Tesla’s Home Battery: Price, Lifespan, Availability, Alternative

3. Lifespan

Because it’s a new product, the lifespan of Tesla’s home battery can be determined only theoretically. The company offers a 10-year warranty, so you can expect it to work fine for at least that long. The battery’s deterioration will depend on how many cycles it can go through. According to Tesla’s warranty terms, the Powerwall 2 will have energy retention of 70% after 10 years if used as backup and solar self-consumption.
