Schumacher Electric SL1452 Manuel D'utilisation page 10

NOTE: Cold weather may affect the performance of the jump starter's
lithium battery. If you hear only a click and the engine does not turn
over, try the following:
With the jump starter connected to the car battery and the green LED
illuminated on the smart cable, turn on all lights and electrical accessories for
one minute. This draws current from the jump starter and warms the battery.
Now try to crank the engine. If it does not turn over, repeat the procedure.
Extremely cold weather may require two or three battery warmings before
the engine will start.
NOTE: If no activity is detected, the smart cable will automatically shut
off after 90 seconds, and the red and green LEDs will be solid. To reset,
disconnect the clamps from the vehicle battery, and then reconnect.
IMPORTANT: DO NOT attempt to jump start your vehicle more
than three consecutive times. If the vehicle will not start after three
attempts, consult a service technician.
7. After the engine starts, unplug the battery clamps from the jump
starter socket and then disconnect the black clamp (-) and the red
clamp (+), in that order.
8. Recharge the unit as soon as possible after each use.
