A car battery has a certain service life, after which the battery begins to gradually fail. As a result, at the most inopportune moment, the car may simply stop starting. This means that you can no longer put off replacing the battery. The procedure for replacing an old battery with a new one does not require a trip to the service: a new battery can be installed independently in a short time.
What usually happens when removing a battery
Every car owner has to deal with removing the battery, the reasons for this may be different. Be it replacement, maintenance or temporary storage during the winter, if the car is not used for a long time. Such a seemingly simple manipulation can lead to unpleasant consequences in the form of settings failure.
Basically, modern models stuffed with electronics are susceptible to this. First of all, the settings of the on-board computer and clock are lost, the power windows, the multimedia system and other components of the components “die”. It will take time to bring everything back to its original state. However, by knowing a few simple rules and following consistency, such problems can be avoided.
Terminal design
Typically the terminals are located at the top of the battery. To properly disconnect the wires, you need to use several options:
- The first option is the simplest - unscrew the nut located on the terminal.
- The second option is more complicated - you need to get rid of the spring clamp.
We recommend: How much electrolyte is needed and can be added to the battery To unscrew the nut , use a regular 10mm socket wrench. In the second option, regular pliers are used.
These tools should be in the glove compartment of every car. After the preparatory work, it is necessary to study the basic parameters of the battery . To do this, the battery is inspected - looking for markings. It is necessary to write down or remember the audio system code, which is then entered when installing a new battery. By saving such a code, you can prevent the player from being stolen. If the code is lost, it can only be restored at a special service station.
Saving settings
There are many ways to do this. The most effective:
- Manufacturers have released systems that allow the electronics to remain on even when the battery is disconnected. All you need to do is connect the compact, easy-to-use device via the cigarette lighter socket. During use, the gadget blocks the engine from starting, and therefore the electronics will not turn on. Expensiveness is the only drawback of a “smart” device.
- The problem can be solved in a simpler and more accessible way. Namely: Connect the wire from any device, for example, charging a mobile phone or heating a seat, which previously operated from a device used to light cigarettes while driving in a car, to the Krona battery by inserting it into the cigarette lighter. You don’t have to worry about the safety of your settings for at least a couple of days. This time is enough to replace the old battery with a new one.
- The third, popular option is to use wires intended for lighting the cigarette and the “donor” car. Before removing the battery, the cigarette lighter wires are secured above the terminals of the battery being removed.
Installing a new battery
Once the old battery has been safely removed, you can begin installing the new battery.
- It is recommended to first inspect the battery area, removing dirt and debris with a soft cloth.
- Clean the inner surfaces of the wire tips with sandpaper - this will ensure good contact with the terminals. The wires can also be treated with a water-repellent liquid.
- The terminals themselves, which may have oxidized over a long period of time, are cleaned with a toothbrush dipped in a baking soda solution.
What to do if the original battery is not enough
Modern cars already require multiple batteries. But so far this has been implemented in specialized vehicles and models with a powerful generator. The rest have to resort to makeshift methods to install an additional power source.
In most cases, the difficulty lies in choosing additional installation space and correct connection. The advantage of the method is obvious: By installing an additional battery, you can forget about frequent battery changes.
Preparation
- Most cars have a battery under the hood.
- For example, BMW and TOYOTA Prius have it in the trunk.
- Volkswagen Touareg cars have it under the driver's seat.
- In AUDI it sometimes occurs under the rear passenger seat.
Open the hood and leave it for a while to ventilate the engine compartment. The fact is that when the battery is charging, gas can be released, which is explosive and harmful to health, and many people lay a blanket over the engine in winter; all this must be removed so that the gas can evaporate freely. Let's leave it for a few minutes so that the gas evaporates and prepare the new battery for use.
First of all, remove the packaging film, if present. Many people leave thinking that it will somehow help, but in fact, moisture forms under it, dust and dirt become clogged, and all this only contributes to the self-discharge of the battery. Next, I remove the protective plastic caps. Some car enthusiasts leave them and put terminals on top, which is why their battery stops working. This happens rarely, mainly among beginners who decided to make the replacement themselves for the first time.
