Rich and All: The 1955 AMA specs state the standard battery for the C300 is an Auto-Lite 2H-135-RD. Optional is the Willard MW-2-135-R. These have 19 plates per cell and a 135 Amp. Hr. rating. The 2H is an SAE designation. Now, regarding Gloria's noting of the 1960 AMA specs using Autolite instead of Auto-Lite. I checked the 1961 and 62 AMAs and they also use the non-hyphenated version. However, the 1960 service suppliment continues to use Auto-Lite. The picture of the battery in that publication is just not clear enough to make out the hyphen. In 1961, both the AMA specs and serv.suppliment use Autolite, while the Service Manual uses Auto-Lite! 1962 is the same with the hyphenation, but the AMA specs add an optional battery---a Gould-National. By 1963 there are no more Auto-Lite/Autolite batterys listed. Instead, Mopar is stated to be standard. However, when mentioning other electrical items like coils, Auto-Lite is again used in the service Manual. AMA sticks with Autolite. Finally (for me, anyway) Autolite/Auto-Lite seems to have disappeared in 1964. Batterys are listed as "various", and when talking about other electrical items, only the names Chrysler, Essex, and Prestolite appear. This is compatible with what George Riehl stated earlier about Auto-Lite becoming a Ford subsidiary about this time. I did not bother to look at the parts books----think I spent too much time on this already!!! Hope this is of some help to somebody!

I have those but can not currently access them. Anyone else?

But, I'd like to take this opportunity to again ask if anyone feels they really know for sure what brand or brands of 6-Volt, positive ground orientation batteries originally came in 1955 Chrysler 300's.
