4.
Never completely discharge the Booster's batteries.
The batteries do not have a memory effect.
Danger of irreversible sulphatation.
5.
During the charge, the clamps must never touch a metallic surface.
You may melt one or several poles in the charging plug.
4.2. Starting
1.
Important: on vehicles difficult to start, crank the engine for a maximum of 8-10
seconds and wait for 3 minutes before further attempt to restart the vehicle.
Three reasons:
a. To allow the voltage of the Booster batteries to build up again.
b. To allow the renewal of gasses inside the batteries.
c. To allow the internal components of the batteries to cool down.
If you do not wait and/or the starting attempt is too long, you risk losing power,
you reduce your starting possibilities by the second attempt and you risk melting
the fuse inside.
2.
Never connect the Booster to a battery or starter which is in short-circuit.
3.
Never disconnect the Booster while engine running when there is no battery in
the vehicle or when the vehicle's battery is at 0 volt.
This may cause failure to the diodes of the alternator.
4.
Never place the Booster in short-circuit, for example :
A. By connecting the red clamp (+) to the negative terminal of the battery and
the blue clamp (-) to the vehicle's earth.
The inversion of polarity signal will not operate because you are connected
2x to the mass and you are not in inversion of polarity.
