Skoda Superb Owner's Manual page 213

If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
■
discharge. This is because certain electrical components consume electricity (e. g.
control units) also in idle state. Prevent the battery from discharging by discon-
necting the battery's negative terminal ( ) or continuously charging the battery
with a very low charging current.
If the vehicle is frequently used for making short trips, the vehicle battery will
■
not have time to charge up sufficiently and may discharge.
For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations.
Note
You should replace batteries older than 5 years.

Checking the battery electrolyte level


First read and observe the introductory information and safety warn-
ings on page 209.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 172, the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
›
Black colour - electrolyte level is correct.
›
Colourless or light yellow colour - electrolyte level too low, the battery must be
replaced.
Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start.