Connection rules
Having figured out how to replace the battery in a car without losing the settings, let’s get started:
- It is important to understand that you cannot disconnect the connections of the battery terminals as you please, the order is of great importance. First of all, the “plus” is connected and only then the “minus”. The manufacturer recommends doing exactly this and not otherwise. Thereby preventing short circuits.
- In essence, the body is the “mass” of the car. If you start disconnecting from the “plus”, there is a high probability of accidental contact of the car with the wrench, which will inevitably lead to a short circuit. As a result, sad consequences in the form of burnt out wires, fuses and failure of active electrical appliances cannot be avoided.
How to properly replace the battery in a car without harming the on-board network?
Car electric battery
, also known as
a battery
, is
a rechargeable acid battery
that is part of
the electrical circuit
of any modern vehicle.
The battery in a car performs the important function
of
supplying
electricity to
the starter
, as a result of which
the power unit
starts We recommend reading the article: “ How to safely charge a car battery with your own hands?
".
{banner_adsensetext} As a rule, a standard battery
produces a voltage of
12
Volts, which is quite enough to power the on-board network in a passenger car.
In turn, any battery has a certain capacity
, which is measured in
Ampere-hours
(A*h).
For example, battery batteries
for passenger cars are equipped with battery batteries with
a capacity
ranging from 40-130 Ah.
Thus, the capacity
shows
how long
the battery is capable of
delivering
energy at
maximum
load.
As a rule, vehicle owners quite often ask the pressing question: “When replacing the battery, is it possible to completely de-energize the vehicle’s on-board network?”
Of course, for the majority of cars this is possible and in itself completely harmless
, as well as “painless”.
However, it must be said that for some modern cars, which are literally
crammed with
various
electronics
, for example, such as navigation, multimedia systems, on-board computer and much more, it is still necessary to
simultaneously
connect
a second
battery before removing the old one.
By taking similar actions, namely connecting
a second or spare
battery
, as indicated above, you will ensure
all current
settings
are saved in certain
electronic
standard
systems
.
In addition, according to auto experts,
is still highly
recommended not
types of .
You should also pay attention to the fact that errors
and
problems
in the settings of on-board
electronic
devices after
incorrectly
disconnecting the battery.

What is the correct procedure for replacing the battery?
So, if you have a budget-class car that
does not have
an on-board computer and other modern electronic devices, then
replacing
and
installing
a
new
battery will not be difficult and will not harm the standard electronics.
So, we bring to your attention clear
step-by-step instructions
for
replacing
the battery
yourself
.
The first thing you need to do is remove
first the “
negative
” terminal, and then the “
positive
” terminal.
Next, remove
the battery from the engine compartment and, if necessary
clean
traces of oxides
on them .
After this,
we install
the new
battery
in the same place where the old one was.
In this case, be extremely careful, since terminals
must
be connected
in
the reverse
order - the “
positive
” one is clamped first and only then the “
negative
” one is attached.
For reference, we note that it is necessary to pay close attention to one important feature, if the car is equipped with
an alarm
or
central locking
and/or
immobilizer
, then in this case, when
connecting
the battery, it is best to open the doors and also remove the keys from the car, since at the time of
installation
, the door lock and steering wheel lock may be activated.
After
installing
a new
battery
, first check that it
properly
, and also whether there are any
notifications
on the car’s on-board computer about
an error
when turning on the ignition.
In principle, these are all the steps necessary to correctly install
a new battery.

In conclusion, we note that, as we described in the article above, for certain car models it is still not recommended to completely de-energize the battery from the mains, therefore, before disconnecting the old battery, it is necessary to connect the network from a second power source for this purpose Another similar battery may be suitable.
In this case, you need to connect at the same time, that is, “minus” - to “minus”, and “plus” - to “plus”. THANK YOU FOR YOUR ATTENTION
