(D Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected .
@ Tips
The discharged battery must be properly con­
nected to the vehicle's electrical system.
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negative ground cable to the negative ground
post of the battery manager control unit.
