Warranty Registration
Create a product record using the exact model, serial, seller and purchase information shown on the product and transaction documents.
Before You Register
Use accurate and readable records
Registration helps connect the customer, product, serial, seller and purchase date. It does not extend the warranty, replace proof of purchase or guarantee coverage for every future issue.
Submit information only for a genuine product purchased from STH or an identified authorized channel. Keep the original invoice, warranty document and product labels.
- Exact product model and serial
- Customer name and active phone number
- Purchase date and seller identity
- Invoice or receipt reference
- Vehicle and charger information where relevant

Helpful Answers
Frequently Asked Questions
When should I register?
Register as soon as possible after purchase when the product or warranty terms require registration.
What happens if the serial cannot be read?
Contact the seller or STH before altering the label. Clear identification may be necessary for verification and warranty.
Can I register a second-hand product?
Transferability depends on the model-specific warranty and written transaction terms. Registration does not create transfer rights.
Can I correct a mistake later?
Contact STH with the registration reference and supporting documents. Changes may require verification.
