Fast loading - Battery diagnosis benign design fit

Service:
As a technician, I do not read instructions. The device has very fast an overview of the status of each slot on a printed scheme as de lights are on or can blink.
Also, a "non-technsich-savvy" person came quickly clear the operation.

Features:
Battery discharged, unloaded, checked and trickle charge are great.
2700 mAh "expensive" batteries were charged after approximately 4 hours.
2000 mAh "cheap" batteries were loaded 4h later also.

Knowingly defective batteries (deliberately inserted) after max. 20 sec. recognized.

Also one of 4 entirely new V **** - Batteries are diagnosed as faulty, measured it with 0.8V and no measurable current more, though "ready to use" - also the dealer confirmed this and exchanged.

Clean !! emotionally !! after 10 charges keep better batteries also getting longer.

The machine is not overly warm.
If you listen carefully GANZ (max. 10 cm distance) you can hear a very slight hum of the (controller?) Depending on which mode the charging Chat has (loading / unloading).

Design and construction:
The device is provided with roundings and is slightly curved upwards. The housing is made of solid, yet lightweight plastic with gray / blue colors.
It stands firmly on his feet and not Wacket.
On our sideboard it has done well, no globiger box with flap, which disturbs the overall picture.

Conclusion:

Gelunges device with simple operation and efficient use.
The design also ensures a company is reputation.

It replaced my previous "Charger" of C ******.

Improvement:
Possibly even improve Anzigen why the battery is defective (double flashing or so)

Suggestions
- A high-end device with RS232 / USB interface for reading out the charge - characteristics or battery health. Such a device would then get a permanent place on my desk.
