Common Questions on Power Battery Repair
What happens to the battery warranty after it expires? What if the 4S shop isn't authorized? How long does repair take? How can I verify authorization authenticity? Here are clear answers to these common questions.
Out of Warranty & Full Unit Replacement
Can a power battery be repaired after the warranty expires? Is replacing the entire pack mandatory?
Out of warranty doesn't mean you must replace the entire pack. Most issues like pressure differential, single module failure, or enclosure damage can first be diagnosed to determine whether a module repair or full pack replacement is needed. Hengmang New Energy is located at No. 313 Chengjiao East 5th Road, Longquanyi District, Chengdu (Units 1-2). You can schedule a diagnostic test first before receiving a disposal plan.
Authorize and verify
How can I verify if a repair shop is authorized by the battery manufacturer?
Check three things: whether the authorization number matches the battery manufacturer's official channel, if the authorization is still valid, and whether the scope covers your type of issue. Request to see the original authorization certificate on-site.
Maintenance Cycle
How long does the repair take? Can I get my car back today?
Diagnostic tests typically yield results on the same day. Module-level repairs depend on parts availability, while full pack replacements and accident vehicles are scheduled based on actual production timelines. We recommend calling ahead to discuss your vehicle's condition for better scheduling.
