Battery – Advice
IMPORTANT
•All vehicles are equipped with low water consumption batteries. Opening the battery and topping up the
electrolyte are FORBIDDEN.
•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 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 in a dry place. 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.

TEST Testing the battery
Check whether or not the engine has been running in the past hour.
Has the engine been running in the past hour?
Switch off the engine and remove the key to interrupt the + after ignition feed
and illuminate the main beam headlights for2minutes.Then switch them off
and wait2minutes.
Carry out a battery test using the MIDTRONICS tool (the information requested by the MIDTRONICS tool is
provided on the battery label)

electrical and dimensional specifications
(see MR 411, Mechanical systems, 80A, battery,
Battery: Removal - Refitting).
Start the vehicle again.
Does the vehicle restart?
