Sodium-Ion battery
Just came across this vid from a rider (not a HD) trying a Sodium-Ion battery on his bike. Technology seems new and fitment is probably sparse at the moment.. But it has some benefits over Lithium and over AGM. Worth checking out and monitoring. $31 for a battery that out performs AGM is kind of hard to beat, but obviously still issues to work out. They do have a few that would fit my sportster but the poles are on the wrong side. Still, interested in trying this out.

Screw that warm up. Least from my experience, a false start on an older Softail TCb FI like my old bike caused a flooding condition that made the next cranking long and confusing. Sometimes making it necessary to give it some open throttle.
A few pounds lighter on a battery in a Harley is not even worth mentioning.
That low voltage would also screw with the regulator throwing high voltage out put to it.
On a modern car like some that have BCM protection may just sayI am protecting the electronics from low voltage and do nothing... which is a good thing if the voltage is starting at 12.1 and probably would drop way below 9.3..

I don't understand wanting to put anything other than the type of battery the vehicle came with when it has to be replaced.
It was made to use that battery.
Improve the tires or fluids or plugs or brake pads or whatever - if you want - - but that electrical system was made for the battery it was manufactured with.

But I can see the "well, there's your problem - you changed the type of battery" when taking it in for service for an electrical problem.
Whether real or not - it opens you up to that.
But yeah I've been told that crap with other "improvements" too like the rotors wearing because of ceramic brake pads or ignition problems because of iridium plugs, because it's not an American Elite Tire or OEM Harley oil.
But electrical problems are the worst. I just want to avoid any problem there.
