The lifespan of a Powerwall battery depends on a variety of factors, including how often it's used, how deeply it's discharged, and how well it's maintained. According to Tesla, the manufacturer of Powerwall, the battery is designed to last for 10 years or more. However, the actual lifespan of the battery can vary based on usage patterns and environmental conditions.


In addition, Tesla offers a 10-year warranty on Powerwall, which covers defects in materials and workmanship.
