Practical Advice -> Battery: troubleshooting for Your Renault Captur SUV Second Generation (2019-2026)

BATTERY: troubleshooting (1/3)  
To avoid all risk of sparks:  
Connecting a battery charger  
– Ensure that any power consumers  
(courtesy lights, etc.) are switched  
off before disconnecting or recon-  
necting a battery;  
The battery charger must be com-  
patible with a battery with nominal  
voltage of 12 volts.  
Do not disconnect the battery when the  
engine is running. Follow the instruc-  
tions given by the manufacturer of  
the battery charger you are using.  
– when charging, stop the charger  
before connecting or disconnecting  
the battery;  
– do not place metal objects on the  
battery as this could create a short  
circuit between the terminals;  
Handle the battery with care  
as it contains sulphuric acid,  
which must not come into  
contact with eyes or skin. If  
it does, wash the affected area with  
plenty of cold water. If necessary,  
consult a doctor.  
– always wait at least five minutes  
after the engine has been switched  
off before disconnecting a battery;  
– make sure that you reconnect the  
battery terminals after refitting.  
Keep naked flames, red hot objects  
and sparks away from the battery  
components as there is a risk of  
explosion.  
Special procedures may be  
required to charge some  
batteries. Contact your ap-  
proved dealer.  
Please note when working close to  
the engine that it may be hot. In ad-  
dition, the engine cooling fan may  
start at any moment. The  
warning light in the engine compart-  
ment reminds you of this.  
Avoid all risk of sparks which may  
cause an immediate explosion, and  
charge the battery in a well venti-  
lated area.  
Risk of injury.  
Before carrying out any  
action in the engine com-  
partment, you must switch  
off the ignition. 2.4

BATTERY: troubleshooting (2/3)  
Starting the vehicle using the  
battery from another vehicle  
If you have to use the battery from an-  
other vehicle to start, obtain suitable  
jump leads (with a large cross section)  
from an approved dealer or, if you al-  
ready have jump leads, ensure that  
they are in perfect condition.

The two batteries must have an iden-  
tical nominal voltage: 12 volts. The  
battery supplying the current should  
have a capacity (amp-hours, Ah) which  
is at least the same as that of the dis-  
charged battery.  
Ensure that there is no risk of contact  
between the two vehicles (risk of short  
circuiting when the positive terminals  
are connected) and that the discharged  
battery is properly connected. Switch  
off your vehicle ignition.  
Battery in engine compartment  
The battery is not directly accessible.  
Use the terminal 1 (+) and the termi-  
nal 2 () in the engine compartment.  
Raise the cover 3 of the terminal 1 (+).

Attach the positive cable A to the ter-  
minal 1 (+) then to the terminal 5 (+) of  
the battery supplying the current.  
Attach the negative cable B to the ter-  
minal 4 () of the battery supplying the  
current and then to the terminal 2 ().  
Check that there is no con-  
tact between leads A and B  
and that the positive lead A  
is not touching any metal  
parts on the vehicle supplying the  
current.  
Risk of injury and/or damage to  
the vehicle.
