    Whoops! The terminals are top mount, not side mount like the OEM battery for my V Starr 1100 Classic. While I was able to secure the cables, it makes for an inelegant installation, which may stress the cables over time. I am looking into using some terminal adapters, perhaps the ones made by Odyssey? The OEM battery did indeed fit the space perfectly, and then – uh oh, a problem with the top mount. Not really the vendor’s fault, as the battery pictured clearly shows the terminals on the top. I guess I focused on OEM replacement, and figured that was that.
