Charger Digital Charger 4S without batteries

Short summary for readers with little time:
***********************************
Good charger which Li-ion and Ni-MH / Ni-CD batteries can with up to 1A load quickly. Batteries are not hot, but are also loaded with only about 85% of capacity. Schön is the illuminated display, the function for capacitance measurement, and actually the beeps, but which are not switched off and can be very annoying.
Looking for a good and safe charger which both Li-ion and Ni-MH / Ni-CD to load batteries, then you can not go wrong here.

Detailed report:
***************

Style:
*******
The Design of Digital Charger 4S is quite clunky, rectangular and not particularly elegant. It is operated via a single button on the top right of the charger. In the upper part there is the display, which is deposited with a blue backlight. This can be seen, the values ​​even in low light conditions or even at night. Downstairs are rubber feet to slip to avoid slippery surfaces.

Scope of supply:

- Charger
- Power Supply
- Connector for connection in car

The plug for charging in the car is not bad, especially when making the children resulting from extensive driving the batteries limp, making it the family peace rescued.
There is no separately printed manual. What you should know is on the packaging, but only in English and also quite scarce. When BC 700 is for doing a thick notebook.

Operation:
**********
The instructions for this is available in English on the packaging (not throw).

For those who can not speak English here receive the translation:

Instructions for the charging process:
A: If the plug is not plugged into the socket, then the display will show nothing.
B: When the plug is inserted in the socket, but no batteries are inserted, all the values ​​are first shown on the display and then zero. In the middle of the set charging voltage and 0.50A CHG for charging (Charging) is displayed.
C: When you insert batteries, can (Li-ion) and Ni-MH / Ni-CD batteries automatically distinguish between the charger Li-Ion. It shows on the display the current voltage and the charged capacity. In addition, the battery icon shows that run through dots to the right, that the charging process has started. By short pressing the button, the charge current can be changed (0.5A or 1A).
D: When the charging process is complete a signal tone sounds (two times per three loud beeps, depending on battery)

Instructions for testing the capacity:
A: Keep the button pressed for a longer period. The display changes from CHG to CAP.
B: When charging is completed, the alarm sounds. Thereafter, the voltage readout and the charge indicator runs backwards. The capacity indicator starts counting the determined during the discharge capacity.
C: If the minimum allowable voltage of 2.7 V at 0.9 V Li-ion and Ni-MH reached at / Ni-CD, then the discharge process is terminated and an audible alarm sounds. The displayed value corresponds to the capacity of the true capacity. Then the charging process, the end is signaled by a buzzer starts.

When you have familiarized yourself with the instruction manual, operation via a button is quite simple. Disadvantage for all bays always applies the same setting. I particularly like the illuminated display, where you can read the values ​​well. Equally important are the non-defeatable beeps, especially if you use the unit overnight. Otherwise, the signal tones, useful particularly for the completion of the charging process. Since you do not need to constantly look at the screen. The batteries are due to the max. Charging strength of 1A load afloat. Unfortunately, there are only two selectable charging currents with 0.5 and 1A. Whether my AAA or very old batteries by keeping the longer time I do not know. So far, however, it seems to them not to harm. Ever is very surprising that despite the high battery charge current to warm little. This is probably because that the delta voltage U control strikes quite early and prefer a little earlier charging terminates the AAku vollzupressen than up to the neck. Opposite my BC-700 batteries are charged only about 82% of capacity. Maybe you would have here are not to renounce an additional temperature monitoring of bays. Then one could have fully exploit the capacity of the batteries.

Pros and cons:
****************
Benefits:
- Possible with 1000 mA high charging current and short charging times
- In addition to Ni-MH / Ni-Cd batteries and the charging of Li-ion batteries is possible
- Backlit display
- Possibility of Kapazuitätsanlayse
- Batteries and equipment are barely warm
- Beeps
- Reverse polarity protection (zero indicator)
- No problem in accidental insertion of alkaline batteries. Batteries (few seconds) after a short time as a full. A heating or overload does not occur.
- Additional cable for use in vehicles
- Fanless

Disadvantages
- No way to adjust individual shafts, always all four together
- No charge current is below 500mA (possibly useful for old batteries and AAA sizes)
- Apparently no temperature monitoring
- No refresh function
- Quite large
- Not be switched off beeps
- No separate operating instructions, instructions on box and only in English

Conclusion:
*******
Good charger which Li-ion and Ni-MH / Ni-CD batteries can with up to 1A load quickly. Batteries are not hot, but are also loaded with only about 85% of capacity. Schön is the illuminated display, the function for capacitance measurement, and actually the beeps, but which are not switched off and can be very annoying.
Looking for a good and safe charger which both Li-ion and Ni-MH / Ni-CD to load batteries, then you can not go wrong here. Should there be only Ni-MH / Ni-Cd batteries with really full charge and full control of each slot, then I would rather recommend the black Technoline BC 700 Battery Charger.
