e.g: 6VLead-acid battery: Constant current = 7Ah = 1.4A

WARNING AND SAFETY NOTES

• This product isn't designed for use by children under the age of 14, it isn't a toy! This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
• Protect the charger from dust, damp, rain, heat (e.g. direct sunshine) and vibration. It should only be operated in dry indoor conditions.
• The case slots serve to cool the charger, and must not be covered or enclosed; set up the charger with space round it, so that cooling air can circulate unhindered.
• The charger is designed to be powered by a 220~240V AC main socket only. It is not permissible to modify the charger in any way. You must not connect AC power to the DC input.
• The charger and the battery to be charged should be set up on a heat-resistant, non-inflammable and non-conductive surface before use. Never place the charger directly on a car seat, carpet or similar. Keep all inflammable and volatile materials well away from the charging area. Provide good ventilation. Defective batteries can explode or burn!
• The charge output sockets and connecting leads must not be modified, and must not be inter-connected in any way. There is a danger of short-circuit between the charge outputs and the vehicle's bodywork when the charger is connected to the car battery. The charge leads and connecting leads must not be coiled up when the charger is in use. Avoid short-circuiting the charge output or the model battery with the car bodywork. For this reason the charger must never be placed directly on the vehicle's bodywork.
• Never leave the charger running or connected to the car battery unsupervised.
• Only one battery may be connected at each output at any one time.

• The following types of battery must not be connected to the charger:

• Ni-Cd / Ni-MH batteries, lead-acid batteries with a nominal voltage of more than 12V or less than 6V, Lithium-Ion / Li-Mn / Lithium-Polymer / LiFePO_4 (LiFe) batteries with less than 2 cells and more than 3 cells (4 cells for LiFePO_4 ).

• Batteries which require a different charge method from CC/CV or lead-acid types.
• Faulty or damaged cells or batteries.
• Batteries consisting of parallel-wired cells, or cells of different types.
• Batteries consisting of old and new cells, or cells of different makes.
• Non-rechargeable batteries (dry cells). Caution: explosion hazard!
• Batteries which are not expressly stated by the manufacturer to be suitable for the currents which this unit delivers during the charge process.
• Packs which are already fully charged or hot, or only partially discharged.
• Batteries or cells fitted with an integral charge circuit or charge termination circuit.

• Batteries installed in a device, or which are electrically connected to other components.

• To avoid short-circuits between the banana plugs fitted to the charge leads, please always connect the charge leads to the charger first, and only then to the battery to be charged. Reverse the sequence when disconnecting.

• As a basic rule always check that the charge quantity is approximately the same as you expected after the charger has indicated that the pack is fully charged. This is a simple method of detecting a problem reliably and in good time, should the charge process be terminated prematurely for any reason. The likelihood of premature termination varies according to many factors, but is at its highest with deep-discharged packs, low cell counts and particular cell types which are known to cause problems.

• We recommend that you carry out a series of test charges to satisfy yourself that the automatic termination circuit is working perfectly. This applies in particular when you are charging packs consisting of a small number of cells. If the cells feature has a poorly defined voltage peak, the charger may fail to detect the fully charged state.

• Before charging please check: have you selected the appropriate charge output for the battery? Are all connections firm, or is there an intermittent contact at any point in the circuit? Please bear in mind that it can be dangerous to fast-charge batteries. For example, if there is a brief interruption due to an intermittent contact, the result is inevitably a malfunction such as a restart of the charge process, which would result in the pack being massively overcharged.
• Be careful! A battery could explode or burn, if the charger does have a fault or if the user does choose the wrong charging output and parameters.

4. Operation:

1. Connect the charger to an easily accessible mains power socket (220-240V AC, 50Hz). The red LED display will be on to confirm that the charger is ready for use.

Adjust the max. charge current and charge voltage like shown in the table.

Doing not so or adjusting the wrong voltage or current can cause explosion and fire.

1. Make absolutely sure that the polarity of the battery and the polarity of the charging cable match.

2. RED to positive pole (+)

3. BLACK to negative pole

The charge current can be displayed in the LED display to indicate that charging is in progress.

1. If the charge current is lower as 0.1 - 0.2A , the battery is fully charged. Disconnect the battery from the charge lead, and disconnect the charger from the mains socket.
2. In case of charging LiFe or LiPo batteries, you must use the LiPo-Balancer 5 plus #3064 or LiPo-Balancer 6 plus #3065 for safety reasons. The maximum charge current must be limited to max. 10 A. Use a LiPo safety case #8370 or #8371.

5. Safety notes:

Make sure to follow the correct polarity connecting the battery charger. In case of wrong connection you could cause severe damages to the battery charger connected.
Protect the charger from dust, damp, rain, heat (e.g. direct sunshine) and vibration. It should only be operated in dry, indoor conditions.
The case surface serves to cool the charger and must not be covered or enclosed; cooling air must be able to circulate unhindered.
Do not leave the charger running unsupervised.
Power supply may become warm during use or emit a slight buzzing sound, this is normal and can be disregarded.
Do not attempt to open the casing, as there are no user serviceable parts inside, and this may void the warranty.
For indoor use only.
The following types of battery must not be connected to the charger:

• Faulty, damaged or hot batteries
• NiMH or NiCd batteries

• Non-rechargeable batteries (dry cells)

• Caution: explosion hazard!

• Batteries which are not expressly stated by the manufacture to be suitable for the currents which the unit produces during the charge process.

• Batteries which are already fully charged or hot, or only partially discharged.

• Batteries fitted with an integral charge circuit or charge termination circuit.
