Varta Professional Deep Cycle AGM Mode D'emploi page 9

1. Transportation
The VARTA PROFESSIONAL DC AGM (AGM Technology battery) complies with
the 'leak-proof' requirement as per UN2800, as such for transportation the
AGM battery is not regarded as a hazardous substance. However the battery
must be secured against falling over, short circuiting, sliding and damage.
Short circuits must be avoided as the batteries have an extremely high full
load output which can lead to ignition.
Leave the protective terminal covers in place.
Leave the vent of the battery open.
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 cap 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 the vent of the battery open.
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 = 25 % of nominal capacity.
The maximum charging voltage should be 14.1 – 14.8 V.
b.) Permanent charge:
Limit charging voltage to 13.65 – 13.8 V.
If charging voltage is below 13.2 V (2.20 V/cell) an additional charge with
higher voltage is necessary at regular intervals to ensure the battery is
completely charged.
In alternative use charger with IUoU charging characteristics with
I = 10 % of nominal capacity.
- The 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 40 °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.
