That must be it. Dual terminal. According to the everstart website:
"A dual terminal battery has become very popular because it can be used for most top post battery applications along with side post vehicles such as GM. This way a consumer could take the battery out of their Chevrolet (side terminal) and put it in a Toyota (top terminal). Always refer to the battery selector or application guide to verify whether a dual terminal battery will fit properly."
On this topic, I've always wondered: does anyone make some sort of battery cable adapter which basically allows a side post battery to *also* attach to the top post on a battery? I'm not talking "instead of", I'm talking i"n addition to". The reason I say this is that I've had side post battery terminals get corroded out before, and then you obviously lose charge, can't recharge enough, etc.... leading to failure. If it had been attached to both the side AND the top of the battery, however, then there would have been a kind of failover redundancy. If one connection corrodes, you've got the other. Anyone know if that readily exists? Obviously, you could jerry rig your own, but why bother if it exists already.
