They had crude but working battery cells in egypt.
Those images which look like light bulbs are actually something else to do with a representation of a plant connected to a ‘god’ - I don’t recall which of what as lack adequate AM coffee.
Those ‘battery cells’ may also actually be something else since modern Egyptology is in existential turmoil at present. Nothing long claimed as true is correct, since most everything is based on “dynasty dating” (with some carbon dating thrown in - but modern bio-thermoluminescence dating is forbidden for all practical purposes).
The “dynasty dating” is based on a 19-20th century known forgery called the Kings List. The List says King X lived before King Y, but King Y at times used the same name as King X; and no one knows who all the kings are or even who the first kings were.
However, Old Kingdom Egypt (OKE) had excellent surgeons using technics not rediscovered until the 19-20th Centuries AD.
