A basic chemical battery is most usually a small terracotta jar full of date vinegar, and a plug pierced with one copper rod and one iron rod. Placing the plug in the jar produces around a volt of electricity for four hours! Such a battery weighs about two pounds.
With the help of Nectors to make more strongly acidic substances, it's possible to get the jars up to nine volts for ten hours - but those batteries weigh about twenty-five pounds apiece.
