So when I (expensive) batteries already buy good, it does not make sense to put in a battery charger, which is not even really know when the batteries are full, .. let alone detect defective batteries, shows me the charging status, different battery types and capacities can simultaneously upload, really full loads, etc., etc. The consequences can then be shortened battery life and lower capacity.
I accepted the offer Charger + 8 Batteries Ansmann in 2400, on the one hand because of the price advantage, partly because I suspected that my previous batteries are already damaged by cheap chargers .. and lo and behold - they are there. A battery has been identified as "defective", two others were discharged and recharged within 20 minutes (therefore probably have no more Kapaztät).
To Bediehnen is very simple: clean, finished. There is exactly one button (unloading) the well does just that by pressing. So you can never do anything wrong, neither to use nor in how to loads it (there are indeed recognized: types of batteries, different capacities, defects, battery, how full that is, ..).
From me, then no deduction
