The „Charge Manager 2016“ is a quick-charger for perfect maintenance of rechargeable NiCd, NiMH and NiZn batteries type AA/Mignon and AAA/Micro, C/Baby, D/Mono and 9 V block. All charging and care programmes are also available for NiZn batteries of the build AA/Mignon and AAA/Micro. The microcomputer-controlled quick-charging process charges NiMH/NiCd/NiZn batteries to 100%. 100% means up to 115% of the capacity indicated for new rechargeable batteries and less than 100% of the capacity indicated for older ones. For batteries with a capacity of less than 750 mAh, the discharge capacity (D) may not reach 100%; this discharge value, however, must be greater than 80%. Otherwise the battery is defective (preferably test with the „ALV“ („ALIVE“) programme). This charging set does not require a discharge before starting the recharge process. The battery is charged to the currently possible 100% from its current charge condition. The recharging and discharging cycle is microcomputer-controlled independently of the charge status of the battery. Both the available charge currents and the discharge current are selected to fit the practical conditions. The charger has an automatic maintenance charge and energy saving mode. The charger has an automatic battery monitoring system (charge current and charge amount). The automatic battery detection registers if a battery is inserted or removed. No memory effect occurs when charging (charge and discharge current are clocked). This reduces a high internal resistance of the battery and increases its current carrying capacity. The efficiency of the batteries is improved (ratio of the required charge quantity to the capacity that can be delivered).37

7. GENERAL INFORMATION

Rechargeable batteries consist of two electrodes put into an electrolyte; thus, a rechargeable battery is a chemical element. Chemical processes are running inside this element. Since these processes are reversible it is possible to recharge batteries. To charge a rechargeable battery, a so-called charge voltage is required. It must exceed the cell voltage. Moreover, the energy (mAh) supplied for charging must be higher than the one that can be delivered afterwards. This ratio of the energy supplied to the energy drawn is called efficiency. The capacity that can be delivered mainly depends on the discharge current; it is decisive for the condition of the battery. The supplied charge cannot be used as a measure, because a proportion of it will be lost (for example converted into heat). The capacity data given by the manufacturer is the maximum theoretical quantity of current which can be delivered by the battery. That means that for example a battery of 2000 mAh can theoretically deliver a current of 1000 mA (= 1 A) for two hours. This value considerably depends on many factors (condition of the battery, discharge current, temperature, etc.). a) Definition of „C-Rate“ This is a factor (multiplier) delivering the value of the permissible charge or discharge current independently of the battery capacity. The multiplier is the battery capacity. The following applies: Battery capacity (in mAh) x C-Rate = Value (charge/discharge current in mA) Examples with rechargeable batteries at 1000 mAh and 2700 mAh: C-Rate = 1C C-Rate = 2C 1000 mAh x 1 = 1000 mA 1000 mAh x 2 = 2000 mA 2700 mAh x 1 = 2700 mA 2700 mAh x 2 = 5400 mA38 b) Selection of the Suitable Charge and Discharge Current The „Charge Manager 2016“ automatically adjusts the charge current. For NiMH, NiCd batteries, you can also set the charge current manually. There are four charge currents selected according to practical requirements: 500 mA, 1000 mA, 1500 mA and 2000 mA. For NiZn–batteries, the correct charge current is selected automatically. A charge current of 500 mA is recommended for:

• Batteries without information on charge type and a capacity of less than 3000 mAh

• Rechargeable batteries with the print „Standard charge: 12 - 15 hours at xxx mA“ („Stan- dard charge: 12 - 15h at xxx mA“) A charge current of 0.5 C is recommended for:

• Rechargeable batteries with the print „Fast charge: 4 - 5 hours at xxx mA“ („Fast charge:

• Rechargeable batteries with the print „Fast rechargeable“ or „Quick charging possible“ The example batteries from chapter 7. a) would result in the following charge currents: 1000 mAh x 0.5 = 500 mA 2700 mAh x 0.5 = 1350 mA

The „Charge Manager 2016“ does not always offer the precisely fitting charge current. In such cases, the next lower current range is the correct choice. For the 2700 mAh rechargeable battery, this means a charge current of 1000 mA. A charge current of 1 C is recommended for:

The 2700 mAh rechargeable battery is charged at 2,000 mA here. When charging a battery with a charge rate of 0.5 C or 1 C, the battery will heat up noticeably towards the end of the charging process. This is not an error!39 c) Discharge Current In the „Charge Manager 2016“, a discharge current of 150, 300, 450 and 600 mA is available for NiMH- and NiCd-batteries; for NiZn-batteries, 200, 400 or 600 mA can be selected. For 9 V-block batteries, the discharge current is selected automatically. It is at a rated current of 20 mA.

