Perfect for Florida, south Texas and large parts of California.

For the cold weather problem, yeah. But still not intended for auto use.
One wonders what the makers of said battery would say if you told them
you were putting it into the enclosed space in the passenger compartment
of the Prius.

It isn't an 'auto', it is a hybrid. As you have already volunteered,
the battery only needs to be strong enough to 'throw some relays.'
BTW, I read one report of a Prius being started from two, 6 V.,
lantern batteries.

If you are going to invite a battery vendor, they should bring
datasheets for their battery AND measurements of the starting and
operating electrical load from the different Prius models. It would
also help if they'll bring some failure rate data so we can estimate
their life in a Prius. Better still, if they come prepared to discuss
how the Prius 12V electrical system works, again, we'll have an
interesting conversation. Best, if they want to suggest a specific
lawn tractor battery, many of which include a vent tube, that too
would contribute to the conversation. Do you have anyone in mind?

dude, it's an automobile. It still runs over public roads, for all
that's worth, for thousands of miles and in all sorts of weather--from
extremely hot to extremely cold. And it has to work like an appliance,
period.
A tractor battery was never intended or designed to be used in such an
environment. That's a fact.

Where I live tractor batteries are expected to, and do, perform in a
temperature range from -40F to +105F. That's a fact.
