I won't claim more familiarity, but...
- How frequent/difficult is required maintenance? Recall that old lead-acid batteries often needed distilled water added to their cells.
- Does it need access to air - either supplied to it, or to vent gasses? That introduces a whole host of issues, even if it's not venting (say) hydrogen gas.
- How much does performance degrade when its only cycled through part of its charge/discharge range? Recall the NiCad batteries of yesteryear.
- What are its waste, OSHA, HAZMAT, and other environmental & safety issues? Those apply all the way from the raw materials mines to the final disposal. Which includes accident scenarios - fire / flood / whatever in a facility with many batteries (or parts thereof), one-off car crashes, and things more interesting. "Disposal" includes cases such as "abandoned in a pole barn".
(BTW - kudos for specifying "How available are ...", which covers a far longer list of real-world supply issues than "What is the (current) price of".)