Long-term determination of a battery’s capacity can be used to determine its current condition (capacity loss). The delivered capacity depends strongly on the discharge current: The lower the discharge current the higher the capacity that can be delivered. Since the battery is discharged via resistors, the actual discharge current depends on the current battery voltage. This is, of course, also considered in the capacity calculation (DCAP) of the „Charge Manager 2016“. Normatively, the battery capacity is determined at a discharge current of 0.2 C. For the example batteries, this means: 1000 mAh x 0.2 = 200 mA 2700 mAh x 0.2 = 540 mA The discharge current must be chosen that comes closest to the calculated value. For the example 1000 mAh battery, these are 150 mA, and for the 2700 mAh batteries, a discharge current of 600 mA results.40

8. DISPLAY AND OPERATING ELEMENTS

1 Charge slots S1-S4 for round cell batteries 2 Charging chutes for 9 V block batteries 3 Charge chute cover (removable) 4 Display for: - Input menu - Overview of running programmes - Cell/loading parameters 5 Operating buttons „<“ (left) and „>“ (right) for input / selection „OK“ to confirm

The two operating buttons „<“ and „>“ are designated as selection buttons in the further course of these instructions. Connection (back of the device): 1 Data interface (USB-B socket) 2 Voltage supply connection (12 V/DC, hollow-plug socket, plus pole/+ inner pins, minus pole/-/GND outer pins)41

a) Charge Programmes The „Charge Manager 2016“ provides a total of five programmes for processing the rechargeable batteries:

• Revive („ALV“ = „ALIVE“) b) Maintenance Charge If the rechargeable battery is left in the charger and it is required, the maintenance programme „TRICKLE“ (display „TRI“) is started automatically. c) Energy Saving Mode If all programmes are processed (display „RDY“) and no button was pressed, the device switches into energy saving mode after approx. one minute. The display is also switched off in this. Pressing a button, inserting another cell, possibly removing cells or starting the maintenance charge will lead to leaving of the energy savings mode.

Automatic recognition of deep-discharged 9 V blocks is not included here, since this is contradictory to maximum energy efficiency. If this situation occurs , the device must be activated by „OK“ button. After several seconds of „Auto-Refresh“, the battery is recognised and the programmes are available. d) Memory-Backup This charger has a memory backup; this means that programmes and the accumulated capacity values of batteries are retained for up to one week without power supply. Never change the battery when powered down! The charger no longer assumes the valid data and there would be incorrect values and damage to the new battery! Continuous and programmes is only possible if the installed buffer memory was loaded. For this, the charger must be connected to the voltage supply for at least two hours.42

10. PARAMETER DISPLAY

a) Battery Voltage The voltage of the battery is indicated in the unloaded condition (and can therefore not be measured during operation). b) Charge Condition To give you a general idea of the state of the rechargeable battery this device displays a battery symbol („ “). This symbol only serves to estimate how far the charge or discharge process has progressed. When charging the battery icon fills from the bottom to the top while it empties from top down when discharging. During automatic multi-step charging of NiZn batteries, the bar graph display (battery icon) indicates the progress of the respective charge condition. Conclusions regarding the expected time remaining until the end of the programme are not possible from it. c) Charge/Discharge Current When charging and discharging the current flowing into the battery „I“ is displayed. If no current is flowing (e.g. in the mode „RDY“ („READY“) or „ERR“ („ERROR“), the display shows „I = 0.000A“. d) Time Measurement The display shows the time in hours and minutes („HH:MM“) over which the battery was charged and discharged. The time required for maintenance charge (operating mode „TRI“ = „TRICKLE“) is not considered. e) Fed in and Removed Capacity The capacity (C) charged into the battery, as well as the discharged capacity (D) is stated in milliampere hours (mAh). In programmes with several charge and discharge cycles, only the current values are displayed. Data of the previous cycle are deleted. No calculation, display or addition of the capacity of a maintenance charge („TRICKLE“) are performed.43

First connect the voltage supply. Always connect the low-voltage plug (hollow plug) first to the connection cable of the mains adapter to the DC input socket of the charger. Then the mains adapter must be connected to the corresponding mains socket.

