Practical advice -> Battery (Breakdown / Charging) for Your Renault Megane SUV First Generation (1995-2002)

BATTERY (breakdown)  
In the event of an incident  
Isolate the battery by unscrewing  
one of the terminals.  
To avoid all risk of sparks  
- Ensure the “accessories” are  
disconnected before disconnecting  
or reconnecting the battery.  
- When charging, stop the charger  
before connecting or disconnecting  
the battery.  
- Do not place metal objects on the  
battery to avoid creating a short  
circuit between the terminals.  
Take care when moving the  
battery as it contains  
sulphuric acid which must  
not come into contact with  
the eyes or skin. If it should, wash  
the affected area with plenty of  
cold water.  
Keep all flames, red-hot objects and  
sparks away from the battery as  
there is a risk of explosion.  
Take care when working in the  
engine compartment as the cooling  
fan may cut in at any time without  
warning if the engine is hot.

BATTERY: Breakdown (continued)  
Connecting a battery charger  
Both battery leads must be  
• When the external temperature  
drops (in winter), the charge  
declines. In winter, only use those  
electrical consumers which are  
really necessary.  
If your vehicle is to be left stationary  
disconnected (engine switched off).  
for  
a
relatively long time,  
disconnect the battery or have it  
recharged regularly, in particular  
Do not disconnect the battery when  
the engine is running. Follow the  
instructions for use given by the  
manufacturer of the battery charger  
you are using.  
during  
cold  
weather.  
The  
equipment with a memory, radio  
and trip computer will then have to  
be reprogrammed. The battery must  
be stored in a cool dry place,  
protected from frost.  
• Finally, you should understand  
that  
the  
charge  
decreases  
naturally as a result of certain  
permanent consumers such as:  
the clock, after sales accessories,  
etc.  
Only  
a
well-charged  
and  
well-maintained battery will have a  
long and useful life and enable you  
to start the car’s engine normally.  
When a large number of accessories  
are fitted to the vehicle, have them  
connected to + after ignition. In this  
case, it is advisable to have your  
vehicle fitted with a battery which  
has an increased nominal capacity.  
Consult your RENAULT Dealer.  
The battery must be kept clean and  
dry.  
Have the battery's charge status  
checked regularly:  
• especially if you use your vehicle  
for short journeys or for frequent  
driving in town.  
Specific procedures may  
be required to charge  
some batteries. Consult  
your Renault Dealer.  
Avoid all risk of sparks which  
may cause an immediate  
explosion and charge the battery  
in a well-ventilated area. Risk of  
serious injury.

BATTERY: breakdown (continued)  
Check that there is no contact  
between cables A and B and that  
cable A (+) is not touching any  
metal parts on the vehicle  
supplying the current.  
Starting the vehicle using the  
battery from another vehicle  
Proceed as follows when starting  
your vehicle from another vehicle’s  
battery:  
Obtain suitable jump leads (with a  
large cross section) from a Renault  
Dealer or, if you already have jump  
leads, ensure that they are in perfect  
condition.

Start the engine as you would  
normally. As soon as it starts,  
B
disconnect cables  
A
and  
B
in  
A
reverse order (4-3-2-1).  
The two batteries must have an  
3
identical 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 discharged battery.  
2
Secure the positive cable (+) A to  
the (+) terminal 1 of the discharged  
battery, then to (+) terminal 2 of the  
battery supplying the current.  
An iced-up battery must be thawed  
out before current is supplied to it.  
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.  
Secure the negative cable (–) B to  
the (–) terminal 3 of the battery  
supplying the current and then to  
the (–) terminal 4 of the discharged  
battery.  
Switch off your vehicle ignition.  
Start the engine of the vehicle  
supplying the current and run it at  
an average speed.
