John Safran - Not the Sunscreen Song

NiMH has been common in consumer batteries for around 15 years (in my experience, although Wikipedia shows the chemistry is way older) but you can still buy the other chemistry (NiCd), and there may be newer lithium rechargables but I haven’t seen them in standard sizes (AA etc)

Eneloops set the standard for good quality NiMH batteries for a while, but IKEA Ladda batteries are also NiMH, and probably plenty of others now

Because rechargable batteries before NiMH sucked for many use cases - they were good for the Gameboy as you charged and used them straight away at high draw, but try using one in a low power device like a remote or wall clock and you’ll find it is dead in a week despite minimal actual usage

This is somewhat outdated, developers can now opt in to reproducable builds using their own keys
