs. Check with your vehicle manufacturer for more details.

Are EV Batteries Safe?

  • Tests show that EV Lithium-ion batteries are designed with newer, safer chemical content and are built to prevent such hazards as thermal runaway, which years ago, and in rare cases, caused devices such as laptops to catch fire.
  • EV battery research and testing continue to ensure their safety.
