Have the clipper now 3 weeks. Use it 2 times a week for my beard and am very satisfied! Loaded once and since then no more. Battery is still as on the first day. It write some, this is weak here the battery. These people have still not understood as Li-ion batteries function Renal! One example, has written: charged all night and weak after 2 uses battery. Clear !! Man must not load so long as such batteries. It is also on the instructions: Load 3 hours ... not 10! Again the explanation of Li-ion batteries: Load 3 hours, then use up battery is empty, then load 3 hours etc 4 or 5 times. Then the battery for a lifetime is usable! for the full / discharges can load as you want it.
