The Spiderbot Battery is a compact, rectangular power source 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 small 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 capacity and manufacturer, aligning with Factorio's utilitarian design philosophy.
