510 Charger Question

[CloudCuckooMan]

I was under the impression that my 510 charger was just supposed to go from red to green when it's done charging. But mine turns yellow alot. And sometimes it flickers between yellow and green. I couldn't find anything about this searching online. Does yellow mean almost done or something? I even bought a new charger and it does the same thing. I'm getting an ego on Monday so I won't have to even worry about it anymore but I was just curious.

I found this thread, http://www.e-cigarette-forum.com/forum/battery-issues/163729-510-charger-yellow-light.html , but they didn't come to any conclusions. I think it's a fault light and would recommend cleaning battery and charger contacts. I get a yellow on my Trustfire chargers every now and then. Always just bad contact with the batteries though I'm sure there's a long list of things that can cause it.
