The umpteenth flashlight was completely corroded out by a battery that leaked despite the fact that it was delivering power. It almost wrecked a nice cabinet along with it. So, I just got a flashlight with crank from Costco. Duracell KP028, two for $15, even has a radio with weather band in there. Now I am curious: Does anyone know what kind of batteries are in there? Maybe even a super-cap?


IMO,Duracell batteries are prone to leaking. If they are used in your crank flashlight,then that will fail,too.
Get a flashlight that uses lithium cells.


Hmm. They also had a four-pack of others but I figured a brand name might be better. Plus the radio feature is nice in case the really big shaker comes.


Google didn't lead to any hints and according to the Duracell site they don't even make them (!). Then again their site isn't very good, lots of "The system cannot find the path specified."

I am not a fan of LEDs, they just aren't as bright as regular flashlight bulbs.


The 1W and 3W Luxeon LED lights are pretty good.


But this thing is pretty good. One minute of cranking and it lights long enough to find stuff, even keeps its charge. Ok, they say 30 minutes but it gets dim after 5-10 minutes. Good enough for me, if the battery holds up over the long run.



IF.


Well, great, here you just blotted out my optimism ... Oh well, let's hope it lasts. We also have a humongous $10 flashlight with a lead-acid gel cell. It was said not to last but surprisingly it has now lasted three years. We use it every day to clean up after the dogs when they do their late night potty. You can light up the road signs clear across the valley with that one.
