No they aren't at all. The replacement battery I just ordered for my originally $500 Nexus 6p was $14. Batteries will definitely get cheaper although what might not get cheaper very soon is one especially built for an old LEAF. We may have to wait until small quantity prices drop far enough that third parties can rework LEAF packs affordably.
I have the equipment to test small phone and camera lithium cells. I've tested dozens. I can absolutely guarantee you that none of these cheap ones are remotely as good as original. They come anywhere from DOA, to about 3/4 original capacity (at best), usually ~50-60%, and generally a much shorter life-span. IOW, they are mostly crap, but cheap crap.
I just bought one for $28. I hope my 'expensive' replacement is good, but if not I'll return it.
