A battery that drains as time ticks away.

Battery Timer shows a vertical battery gauge that drains from full to empty as the countdown progresses. Colour-coded segments shift from green through yellow and orange to red, and the charge percentage is displayed right on the battery. Because the metaphor is instantly recognisable, students and audiences can tell at a glance how much time is left without reading numbers.
Ten stacked segments drain one by one for a satisfying visual effect.
Green above 50 %, yellow above 25 %, orange above 10 %, red below 10 %.
The remaining segments pulse when the battery drops below 10 %.
