Supposedly the Egyptians did know how to make a simple battery. Mythbusters reproduced the battery and it produced around 4 volts. It only takes 1.5 volts to produce hydrogen gas from water via electrolysis. It’s technically within the scientific capability of the Egyptians to do this, although I don’t think it likely.
Wow TIL, the ancient Egyptians knew how to harness hydrogen gas! /s

It was not Egyptian and almost certainly not a battery.
Milo Rossi has covered this in detail in a very good video.

He also has a follow-up to that video with an expert on the subject, an actual archaeologist who has studied the so-called battery.

It’s capable of being used as a battery. Doesn’t mean it was.
