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.
