GRAUPNER SJ ULTRA DUO PLUS 80 Instructions D'utilisation page 32

Do not connect more than one charger to a multiple-output mains socket - danger of overloading the socket: fire hazard!
The charger is designed to be powered by a 12 V car battery or power supply (11...28 V DC) only. Never connect an A.C. voltage to the D.C. input. Fire
hazard! It is not permissible to modify the charger in any way.
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!!
Connect the charger 12 VDC input directly to the car battery using the original cables and connectors supplied. The car's engine must be stopped all the
time the charger is connected to the car's battery! Do not recharge the car battery at any time when the charger is connected to it!
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 to the unit for charging at any one time.
The following types of battery must not be connected to the charger:
• NiCd- / NiMH batteries consisting of more than 18 cells, LiFePO /Lithium-Ion/LithiumPolymer batteries of more than 7 cells or PB batteries of more than 12 cells.

• Batteries which require a different charge method from Ni-Cd, Ni-MH, Lithium or Pb 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 fi tted 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 fi tted to the charge leads, please always connect the charge leads to the charger fi rst, and only then to the
battery to be charged. Reverse the sequence when disconnecting.
