Less than 30 rechargeable batteries died
The Korea Service Center notified that repairs were not possible
Is there a way to fix(repair) it? (in korea?)

Hi there, we are sorry for any inconvenience. We managed to find your case number through your forum account. And we notice that your battery is out of warranty and battery is non-repairable, therefore, our team send you a quotation for a replacement. Since the battery is non-repairable, we recommend you purchase a new one for use.
