    18650 batteries will not charge ????

    Bad charger. Took a cell phone charger with 5V output, placed a diode in series then soldered it to the gutted bad charger. Charged the batteries for 4 hours. Worked like a charm. Laser is blindingly bright. Woo-Hoo !!

    18650 batteries will not charge ????

    Understood. I have several laptop batteries that may have cells that are still ok. Planned to re-cycle them but may just open them and see what's inside. Any dangers with charging them in my 18650 charger?

    1 ohm resistors....

    I keep seeing people recommend a 1 ohm resistor to measure current. Good idea to get you in the ball park but the tolerances of most resistors is 5 percent. If it's off enough you can fry your diode. I recommend you set your DMM on the lowest resistance setting, shorting the leads, note the...
