Battreminder — Reminds you when your laptop battery is fully charged!

There's by default a reminder, for almost all laptops, which lets you know when the battery is low. But, how to know when the battery is fully charged? This light-weight minimal browser extension will let you know the battery level and will remind you with a sound notification when the battery is fully charged!
