How long will this 1.5v AA battery power 1 LED on a solar walkway light?
Due to connection difficulties...i have decided to use a regular AA 1.5v battery to power this solar walkway light. I have disconnected the electrical wire so the "solaring" will not be in use. With this nonrechargeable battery taking the old recharagable battery's place, I was wondering how many hours can this 1.5v battery power 1 led.

At a low discharge rate (the LED probably draws about 20ma) the AA alkaline battery should have about 2 AH available or approximately 100 hours. So if it is on only at night, or for about 12 hours it should last for 8.3 days.
