R59 date code

[Ls6 Ragtop]

Hi Dave,
Not on service batteries. Regarding 1967 dated batteries, the year was designated differently in that the year was catagorized by the first character. This type of date coding was used through the 1969 production run.
If this battery was dated 1967 the first character would be the letter L.
They used a number for the second character which was for the month of production.
The third character would still denote the assembly plant of the battery.
If this battery were Sept. 10 1967 dated it would look like this- L9T 10
The Anderson plant used the letter T from 1955-1972.
Regarding 1987 usage, I do not have codes for batteries produced after 1979, but do not believe the R59 was still in production then.
I bet if Sam looks closely at the label on his battery it will confirm the Sept, 1977 date.

Sam,
The R59 was the common battery used on 1969 SS Chevelle without T-60 HD battery .
The T-60 option used an R69 top post battery.
Hope this helps clear this up.