As an alternative to the included mains adapter, the charger can also be supplied with power using a suitable car adapter (not included in the delivery, can be ordered separately), which supplies an output voltage of 12 V/DC and has an output power of 21 W. The display shows the following message for approx. two seconds: During this time, the charging device carries out a self-test and checks for any existing batteries. The charger is now ready for operation. Readiness is displayed now if no batteries are inserted: The displays „1“ to „4“ represent the four round cell battery charging chutes „A“ and „B“ for the two 9 V block battery charging chutes. The alignment on the display corresponds to that of the ´charging chutes of the charger. CM2016 ================ SELFTEST RUNNING

a) Selection of Battery Chemistry After inserting the first battery into chute 1-4, the following display appears: According to the voltage of the inserted battery, NiMH or NiZn mode is suggested. For deep-discharged batteries, the active battery chemistry may have to be changed manually. Select the battery chemistry with the selection buttons and confirm with „OK“. If no button is pushed, the current automatic selection is assumed after about 6 seconds. Always use the correct battery chemistry for the battery inserted. Mixed equipment with NiMH/NiCd and NiZn batteries is not permitted! There is a danger of damage to your batteries! Only NiMH or NiCd batteries must be inserted into the 9 V chutes A and B. b) Start of Battery Charging Programmes Display after battery chemistry selection:

The input currently required is indicated b y a flashing cursor „>“ in front of „SEL-PRG“ and, depending on the respective programme, in front of „ADJ-CHA“ or „ADJ-DIS“. Within the next 6 seconds, the charge program can be selected with the selection buttons, with the time extending by another 6 seconds with every push of a button. Only after this period will the settings be assumed. VOLTCRAFT CM2016 ================ TYPE OF BATTERY? SLOTS S1-4: NiMH PARAMETERS SLOT1 >SEL-PRG CHARGE ADJ-CHA AUTO ADJ-DIS ---mA45 Briefly pushing „OK“ suffices to confirm at once. If no input is made, the programme „CHARGE“ starts automatically with the automatic charging current setting after approx. 6 seconds. The desired programme is selected with the selection buttons. Five different programmes are available. „SET CHARGE“ = Charging „SET DISCHARGE“ = Discharge (no maintenance charge!) „SET CHECK“ = Discharge -> charge „SET CYCLE“ = Charge -> discharge -> charge „SET ALIVE“ = Charge -> discharge -> charge -> discharge -> charge Description:

• „CHA“ („CHARGE“) means that the inserted battery is being charged.

• „DIS“ („DISCHARGE“) means that the inserted battery will only be discharged. There is no maintenance charge.

• „CHK“ („CHECK“) means that a charge follows the discharge.

• „CYC“ („CYCLE“) means that the inserted battery will be first charged, then discharged and finally recharged.

• „ALV“ („ALIVE“) means that the battery must go through several charge and discharge cycles. The „ALIVE“ programme is used for activating new batteries and batteries that were stored for an extended period of time. Depending on the selected programme and battery type, the charge or discharge current may also be selectable. Otherwise, the programme starts automatically with the pre- settings.46 Entry of Charge / Discharge Current The selection buttons „<“ and „>“ can be used to select the charge current („ADJ-CHA“) first and then the discharge current („ADJ-DIS“). This is also either assumed by the button „OK“ or automatically after 6 seconds. In the above example, the „Charge Manager 2016“ starts with automatic charge current adjustment and discharge current pre-settings of 300 mA if no input is made. Starting additional batteries When adding additional batteries, the last programme selected and possibly values for discharge and charge current are suggested.

