Postulating that there really was a working battery, (and I think it's safe to assume so), most of the articles I 've read say it was probably used as an electro-plating tool. Building a light bulb, including machining a hard metal, drawing a vacuum , etc. is a lot bigger step than putting vinegar and bronze in a jar and sealing it with pitch.
Besides, if there were a light bulb, why wasn't it ever recorded by anyone like Herodotus? And where are the wires that were used to transfer the electricity from a battery to a bulb? And why, if a light bulb was found, why weren't there wires and batteries found with it?
"...there is also a hieroglyph of an Egyptian lightbulb..."
Where? Share. Give us a link!
baghdad battery
This is the one where they recreated the baghdad battery.

Ancient Egyptian Pyramid interiors and tomb chambers are dark places. During construction of Ancient Egyptian Pyramids and tombs a source of light was needed so workers could see into the dark interiors. Current archeological theory states crude mirrors or oil lamps were used to illuminate Ancient Egyptian tomb chambers during construction
Ancient Egyptian tombs do not have accumulated soot on their roofs you’d expect if torches were used during construction. Some have suggested oil lamps with salt added to the oil kept the lamps from discharging soot. A more likely explanation of how the Ancient Egyptians lighted dark tomb chambers is a light source which has been lost to history.

thats bunk as well
none of the jars found that are called the naghdad batteries by some had electrodes postive and negative external to the area which was believed to contain fruit juice
bit like having a battery surrounded by tape
you couldn't use it as a battery as there was no way for the electricty to get outside the Jar
The artifacts consist of ~130mm (~5 inch) tall terracotta jars (with a one and a half inch mouth) containing a copper cylinder made of a rolled-up copper sheet, which houses a single iron rod. At the top, the iron rod is isolated from the copper by asphalt plugs or stoppers, and both rod and cylinder fit snugly inside the opening of the jar which bulges outward towards the middle (reverse hourglass shape). The copper cylinder is not watertight, so when the jar was filled with a liquid, this would surround the iron rod as well. The artifact had been exposed to the weather and had suffered corrosion, although mild given the presence of an electrochemical couple. This has led some scholars to believe lemon juice, grape juice, or vinegar was used as an acidic agent to jumpstart the electrochemical reaction with the two metals.

Well, no one has yet explained how the Egyptians did all the underground tomb paintings, since it is very dark down there. Oh sure, some will be quick to respond with, "they used torches", etc. Except - and this is a very big except - that torches would have left soot on the ceilings - and there is no soot there
One of the metals would be the negative and the other metal would be the positive. You could simply tap the metals from the top, where they stick out of the jar.
