194Checking and refilling levels
–After charging the battery: Switch off the battery charger and
disconnect the cable.
– Remove the charger cables.
– If necessary, reconnect both battery cables to the battery (first
the “positive” cable, then the “negative” cable).
When charging with a low current (e.g. with a small battery charger), the
battery does not have to be disconnected. The instructions of the battery
charger manufacturer must be followed.
Use a current equivalent to or lower than 10% of the battery capacity to fully
charge the battery.
Before “fast-charging” the battery however, both battery cables must be
disconnected.
“Fast-charging” a battery is dangerous and requires a battery charger and
special knowledge. Fast charges should be performed by an official techni-
cal service.
The battery caps should not be opened while the battery is being charged.
CAUTION
In vehicles fitted with the “START-STOP” system, the charger cable cannot
be directly connected to the negative terminal of the vehicle battery but
must be attached to the engine earthing point ⇒ page 216.
Disconnecting and connecting the battery
The following functions will either be inoperative or will not work properly
after disconnecting and reconnecting the battery:

Note
We recommend having the vehicle checked by an authorised SEAT dealer to
guarantee the correct working order of all electrical systems.
Changing the battery
A replacement battery must have the same capacity, voltage, current rating
and size as the original. The appropriate types of battery can be acquired
from authorised SEAT dealers.
We recommend having the battery changed by an authorised SEAT dealer,
where the new battery will be correctly installed and the original disposed
of in line with regulations.
Automatic disconnection of electrical equipment
When heavily-charging a battery, the programme selected by the electrical
system control unit prevents the battery from automatically discharging.
This may result in the following:
● Increase in idling speed so that the alternator can supply more current
to the electrical system.
● The performance of certain electrical components could be limited or
some may switch off temporarily, e.g. the heated seats, the heated rear win-
dow, the 12V power socket.
