Well, obviously, it's a flashlight, but I couldn't find a thing about it on the internet. It doesn't seem to open in any way, and there's a switch with two positions; "on" and "recharge." I experimented with charging by connecting my power supply to the two metal terminals. It took 1-2 mA at 4V, but a red charging light didn't come on until it reached 7V, so I assume it contains two lithium cells. I've had it charging for 2 days now, but it won't take more than about 7 mA. The red charging LED illuminates, so I assume I have the polarity correct. No sign of overheating, but I assume the cells have been dead for so long that they don't take much of a charge. I have brought back other cells. It looks like some sort of small light that clips into a charger. Diamar seems to be a ski equipment manufacturer, but there's no mention of flashlights on their website.
