Warranty & Returns

Product-specific warranty coverage is confirmed before order according to model, application and destination market.

Warranty confirmation

Warranty duration and coverage vary by product, configuration and sales agreement. The final warranty terms shown in the accepted quotation, invoice or contract take precedence over general website information.

Reporting an issue

Please contact us promptly with the order number, model and serial number, installation information, photos or video, and a clear description of the issue. Do not open or modify the battery unless instructed by our technical team.

Assessment and remedy

We may request diagnostic data or remote troubleshooting before authorizing a return. Depending on the confirmed cause and agreed warranty terms, the remedy may include technical support, replacement parts, repair or replacement.

Returns

Do not ship lithium batteries without written authorization and compliant dangerous-goods arrangements. Return shipping responsibility is determined after assessment and according to the sales agreement.
