Battery for "74 TCS
« on: Tuesday,July 05, 2022, 12:39:23 PM »
Can anyone tell me what Battery I should be using in my car as I am about to buy one and drop it in for the first time. My parts store doesn't seem to have one that is compatible
Thanx

The battery specification in the workshop manual is obsolete but I was lucky enough to encounter a guy at the parts counter old enough to translate to a modern specification. I use a Group 51R. I don't know if they use the same battery group but you could also just get a Miata battery. Some of us use AGM batteries and the Odyssey PC680 is the usual choice.

The easiest, smallest, lightest drop in would be the Miata one BDA mentioned. They are AGM too. Plenty of power.