If several batteries of the same programme are processed, it is sufficient to select the parameters for the first battery detected. After a waiting time of 6 seconds each, these values are automatically accepted without any button pressed. The selection buttons „<“ and „>“ can be used to call another programme. c) Programme Cancellation To cancel a running programme, the battery has to be removed from the charging chute. PARAMETERS SLOT1 SEL-PRG CYCLE >ADJ-CHA AUTO ADJ-DIS 300mA47

Total overview: Here a display shows all the inserted batteries with their associated programme and charging condition (battery symbol). The „- - -“ lines mean that no battery is inserted in these slots. If the battery is being processed, the battery symbol or an arrow are displayed alternatingly. During charging, the arrow points up; during discharging, it points down. The currently active programme continues to be displayed. If there are batteries in the chutes 1 to 4, line 3 shows the battery chemistry („NiMH“ for NiCd/NiMH batteries or „NiZn“). Detailed view: Use the selection buttons to request details of all available battery data. Push the button „OK“ to return to the total overview. The first line contains the charge slot number („SLOT“) and the charge capacity (C). The second line displays the battery chemistry and discharge capacity (D). In the third line, the currently performed programme (e.g. „CHA“ for „CHARGE“) is displayed, as well as a battery icon („ “) that indicates the approximate charging condition. Furthermore, this line shows the current battery voltage. SLOT1>C=136.4mAh NiMH D= 0.0mAh

The fourth line shows the elapsed processing time in the format „HH:MM“ (hour:minute) and the current charge or discharge current with which the „Charge Manager 2016“ treats the inserted battery. During charging, an arrow flashes in front of „C“, during discharging, the arrow flashes in front of „D“. Charge programme end („RDY“) If the „Charge Manager 2016“ has successfully completed the charge process, the display shows „RDY“ (= „READY“). Display in the overview: Detailed view:

The charge process is completed, the battery can be removed from the charge slot.

01:14 I= 0.000A49 Maintenance Charge („TRI“, „TRICKLE“) Batteries discharge over time. This property is known as self-discharge. To balance out this loss, the „Charge Manager 2016“ starts the maintenance charge programme „TRI“ („TRICKLE“) automatically if needed. Of course, this does not apply if the battery was only discharged with the programme „DIS“ („DISCHARGE“). The capacity (C) of the recharge („TRICKLE“) and the time required for this process („HH:MM“) will not be indicated or summed up. Only voltage and current are updated. Therefore, the charging capacity, if applicable the discharging capacity and the time only refer to the programme processed previously. Display in the overview: Defective battery / wrong battery chemistry („ERR“, „ERROR“) If the charge or discharge process is unsuccessful, the error message „ERR“ („ERROR“) is output (see chapter 15). The charger will no longer process this battery. Display in the overview:

The „Charge Manager 2016“ has a USB interface on the rear of the device (USB-B socket). This USB interface can be used to connect the „Charge Manager 2016“ to a PC and to submit all displayed battery data and parameters to a PC. The corresponding Windows software can be downloaded free of charge at the item page for the „Charge Manager 2016“, www.conrad.com.

By purchasing this charging device you have acquired a product that has been designed to the state of the art and is operationally reliable. Nevertheless, problems or errors may occur. Therefore, we would like to describe to you how to remove possible interferences. No function or no display

• Is the mains adapter correctly plugged into the mains socket and is the mains voltage present?

• Device in power saving mode - push the „OK“ button No battery identified

• Are the contacts of the charge slot or battery contaminated? If required, clean it with a clean, dry cloth.

• The battery has not been inserted properly. Observe polarity! Device temperature too high (display „OVERTEMP!!! Please Wait“)

• The charger is overheated. After the cooling phase, the programme is continued automatically. If required, ensure a cooler ambience temperature (e.g. do not operate the charger at direct sun irradiation).51 Display „ERR“ („ERROR“) for one or several inserted batteries

• A non-rechargeable battery or impermissible battery was inserted accidentally.

• The wrong battery chemistry was selected

• The rechargeable battery is defective.

• If „ERR“ is displayed at the same time for several cells, remove all cells from the charger and charge the cells individually to detect the defective battery. Immediate display „RDY“ („READY“) in programme „DIS“ (DISCHARGE“) or immediate commencement of charging at programme „CHK“) („CHECK“)

• The inserted battery is deep-discharged. Therefore, the discharge process is cancelled to protect the battery. Low charge capacity (C) although the battery was discharged

• Process battery with the „ALV“ („ALIVE“) programme. If the charge capacity „C“ is still too low, the battery is defective. No display in the device display and/or no reaction due to EMC impulses, electrostatic discharge = ESD, surge impulses or line-conveyed interference resistance

• Disconnect the charger from the mains for several seconds and reconnect it. Significant warming on the casing

• The high performance of the device results in heating of the top and bottom of the casing; this is no fault. Ensure good ventilation of the charger.52
