My GL1500 would run out of juice lately if I muffed up the starting... I might get 2 sometimes 3 tries and after that, I'd need a jump.
So I checked the battery with a DVM; read 12'ish at a standstill. Dipped to 6-7V upon starting and then hung around 13.5 when running.
Obviously, it was a problem with the battery - at least. So, i replaced it with a Batteries+ sealed AGM (?) battery and all is well; dips to 11.5 for starting and pushes up and past 14v when running. Man, she starts right up now! Whew, sure glad it wasn't a stator problem.
I wondered about the age of the Yuasa that was in there. It was not a sealed battery and had a breather tube. The only code I saw etched in was on the front and was RC19EA. I found a doc of Yuasa date codes and if this is the Korean version (the only one that made sense given the letters in the code), the third digit, "1" indicates the year, but all the codes are supposed to be 7 digits, not 6.

Anybody have an idea how old this battery was before it gave up the ghost?
