Re: It's not a battery
'Battery' comes from the Latin 'the act of beating', and so organised groups of artillery became known as batteries. This usage was extended to other arrays of similar things, so a group of power cells became known as a battery. In fact today we often use 'battery' for mere single cells, as 'AA' often are - by contrast, square 9V 'PP3's are batteries of lower voltage cells. This power station is a battery of valves and turbines.
And should you be standing in the wrong place at the wrong time, it would certainly batter you, like an egg in a food blender!
