General Maintenance -> Battery for Your Skoda Octavia 4 Door Second Generation (2004-2012)

232 Inspecting and replenishing  
We recommend that you have the brake fluid replaced by a Škoda Service Partner  
as part of an Inspection Service.  
WARNING  
•
Using old brake fluid can result in severe stress on the brakes because of  
the formation of vapour bubbles in the brake system. This greatly impairs  
the braking efficiency and thus also the safety of your vehicle.

•
Brake fluid is toxic! It must therefore be kept safely in closed original  
containers and well away from children and unauthorized persons.  
Caution  
The battery is located in the engine compartment in a polyester cover or  
in a plastic cover*.  
Brake fluid damages the paintwork of the vehicle.  
–
Open the battery cover in direction of arrow ⇒ fig. 214 or press the  
interlock on the side of the battery cover ⇒ fig. 215, fold the cover up  
and remove the battery.  
For the sake of the environment  
In view of the problems involved with proper disposal of brake fluid, the special  
tools and the professional knowledge required, you should have the brake fluid  
replaced by a Škoda Service Partner.  
–
The installation of the battery cover takes place in the reverse order.  
Removal and installation of the battery is not recommended since it can, under  
certain circumstances, lead to major damage. Contact a specialist garage.  
Battery  
There is a risk of injuries, scalding, accidents and burns when carrying out any work  
on the battery and on the electrical system. For this reason, it is essential to comply  
Working on the battery  
with the warning instructions ⇒  
stated below and with the general applicable  
rules of safety.  
WARNING  
•
The battery acid is strongly corrosive and must, therefore, be handled  
with the greatest of care. Always wear protective gloves, eye and skin  
protection when handling batteries. Corrosive fumes in the air irritate the  
air passages and lead to conjunctivitis and inflammation of the air passages  
in the lungs. Battery acid corrodes dental enamel and creates deep wounds  
after contact with the skin which take a long time to heal. Repeated contact  
with diluted acids causes skin diseases (inflammations, ulcers, slin cracks).

Inspecting and replenishing 233  
WARNING (continued)  
Caution  
You must only disconnect the battery if the ignition is switched off, otherwise  
the electrical system (electronic components) of the vehicle may be damaged.  
When disconnecting the battery from the electrical system of the vehicle, first  
disconnect the negative terminal (-) of the battery. Then disconnect the positive  
terminal (+).  
Acids coming into contact with water are diluted accompanied by significant  
development of heat.  
•
•
Do not tilt the battery otherwise battery electrolyte may flow out of the  
battery vent openings. Protect the eyes with safety glasses or a shield! There  
is the danger of suffering blindness! If any battery electrolyte gets into your  
eye, rinse out your eye immediately with clear water for several minutes.  
Contact a doctor without delay.  
•
When reconnecting the battery, first connect the positive terminal (+) and only  
then the negative terminal (-) of the battery. You must on no account connect the  
cables wrongly - risk of a cable fire.  
•
Splashes of acid on your skin or clothes should be neutralised as soon as  
possible using soap suds and then rinsed with plenty of water. Contact a  
doctor immediately if you swallow battery electrolyte.  
•
Ensure that battery acid does not come into contact with the vehicle body  
otherwise damage could occur to the paintwork.  
Do not place the battery in direct daylight in order to protect the battery  
•
•
Keep batteries out of the reach of children.  
•
housing from the effects of ultra-violet light.  
Hydrogen is released when you charge a battery and a highly explosive  
gas mixture is produced. An explosion can be caused through sparkling over  
during unclamping or loosening of the cable plug while the ignition is on.  
For the sake of the environment  
A removed battery is a special type of waste which is harmful to the environment -  
contact your specialist garage regarding disposing of the battery.  
•
Bridging of the poles will create a short circuit (e.g. through metal  
objects, cables). Possible consequences of a short circuit: Melting of lead  
struts, explosion and burning of the battery, jets of acid spurting out.  
•
It is prohibited to work with a naked flame and light, to smoke or to carry  
out any activities which produce sparks. Avoid creating sparks when  
working with cables and electrical devices. Strong sparking represents a risk  
of injury.  
Note  
Please also refer to the guidelines ⇒ page 236, also after connecting the battery.  
•
Before carrying out any work on the electrical system, switch off the  
engine, the ignition as well as all electrical components and disconnect the  
negative cable (-) on the battery. If you wish to replace a bulb it is sufficient  
to switch off the appropriate light.  
•
Never charge a frozen or thawed battery - risk of explosion and caustic  
burns! Replace a frozen battery.  
Never jump-start the batteries which have a too low electrolyte level -  
risk of explosion and caustic burns!  
Never use a battery which is damaged - risk of explosion! Immediately  
replace a damaged battery.

