getting more energy out of AA and AAA batteries

[norman6538]

Looks good but....
But how long will they light with no mags???

or how many milliamps do the  leds require
and how many milliamps do the batteries contain?

Its all about measurement and comaprrison new vs old.

Hi Norman: before I took that headlight apart to use the 5 leds in my experiment, I had accidently left it on a few times, at which time it had duracell batteries in it.

And I know it wasnt more than two or three days when I went to use it again that it was completely dead. Have you ever left a flashlight on by accident? then you know what I

mean. But you are correct I am not doing the experiment correctly. I just thought  13 months of continous light was pretty decent out put. I never shut it off!!!!

I have never had a flashlight do that before

@ stiplant: I will try to do a drawing for you, the only batteries I have tried this on, are the ones in the picture. as far as lead acid batteries go I think they are to wide for

the magnetic attraction, but I suppose it would be worth a try

What a feeble attempt. I use a big holding magnet and a 12 V battery. And I am driving my electric bike since two months with it. No recharging of course.

I do not divulge more details, because I am planning to go into business with that discovery.

One detail for free: a steel sheet is enough, no heavy steel bar to be lugged along.

If you do something, do it right! And who needs a few leds?

Hey conrad, why not stick that magnet up your ass and see if your eyes light up, I bet they would!!!

and then you could make a you-tube video of it for entertainment, I think everyone here would love to see it

what a tool!!
