To verify if a repair shop is authorized by the battery manufacturer, check these three things: whether the authorization number matches the official channel, if the authorization is still valid, and if the scope covers your specific issue.
Authorized service centers should leave the authorization certificate on-site. Customers can request to see the original document directly, rather than just viewing a photo on the wall or accepting verbal claims.
Additionally, the filing for motor vehicle repair operations is a verifiable business qualification. Hengmang New Energy holds authorization from 11 battery manufacturer after-sales service stations and has completed the Class II motor vehicle repair operation filing (filing number: 511227), both of which can be verified on-site.
If the other party avoids providing an authorization number or cannot specify the scope of authorization, proceed with caution.
