Warranty comparison
Tesla vs BYD
The same four questions asked of both: how long on parts, how long on labour, what has to be registered, and what has to stay true.
Checked 30 July 2026
On warranty terms
BYD
Asks less of you across labour, conditions and term length.
On warranty terms alone, BYD asks less of you. Neither pays toward labour on the lines in this catalogue, so the truck roll is yours either way.

What separates them
- Neither pays toward labour on the lines in this catalogue, so the truck roll is yours either way.
- BYD attaches 1 condition to its full term. Tesla attaches 2, and an unmet condition shortens the term without telling anyone.
- Both carry 10 years on parts, so the parts term is not the thing that separates them.
Tesla
Checked 30 July 2026
Powerwall is registered with Tesla at commissioning, so there is nothing to file later. Connectivity is the condition that matters: the 10 year term needs the unit to stay connected to the internet. If the connection drops and is not restored within 45 days of Tesla's written request, cover ends at 48 months.
Powerwall registered with Tesla at commissioning
Connected to the internet: the 10 year term needs ongoing connectivity, otherwise cover can drop to 4 years
BYD
Checked 30 July 2026
BYD has no registration at all. The trap is the start date. Without written proof of delivery, the 10 years runs from six months after production, which can quietly burn months of cover before the battery is switched on. A delivery note moves the start to delivery plus 30 days.
Delivery note kept on file: it moves the warranty start from production date + 6 months to delivery + 30 days
