Gentlemens: OK, this has NOTHING without a stretch in imagination to do with bicycles so I apologize in advance.
A couple of years ago I received one of those wind it up LED flashlights for a gift. It worked so I merely put it on a shelf awaiting a hurricane or other power outage which never came. I went to use it yesterday as I needed a little focused light to repair another flashlight and it was kaput, dead, failed to function. The light did come on when I turned the crank but as soon as the cranking stopped so did the light.
Today I took it apart figuring there was probably a little rechargeable AA battery in there. There isn't, there are a LOT of gears that take a bit of figuring to get back together again which came apart as I couldn't find a AA or AAA battery and took it ALL apart.
There was a LIR2032 dime sized battery normally used for powering garage door openers and the like. It was epoxied, plastic wrapped and soldered in place. Not to be dismayed and since I had a fillet knife on my workbench and other various small tools I took it out and went to the utility drawer where I had a pack of CR 2032 batteries. They look identical but the LIR2032 claimed in very fine writing to have 3.6 volts while the CR 2032 claimed only 3. A meter on the CR2032 indicated this particularly one had 3.7 and since it's Labor Day and since everything is probably closed and since I already had this battery in my hand and I don't like the damn flashlight much anyway, I put it in and used various pieces of cardboard, electrical tape and luck I got everything back together again and lo and behold, it works. The light is fairly bright but gets brighter when the crank is turned so I know everything else is working too.
My question is: Is the CR2032 rechargeable? Is the LIR2032 rechargeable? The text on the LIR2032 reads Lithium ion while the CR2032 merely reads Lithium. There is not enough room to replace the 2032 series with a AAA or similar rechargeable battery and I found a blister pack of really nice maglite knockoffs at the Home Depot the other day for less than twenty bucks and since I'm kind of a flashlight freak anyway I'll go back and buy it when my wife isn't with me. (she thinks I have enough flashlights, a man cannot have enough)
Fortunately I have another, better quality I think, one of these in my workshop in case of emergency. I also have a few regular flashlights in there so I can find it. I'll probably wind up taking it apart to see what kind of battery is in it.
