Help!
PZ single cell charger mods

I'm trying to get them to run off a 6 V power supply but the negative lead on the red LED runs from one of the 4 AA batterys from the power supply I'm trying to figure out what to do with it? help appreciated (or links to threads)

F&T,
From what I understand the last cell is only used to fire the LED. If that is so the cell will last for years. You could always knock down your 6V. supply to about 4.5V. After I modified my PK charger to reduce the charge current to 80mA the AA's seem to last forever.
Good luck.

P.S. I remember your pictures of your Vapor inspired me to re-cover mine....Thanks.

I got tired of looking at my hugh pile of these stupid chargers so instead of wiring one to be usefull I decided to hotglue/tape 4 of them together and run em of D sized cells

in other words...... a poor mans 4 play charger

Another method for long lasting power is the 1.5V cells of lantern battery from Wal-Mart for about $3.50. They are about double size of "D" cells and soldered together.
