Battery serial numbering system was changed for batteries produced after 11th Dec 2009 for internal management reason. However, it has been rolled back to the original system since Feb 2010.
*P/N and S/N are indicated inside the battery socket.
Original Battery Numbering System
Batteries were recorded according to the manufacture date. Ex) 0906 means it was manufactured in June 2009.
Problem - If batteries are stored in warehouse for a reasonably long time, the numbering system may lead the customers to misunderstanding. They might think the battery’s guaranteed life (normally 6 months) time has been expired and induces unnecessary management.
Modified Battery Numbering System
Use alphabet instead of numbers. Ex) AIL for batteries manufactured in Dec 2009.
Using alphabetical serial number eliminates the problem of the original system.
Effective since 11th Dec 2009

Current Battery Numbering System (July 2010)
Current battery numbering system has been rolled back to the original system since Feb 2010 due to alteration in national KC certification.
Battery serial numbers are recorded according to the manufacture date.
