IMPORTANT
•All vehicles are equipped with low water consumption batteries. Opening the battery and topping up the electrolyte
level are PROHIBITED.
•Batteries contain sulphuric acid, which is a hazardous chemical.
•Battery charging produces hydrogen and oxygen, which are very flammable gases and thus there is a risk of
explosion.
•Any batteries with filling plugs must not be opened under any circumstances but replaced immediately with Renault
approved batteries.
Battery recharging:
When parked, vehicles consume power through their permanent consumers and through any accessories fitted as
After-Sales options. To keep battery discharging to a minimum, limit the number of times the vehicle is started,
periods with the ignition on, doors open, etc., as much as possible.
A discharged battery must be recharged using a Renault-approved battery charger (see Technical Note 6512A,
Battery charging)
Battery storage:
Even when stored off the vehicle, a battery gradually discharges, and more rapidly if the ambient temperature is
high.
In order that a battery remains operational for a long time, it must be stored at a temperature of around
15 ˚C and protected from humidity.. To retain a good level of charge, it is recommended that a battery is completely
recharged after it has been stored for 3 months.
A new battery that has been stored for more than one year must not be fitted to a vehicle.IMPORTANT
•Simultaneous recharging of several batteries in series or in parallel is forbidden.
•A battery charger used on a battery connected to a vehicle can irreparably damage the vehicle computers due
to the high voltages created when charging.
•The location of the charger must take this into account (ventilation).
•A battery charger or a booster not approved by Renault can damage the electrical components.
