Colorful Battery Icon

This illustration shows a battery, likely used as an icon to indicate power levels. Inside its clear casing, a colorful gradient fills about two-thirds of the volume, transitioning smoothly from a warm red at the top to a bright yellow in the middle, and then down to a refreshing green towards the bottom. The metallic silver ends, especially the raised positive terminal, give it a polished and functional look, perfect for digital interfaces.
