Meanwhile, I'm gone over almost everywhere to use batteries and recharge so that you do not ruin this (with the CM420). The baby monitor made the beginning, it is also here that one should just let the included NiMH batteries times the 8h on the network. The then run veeery slowly fully (to low power = crystal formation) and if they are a bit too crowded which is allegedly not so bad. Aha. Well, at least the first 10x charging folds yes.
When Beard Trimmer here the same approach is recommended to schwammigste way. The result: The batteries contained are strongly after and I operate the trimmer virtually every 2nd-3rd times the cord.
Now you might think so, but because only 2x AA NiMH are guaranteed inside. A flap in order to remove them there were unfortunately not. But no screw holes! This thing is completely clipped, no way aufzukriegen it without damage. The trimmer is thus to repair or Wegschmeißware and I find that shit, because with the (lack of) charging technology is clear that the batteries contained come quickly.
Next time I'll be careful. Here goes, apart from the battery, to the thing probably nothing broken. I wish I had bought a beard trimmer with battery operation. For those who no batteries (most were sure the Eneloops) used in the household, the handle to a costly model is likely to be the cheaper option with Ladeleektronik long run.
