Allright, well i need a led like the one that is in virtually every e-cig charger. I just spent some time googling and no luck.

Two leads

Red and Green

Green indicates charged

Red indicates Charging

Color determined by low or high impedence indicated by charge output circuit

Yada Yada Yada

Thanks in advance for proving my ignorance of google

There are two types of two color LED that I know of:
1. Red/green depending on voltage polarity, 2 leads. AC will light both alternatly to show yellow
2. Three lead LED, one lead for green and one for red.

Not sure that is what you are looking for.

Two lead, dual color. Led stays green while charge chip does precoditioning checks on battery. Turns to red after the preconditioning phase ends. Turns to green when battery reaches finish charge voltage.

charging lights work. there really is no reason to initially charge a battery for 8 hours. The chips in the charger shut down charge after the battery reaches charge voltage. Then you end up with a extremely extremely slow trickles charge or none at all, and leaving it on after the status indicates - is bad. These batteries have no memory effect so their is no benefit to overcharge them for 8 hours. And for the newb video to say that the charge lights don't work is unsafe to say. The led status indicator is tied directly to the charging system itself. When the system is in charge mode the charge output circuit (not the batt charge output) pulls low lighting the red led. When the charge of the battery is complete the voltage to the led changes and lights up the green led. At this time both red and green are illuminated but the eye only sees green. To say the led doesn't work is synonomous with saying the charger doesn't work. Timing a charge is impossible because it varies between charges. Sometimes the battery is over depleted (somehow just inching over that low voltage shutoff) and enters usually a 43ma or so preconditioning charge. That means it has to trickle charge up to a predetermined level before starting normal charge. Eh just my rant
