As a flashlight and batteries arrived, I naturally immediately inserted a battery. The lamp remained dark. Unfortunately, I was on the flashlight not detect polarity and so I turned to the battery. The lamp remained dark. A clear case of "battery low". So the charger into the wall socket. Both LEDs under the charging compartments glowed green. Inserted the batteries and the LEDs lit still green. "Strange really," I thought. "Well, maybe the LEDs go out so, when the batteries are full."
One day later, the LEDs lit are still green. I thought to myself, but that at least some juice would have to be in the batteries now. So battery in the torch and ... the lamp remained dark. When I was about to reverse the polarity of the battery, I noticed a small seam on the side of the battery. When I looked at it more closely to me, I found that the batteries are verschweist with a very thin but tough, crystal clear film.
So gepult batteries from the film, purely in the charging cradle and the LED changed from green to red. The next morning, the LEDs were then green. Battery in the Rasch lamp - to light!
Well, do that! Especially when the insulating film is removed.
