Automatic charging defective

In itself, this HKP is exactly what I was looking for: She has indeed a long breath, easy and glued excellently.
As far as I can judge after a day use. The unit is now just defective and returns:
Despite charged (charging indicator light green) the gun refused red "Invite me!" brilliant service. Placed on the charging station, it flashes a maximum of a few seconds: Battery is full ... but the gun does not start the Aufheitvorgang want to load. No overtemperature, no overcharging, nothing: total objection of a device, on that I want to leave like that should thanks LiION battery be always ready for use but also ... in the hobby "not rely" on the tool very annoying ...

I have to go confess honestly ... the green Bosch appliances really wither now to Qualitätskrepierern!
I am very disappointed by this because it is already the second Bosch green battery unit, which adopted quasi after the first use. (An IXO behaved well.)

With my blue devices I've never had these problems. But just the company logo emblazoned on the green "cheap goods", the so really is not so cheap and naturally awakens the desire of "good" high-class workmanship:
Who wants to have a lot of good from my money, should you please also place a high value on good quality!
It seems to me as if in the green equipment quality control is passed on to the customers ?!
