Factory installed battery

Looks like mine was one...learn something new here every day.

when the 440HP (E86) was added to your car's OPTION list, the group 27 battery (F25) was included

Mine's a true Canadian car, F25 battery, N25 block heater, but strangely enough, no rear defog... Must have been cheaper to get it dealer-installed, which could make sense as it was ordered as a demo...
@6bblgt , any info on percentages for JH23 also?

of the 38,091 V8 Challenger hardtops (JH23) built for US spec. (Y05) in '70 - ONLY 3.3% had the group 27 battery (F25) ~1,257 cars

I'm sure the "big battery's" installation rate for cars spec'd for north of the border (CANADA - Y07) was significantly higher

Mine was a F23-group 24 according to the build sheet-but it was also shipped to Calif.

@6bblgt you are indeed the man with the numbers. Thank you for yet another learning experience. I keep finding more and more facts on the rarity of my car because of your documentation.
