I have a number of AA rechargeable batteries sitting around the house that need to be fully drained in hopes of getting a good charge once again.Anyway,3 weeks ago I put 3 of the batteries into a Task Force LED flashlight I got at Home Depot and turned it on.The light has clearly dimmed but at night before I go to bed the glow can be clearly seen! I guess I need a "faster drainer" or I'll never have good luck with my stupid battery hog digital camera.
