The documentation with the Raw is abysmal...no...that's not it. It's absent! There is no documentation for the light or the charger.
So...I'll give you a heads up.
Inside the ziplock bag with the charger was a tiny envelop stapled shut. On it was printed "Clear Watch Crystal". I almost didn't open it, as I figured it was a spare lens. But curiosity got me and I opened it. Inside was not a watch crystal, but two tiny toroidal magnets. I went to the Orb website to see if they were mentioned. They weren't, but they're identical to the magnets used in the Orb light, so I figured they were included by mistake.
I promptly began playing with them and soon lost them!
Last night I went to charge the RCR2 battery. I put it in the Nano charger...and it was 1/4 inch too short!
<LIGHTBULB OVER HEAD> So THAT'S what those little magnets were for...a spacer!
Well...after scrounging in my toolbox for a few minutes, I found some small washers that will fill the space, and that works. (still hope I find what I did with the magnets)
Next, I plugged the charger in, and the LED lit red. I had no idea whether the LED would extinguish when charged, change colors, or if red actually meant that the battery had a full charge.
As it turns out, the LED does change to green when charged.
To the Orb folks: How about spending 10 minutes writing some simple documentation for the charger, beginning with "DON'T THROW OUT THOSE TWO MAGNETS that we didn't bother to tell you what use they had."
