Everyone who asks about the cost of changing a Tesla battery forgets how much it costs to replace an engine and transmission in a gas car.
• BMW 2.0L Short Block (not complete engine): $13,117
• Model 3/Y Remanufactured Battery: $8,000
• Model 3/Y New Battery: $12-$14.5K
Still, people have no idea that Tesla batteries are designed to basically outlast the vehicle. Tesla states that their batteries are designed to retain 80% of their original capacity after 200K miles (321,000 km).
In the really rare instance that a battery is needed, the options are there, and they’re not crazy like people think.
