My ZR1 is 40 miles away and I'm going to buy a battery on the way.

Does anyone know the size?

Thanks

Just checked my 90 model. Group 75. Good luck.

I know it is a group 75 battery. I have an Optima in mine, however, it requires some minor modification to install. At the bottom you will see the physical dimensions of the battery to fit our ZR-1s. The info below was clipped from an Interstate battery link.

Hope that helps.
