All Interstate automotive batteries are made by Johnson Controls, which also makes AGM motorcycle batteries.Johnson manufactures for Walmart, Sams Club, Autozone, and I think they make the Optima battery. Interstate might use other suppliers for some specialty batteries, including motorcycles, but it isn't easy to know which ones. Look at the country of origin. You might be able to tell from that. Interstate are all manufactured in the US or Mexico. Yuasa is made in the US and Japan.
