After twice going flat when the car was not used for a few days I concluded that the battery in my 2014 dCi auto was on its last legs.
As the second occurrence was last night when my wife was going to go out (I ended up taking her in my car) and as I am aiming to be out all day Saturday, instead of using up lots of my time going to get it changed I decided for the first time ever to buy a new battery and change it myself.
Renault may have changed the method of mounting etc on later cars but for my car, not fitted with start-stop, still needed an "EFB" battery and not just a standard lead-acid one. This is apparently due to the "smart recharging" technology built into the car. I bought from GSF and they would not warrant the cheaper lead--acid one as they said it was not suited to the car.
You will need:
Your radio code
Torx driver to remove the battery clamp (T40 IIRC)
9mm spanner
10mm spanner
I started by pulling out the small-diameter vent tube from the side of the battery, loosening the battery clamp, then removing the black wire from the negative terminal using a 9mm spanner. You then need a 10mm spanner to remove the negative battery terminal clamp and the wire/connector assembly that is attached.
Next 9mm spanner again to remove the red wire from the positive terminal.
I then removed the clamp and took the battery out - pull it slightly towards the front of the car to release it then lift straight up.
Then when out of the car you can use a 10mm spanner to remove the clamp from the positive terminal and transfer it to the new battery.
Fit the new battery into the car by placing it into the tray and push it rearwards, then fit the clamp. Reconnect the positive wire, then the negative clamp and then the negative wire. Push the vent tube back in.
Start the car (I chose to leave the driver's door open all through the change process to prevent the central locking from unintentionally activating, but closed it before starting the engine). Put the radio code in, operate all 4 electric windows in turn fully down then up and - hey presto !
No photos (sorry) as I did it all in the dark using the light from my garage and an LED magnetic "universal" torch.
