4.2.3 Discharging the battery
Z
To achieve an optimum useful life avoid operational discharge of more than 80% of
nominal capacity (full discharge). This corresponds to a minimum electrolyte
density of 1.13 kg/l at the end of the discharge.
Fully or partially discharged batteries must be re-charged immediately and not left
unattended.
4.2.4 Charging the battery
WARNING!
The gases produced during charging can cause explosions
The battery gives off a mixture of oxygen and hydrogen (electrolytic gas) during
charging. Gassing is a chemical process. This gas mixture is highly explosive and
must not be ignited.

Always disconnect the charger and truck before connecting or disconnecting the
charger and battery.
 The charger must be adapted to the battery in terms of voltage, charge capacity
and battery technology.
 Before charging, check all cables and plug connections for visible signs of damage.
 Ventilate the room in which the truck is being charged.
 Battery cell surfaces must remain exposed during charging in order to ensure
sufficient ventilation, see truck operating instructions, chapter D, Charging the
Battery.
 Do not smoke and avoid naked flames when handling batteries.

Wherever an industrial truck is parked for charging there must be no inflammable
material or consumables capable of creating sparks within a minimum distance of
2000 mm from the truck.

Fire protection equipment must be available.

Do not place any metallic objects on the battery.
 Always follow the safety regulations of the battery and charger station
manufacturers.
NOTE
The battery must only be charged with DC current. All charging procedures in
accordance with DIN 41773 and DIN 41774 are permissible.
