Introduction
How to replace your car battery simply and safely.
Please note that modern vehicles equipped with numerous computers require careful handling. A rest period is necessary before disconnecting the battery (3 to 15 minutes depending on the model, to be checked in your maintenance manual sold with the vehicle). This same step is mandatory after changing the battery, before restarting the engine, or even opening the door for certain models.
Video Overview
-
-
Your vehicle's battery is located in the engine bay and may be protected by a plastic cover that must be removed while it is being replaced.
-
Some batteries may also be located in the trunk, under the passenger and driver seat, or even under the back seat.
-
-
-
Your battery is connected to your vehicle by two terminals, a + and a -
-
Start by removing the terminal - to avoid any risk of short circuit with the tool
-
In case no tools are needed for the + terminal (limited risk). So you have to start by removing the + , common thing on modern vehicles
-
-
-
A mounting plate prevents the battery from moving and becoming disconnected
-
Remove the mounting plate to release the battery
-
-
-
Using the handle on the battery, remove the battery from its location by pulling it upwards.
-
-
-
Compare the dimensions of the new battery to the old one, it is important to keep the same template otherwise the battery may not fit if too big or impossible to fix if too small
-
There are 3 values to check before purchasing the new battery:
-
Voltage (V): the voltage delivered by the battery, mostly 12 Volts for cars.
-
Ampere-hour (Ah): Represents the battery's ability to hold a charge over time, here 62Ah. We must choose a battery with the same amperage or as close as possible to it.
-
Amperage (A): Represents the power delivered by the battery at the time of starting, a less powerful battery will probably not be able to start your vehicle.
-
We therefore choose to change to a 12V - 62Ah - 560A battery, against 12V - 62Ah - 500A previously. The new battery is therefore more powerful but retains its storage capacity, voltage and of course its size.
-
-
-
Replace the + terminal in first gear
-
Except for modern vehicles which require termination with the + terminal
-
You can take this opportunity to check the condition of your terminals, clean them if necessary
-
-
-
Replace the terminal -
-
Push the terminal in correctly if necessary.
-
Tighten the terminal
-
-
-
Start the vehicle to ensure the battery is working properly
Hello everyone
Very nice, well-illustrated demonstration, but the demonstrator speaks a little dryly and quickly and is sometimes difficult to understand.
You do not specify the precautions to take on a car like mine SKODA, apparently you have to connect a battery before dismantling so as not to disturb the on-board computer.!
So, not having any instructions for this manipulation, I will abstain for the moment, unless you provide an explanation.
THANKS
Sincerely
DAILLIEZ
This is not the battery that fits my camper van

Changing on scenic 3 a bit of a hassle but honestly 30 min everything is done. When plugging in message “new battery?” just put yes and that's it. All the electronics reboot and it's off again
Good morning,
On my automatic Mercedes B-Class, you need to have the fingers of a midwife, a small suitcase and not have back pain. Two workers worked on it for half an hour. For my car, the tutorial for replacing it does not correspond at all to reality. It cost me more but I left satisfied and calm.
the tutorial is dated, modern cars are something else..
I am a very loyal customer of Oscaro… but here, the Tutorial is perfect for a car from the 80s… Could do better!!!
This tutorial is not at all suitable for the Ford Kuga II 4X4 180CV.
I have a Jaguar S Type 2.7L diesel and cannot unlock the electric parking brake. I am advised to change the battery, except the one in place is two years old. What should I do please?
Also redo the code for the radio/cd if necessary.
Thanks for the tutorial!
With the on-board electronics deprived of power for the necessary 1/4 hour, some vehicles will not start, others will need to be reset. It smells like “the suitcase” …
I usually do this with another battery connected by jumper cables to the vehicle's battery cables.
I'm looking for one of those little boxes that you plug into the cigarette lighter socket and I haven't found one.
This is a “basic” tutorial because on some vehicles, it is mandatory to use the “home” tool to code the battery on the car’s computer, otherwise there is a risk of malfunction, particularly concerning the start/stop.
