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.

Mode (test on vehicle)
–Connect the tool directly to the battery terminals, without disconnecting the vehicle battery, as close as possible to
the battery terminal but ensuring it is not after the fuse (on-vehicle test) or carry out the battery test after
disconnecting the two terminals if necessary,
–check that the vehicle ignition is switched off,
–select the type of test: "battery connected to vehicle" or "battery disconnected" using
buttons and . Confirm using the green button .
–The test is carried out to the EN standard by default. Confirm using the green button .
–Select the starting power inscribed on the battery label (see page 3) using
buttons and .
–Confirm using the green button
–The tool displays TEST IN PROGRESS.
–The MIDTRONICS tool carries out the test and gives the results of the fault finding procedure.
To set the tool language, carry out the following operations:
–before connecting the tool, simultaneously press buttons and ,
–connect the device to the battery,
–release the buttons,
–scroll through the languages using buttons and ,
–confirm using the green button .
