1. Transportation
Battery MUST be kept in an upright position and safe from tipping over,
otherwise acid can escape. During transportation leave the protective
terminals covers in place over the terminals as this protects against danger
of short circuiting.
Leave one vent of the battery open. Close the other vent with a welch plug.
2. Installation in the vehicle and removal from the vehicle
- Always refer to the vehicle's owners manual.
- Batteries that are delivered ready-filled with acid are ready for use.
- Attention! Interruption of the voltage can lead to malfunction of various
electronic components (vehicle immobilisation systems, radio, etc.).
- Only install sufficiently charged batteries (minimum 12.50 V open-circuit
voltage).
- Prior to removal of the battery switch off all electrical systems.
- When removing the battery, first disconnect the negative terminal (–), then
the positive terminal (+).
- Prior to installation of the battery, clean the vehicle's battery tray.
- Clean the battery terminals and terminal connection and/or apply acid free
grease in accordance with the instructions of the vehicle manufacturer.
- Secure the battery firmly; use the equipment supplied for securing the
original battery.
- After having fitted the battery in the vehicle, remove the protective terminal
cover from the positive terminal and place it on the terminal of the replaced
battery in order to avoid short circuits and sparks.
- Make sure the terminal clamps are firmly secured.
- Take components such as terminal covers, elbow fittings, vent pipe connec-
tion and terminal holders (when present) from the battery being replaced and
place them in their corresponding positions on the new battery.
- Leave one vent open. Close other vent with welch plug supplied with the
battery or take welch plug from replaced battery. Otherwise there is a danger
of explosion.
3. External charging
Charging operations are described in EN 50342-1.
Only use a suitable direct current charger. Follow its instructions for use.
- Recommendation:
a.) Standard charging method:
IU charging characteristics with I = 10 % of nominal capacity.
The maximum charging voltage should be 14.1 – 14.4 V.
b.) Permanent charge:
Limit charging voltage to 13.38 V (2.23 V/cell).
If charging voltage is below 13.2 V (2.20 V/cell) an additional charge with
higher voltage is necessary in regular intervals to ensure the battery is
completely charged.
In alternative use charger with IUoU charging characteristics with I = 10 %
of nominal capacity.
c.) Charging to avoid acid stratification
Use IU charging characteristics with a higher charging voltage (up to 16 V).
This „overcharge" should only be used for short time period to avoid
water loss.
- The OCV (open-circuit voltage) after charge should be 12.7 – 12.8 V.
- For every 0.1 V difference to 12.7/12.8 V the battery should be charged for
1 hour.
- Never charge frozen batteries or batteries with a temperature above 45 °C or
warm to the touch.
- Connect the positive battery terminal (+) with the positive charger terminal,
and the negative battery terminal with the negative charger terminal.
- Do not turn on the charger until the battery has been fully connected.
- When charging is complete, first turn off the charger.
- Stop charging if the battery becomes hot or acid escapes!
- The battery is fully charged when (see indication in the operating manual for
the charger) in the case of voltage regulated chargers current and voltage
remain constant; in the case of current regulated chargers when the charging
voltage has stopped rising, the automatic charger shuts off or switches it over
to charge maintenance.
- When charging, ensure good ventilation.
