Charger issue.

Picked up one of these:
AG-126 Lithium Ion Battery Charger

For my Chuck.

Issue is that the charger itself doesn't have positive and negative polarity points.

If I put the brand new batteries in one way it shows green, flip them around and it shows red.

I don't want to burn these guys out by over charging them. So what do I do to figure out which is which?

I'm still waiting on my Chuck to go through the batteries by the way - I guess the ultimate solution is to wait for the Chuck and use a battery up, then whichever way turns red is the proper polarity for the battery to charge?

The neg end is on the slide the pos is the stationary end. If you look close there is a picture ingraved in the plastic where the battery goes.

The negative is gonna be on the part that moves and the positive on the fixed side.
