Or you stand at night with flashlight in the dark ...

"In some battery types wid charging not completed when the battery is fully charged, or are not even charged.

The regeneration function takes up to two days and brings virtually nothing. "

Or the batteries are shown as charged and are not.

Or are you standing in the dark at night with flashlight and swapping the battery and the battery is empty even though he just comes out of the charger. LoL.

This happens so every fourth charging. Will send the part as defective back.
He has the Aldi and Lidl batteries simply and easily upload completed.

Update:
That with the refresh is me rather unimportant.
Of course I have repeatedly stood in the dark.
I have a battery in the lamp and take a fully charged spare battery with.
I'm pure .... and he is freshly charged while empty.
And I stand with my bike in the dark without light.
Then I have got used to reload all freshly charged batteries in my old charger.
Lo and behold, about every 4th allegedly freshly charged battery was actually empty. Always, however, another one of my more than 30 batteries. Then have the "defective" batteries with tape marks and after a while I soon had 15 batteries with tape that but then reload the device discussed here could be the next attempt.
This has really served as a test ...

Update 2:
Why feel only 0 of 2 customers here than helpful, I do not understand now.
I'm not the only one who reported the same defect.
And if the charging defect not continuously and not always occurs, it may take a long time, until he noticed the other customers at all.
If then after half a year or so the failure of the device is detected, the jubilation reviews are not corrected. Bang!

I auche only thought that would be a bad battery in. Only I can easily charge with my big supermarket loader.

Also, I do not assert that all devices delivered have this defect. So please also like to mark a "helpful".
