And some have largely disappeared from use, like the NiCd battery, supplanted by the NiMH. Apparently they’re only allowed as replacement in the EU. Not arguing against your point about variety but just pointing out that survivorship of one doesn’t guarantee another won’t die out. 😊
Lead acid batteries were invented in the 1800s and we still use those. Variety in technology is a good thing.
