Battery exchange has been done for over 30 years in commercial and industrial EV's.
Golf and Western make a aircraft ramp test vehicle that have two battery packs that are 15 feet long. They slide out below the deck onto a carrier. These battery packs are normally made by this company as a standby to a standby generator in communications centers. I was working with the GW technicians on a defense contract and ask them for info on these batteries. I call the company and they said factory cost of one battery is $125,000.00. The plates are gold and titanium back when gold was under $400.00 a oz. They can drive a equipment van on the aircraft ramp for 400 miles. In Germany they have street buses that have battery packs in nylon rack panels, that also slides in from the side of the hinge compartments below the passenger deck. These plug into a center plug in buss way. If a battery pack goes into fault, it automatic ejects from the plug in buss bar leaving the other packs to drive the EV. When the bus gets back to the bus depot, they can either slid out this and replace it with another. Or the tech can look at the cell itself which may have which can eject itself from a buss bar located in the bottom of the rack panel. They can just pull out that cell and plug in another one. Again this was not cost effected for my EV, They quoted me $39,000.00 for just enough battery cells to go 20 miles.

I'd never lease a battery. Property that is rent/leased has no value to the leasor and is hardly every treated with respect that an owner would use. Take a look at any rental property and see plenty of examples of abuse. It succumbs to the worse ailments of human behavior.

Really, home charging is the best idea of all. I think the swap is mostly eyewash for people used to having to go out for their fuel. That and for long voyages. There are some advantages to leasing packs - put their care and feeding more in the hands of the manufacturer. I can imagine "tow trucks" like a roll back, with a battery swapper in the bed. You call AAA and they have the tow truck pick up a correct pack and bring it to you for swapping.
