It is a logo for a dying battery. It is a battery shape but with a line through it stating that it is either low or that it is dying. It has lines going vertical to display how many bars are left that are still charged.
This No Battery icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,900 icons, all in the same style and quality.
