Removal and reinstallation labour: Removal and reinstallation costs are not covered. Relocating the unit from its original installation site without Tesla's express written consent voids the warranty entirely.
Non-Tesla or non-certified installer work: Any storage, installation, commissioning, modification, repair, or opening of the external casing performed by anyone other than Tesla or a Tesla-certified installer voids the warranty.
Abuse, misuse, negligence, and force majeure: Defects or capacity shortfalls resulting from abuse, misuse, negligence, accidents, or force majeure events, including lightning, flood, earthquake, or fire: are excluded.
Failure to maintain internet connectivity or register: Tesla requires persistent internet connectivity for the remote firmware upgrades needed to honour the full ten-year warranty. Extended disconnection or non-registration may prevent Tesla honouring the full term, though a minimum four-year warranty applies regardless. Owners who did not buy directly from Tesla must register at tesla.com to preserve their entitlement.
Unauthorised modification: Any attempt to modify the Powerwall: whether by physical means, software, or programming: without Tesla's express written consent voids the warranty.
Normal wear and tear, cosmetic damage, and theft: Normal wear and tear, superficial defects, dents, marks, and non-excessive noise or vibration that do not affect performance are excluded. Theft of the unit or its components is also excluded.
Life-support and medical applications: Explicitly not warranted as a primary or backup power source for life-support systems or medical equipment. Tesla disclaims all liability for such use and may refuse service to units used in these applications.
No paid warranty extension available: No paid extension beyond the ten-year term is offered or referenced: the period is fixed at ten years from initial installation, with no advertised extension as at the document's effective date of February 2026.
