Well, rechargeable batteries are... rechargeable...
Cheap 16340 + Charger = Dealextreme
Best 16340s = AW IMR 16340 (lighthound.com)

You've just been spoon fed, yw.

3 days doing what?

If its empty after 3 days of not turning the laser on something is wrong, but you'll usually run for less than an hour on such a cell with a 200 mW green, perhaps you can run a ~200 mW red for 3 hours straight.
