Banjo Music. courtesy of Banjo HangOut -- Civil War Medley -- Batteries are stone age technology & they certainly do not represent “clean energy”, depending on their electrodes, they may be hazardous waste.

FYI/for a brief period in the nineties EverReady claimed to recycle dry-cell batteries. It didn’t last too long because only the metal cases were. Automobile batteries on the other hand have been recycled except for the plastic cases.

They are only permanent in the sense that many of the materials used in their construction are permanent ie stainless steel. The killer for any battery is “charging cycles”, that is the reason we have 48-month devices.
