Battery date code…

Hi all,
 
Does anyone know how the battery date codes are read? I have recently purchased a 2005 Swing for my wife. Runs great but can’t wait to tear into it over the winter. Last night I was installing a charging port for the battery and removed the battery for inspection.
 
It was a Honda OEM battery. The bike only has 11k km on it. Surely this can’t be the original battery. The bike starts fine and runs well. I was just curious. If this is the original battery then I will replace it over the winter for her.
 
There are two codes on the battery…
 
In white paint on the top : 1Q2448 (last digit could be a zero though).
Hot stamped into the plastic case : 04110446
 
Anyone got any insight?
 
Thanks,
 
Tim.
