Connection and disconnection completely discharged or faulty battery
on your car while engine is running can destroy electronic devices of
your car and car alarm due short circuit or surge overvoltage occurring
when connecting/disconnecting the battery.
In the case of using the above devices and modes, the responsibility for
damage the electronic equipments rests with the car’s owner.
Keep the safe charging battery technology
Before charging the battery terminal must be disconnected from the
onboard network of the car. After that you can start the process of
charging the battery. After charging, connect the battery to an onboard
network of the car.
This need has been reasoned that without measuring devices you
can’t determine the serviceability, battery status, and the reason
for its discharge (availability of internal short circuits or breaks). Any
charger device connection to the unserviceable battery causes the risk
of damage the car’s electronic equipments and car alarm with a high
voltage.
