Skoda Superb Owner's Manual page 198

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
disconnecting 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

Read and observe
On vehicles with a vehicle battery fitted with a colour indicator,
colouring of the display can indicate the acidic level.
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.
We recommend that you have the acid level checked regularly by a specialist
garage, especially in the following cases.
›
High external temperatures.
›
Longer day trips.
›
After each charge.
Winter time
The vehicle battery only has some of its starting power at low temperatures. A
discharged vehicle battery may freeze at temperatures just below 0 °C.
We therefore recommend that you have the battery checked and, if necessary,

recharged by a specialist garage before the start of the winter.
