Lamp good, charger and batteries questionable

Lamp:
makes a good impression and is supplied with the Ultrafire batteries also very bright. Buyer please also pay attention to which model it is. There are single-mode (= on / off) and three-mode lamps (one (high) / on (low) / strobe). Have the single-mode version.

Charger and batteries:
Very cheap processed. Euro plug adapter is supplied, however, is all very shaky.
Have the batteries burn in the lamp can be greatly eased hatte- which incidentally took less than 30 minutes to the luminosity. After insertion into the charger now nothing happens, the batteries are no longer charged. Suspect the protection circuit has been triggered, why not let the batteries now reset. Or the batteries have no protection circuit, although indicated on the envelope, and are fully discharged and no longer be used with it.
No longer trust the equipment and the batteries in any case. Will all my batteries of this type dispose of along with the charger and use "normal" AAs with the lamp. Anyone who thinks that this is an exaggeration, I encourage to again detail to employ with the risks associated with LiIon battery.
