- criddell 2y agoI think you are moving the goalposts. The batteries I linked to are consumer standard lithium chemistry batteries that people can buy off-the-shelf in drug stores and be used in smoke detectors and kitchen scales.
- _yb2s 2y agoNo we’re talking about rechargeable batteries here… disposable lithium are too expensive and wasteful for frequently used high drain devices. I love them for emergency equipment like spot trackers and emergency strobe lights
- mitthrowaway2 2y agoWhen I said lithium-ion I was indeed referring to secondary (rechargeable) batteries. Apologies for not making that clear. AA and AAA Nickel-metal-hydride rechargeable batteries exist, but it doesn't seem anyone ever made a li-ion equivalent.
- ssl-3 2y agoLithium rechargeable AA cells do exist, and they're perhaps even more mind-bogglingly complex than you'd ever imagine: https://paleblueearth.com/products/pale-blue-lithium-rechargeable-aa-batteries https://paleblueearth.com/products/pale-blue-lithium-recharg... In order for them to function: They've each got charge circuitry, buck converter circuitry (to get down from 5v to ~3.7v lithium voltage for charging, and from ~3.7v lithium voltage down to 1.5v to be compatible with end-user devices), and each one includes its own USB C port.
- samatman 2y agoThe comment you're replying to specifically said lithium-ion battery. What you linked to is a lithium metal battery. They aren't the same thing.
