Li-ion Weird phenomenon

pwillard:
With LiPo/li-ion batteries, voltage is a poor indicator of charge as the difference between fully charged and dangerously discharged is rather small.

Yeah, but the LED was supposed to stop after 9-10 hours because of it's 0.3W draw and the battery's 2.96WHr rating.

Have you tried recharging it fully ?

I will when the battery runs out of juice. Whats the matter?