Battery with a two-tone indicator  
Note  
•
Batteries with two-tone indicator, which are mounted as of factory, are marked  
with a code which always begins with 5K0. The exact marking can be e.g.  
5K0 915 105 D.  
•
Replacement batteries with two-tone indicator, which were obtained from  
Škoda original accessories, are marked with the code 000 915 105 Dx, whereby  
“x” stands for a variable. The exact marking can be e.g. 000 915 105 DB.  
Battery with a three-tone indicator  
Fig. 216 The battery: Show  
An indicator for the electrolyte level and the charge state, the so-called magic eye  
⇒ fig. 216, is located on the top of the battery. The indicator changes its colour in  
line with the charge state of and the electrolyte level in the battery.

Green colour - the battery is adequately charged.  
Dark colour - the battery has to be charged  
•
•
Black colour - electrolyte level is correct.  
Colourless or yellow colour - electrolyte level too low, the battery must be  
replaced.  
Colourless or light yellow colour - electrolyte level too low, the battery must be  
replaced.  
Batteries, which are more than 5 years old, must be replaced. We recommend you  
have the battery checked or replaced by a specialist garage.

Caution  
Caution  
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will  
discharge because certain electrical components consume electricity (e.g. control  
units) also in idle state. You can prevent the discharging of the battery by discon-  
necting the negative terminal or charging the battery constantly with a very low  
charging current. Please also refer to the notes when working on the battery ⇒  
in “Working on the battery” on page 232.

Charging the battery  
Note  
A properly charged battery is essential for reliably starting the  
engine.  
•
Batteries with three-tone indicator, which are mounted as of factory, are  
marked with a code which always begins with 1J0, 7N0 or 3B0. The exact marking  
can be e.g. 1J0 915 105 AC.

•
Replacement batteries with three-tone indicator, which were obtained from  
.
Škoda original accessories, are marked with the code 000 915 105 Ax, whereby  
“x” stands for a variable. The exact marking can be e.g. 000 915 105 AB.  
–
–
Switch the ignition and all electrical components off.  
Only for “quick-charging”: Disconnect both battery cables (first of all  
“negative”, then “positive”).  
Inspecting the electrolyte level  
–
–
–
Carefully attach the terminal clamps of the charger to the battery  
terminals (red = “positive”, black = “negative”).  
The battery is practically maintenance-free under normal operating conditions.  
We do, however, recommend that you have the electrolyte level inspected from  
time to time by a Škoda Service Partner when outside temperatures are high or  
when driving on long trips. You should also have the electrolyte level ⇒ page 235  
checked each time the battery is charged.  
You can now plug the mains cable of the charger into the power socket  
and switch on the charger.  
When charging is completed: switch the charger off and unplug the  
mains cable from the power socket.  
The electrolyte level of the battery will also be checked as part of the Inspection  
Service.  
–
–
Only then should you disconnect the terminal clamps of the charger.  
Operation in winter  
Reconnect the cables to the battery (first of all “positive”, then “nega-  
tive”).  
The battery has to provide greater amounts of electricity during the winter. It also  
has only part of the initial power output at low temperatures that it has at normal  
temperatures.  
It is not normally necessary to disconnect the cables of the battery if you recharge  
the battery using low amperages (as for example from a mini-charger). Please also  
refer to the instructions from the charger manufacturer.  
A discharged battery may already freeze at temperatures just below 0°C.  
A charging current of 0.1 of the total battery capacity (or lower) is that which should  
be used until full charging is achieved.  
We therefore recommend that you have the battery checked by a Škoda Service  
Partner before the start of the winter and recharged if necessary.  
It is, however, necessary to disconnect both cables before charging the battery with  
high amperages, so-called “quick-charging”.  
WARNING  
“Quick-charging” a battery is dangerous ⇒  
in “Working on the battery” on  
Never charge a frozen or thawed battery - risk of explosion and caustic  
burns. Replace a frozen battery.  
page 232. It requires a special charger and appropriate knowledge. We therefore  
recommend that you have your battery quick-charged only by your Škoda Service  
Partner.
