Main disadvantage is cost. Looking on Amazon, it's $1.61/ea AA lithium vs $0.62/ea akalaline. That's Energizer vs Energizer. Amazon Basics AA alkaline are $0.32/ea. (Unlike alkaline, knock-off lithium aren't much cheaper than Energizer.)
If I had a dollar for every device that I've seen ruined by leaking alkaline cells, I could buy a palletload of lithium cells.
Well how many batteries do you need as long term storage for emergency use? $10 worth?
Everything else use rechargables for a dollar-ish plus charger cost.
I actually can't think of anything besides smoke detectors that I'd use these for, of which my house has 10 or so. Not having to replace those yearly would be worth it. I use Eneloop NiMH or Li-ion rechargeables just about everywhere else.
