The Spiderbot Battery is a compact, rectangular power unit designed with a pixel-art isometric aesthetic, featuring a metallic casing with visible seams and a slightly weathered texture to indicate industrial use. It has a prominent status LED on one end, glowing in a vibrant green when fully charged, transitioning to red as power depletes. The battery's surface includes subtle engraved markings denoting its power capacity and manufacturer, aligning with Factorio's detailed yet functional design language.
