Handling the lead-acid battery
1
Checking the battery charge status
CAUTION
Deep discharges shorten the service life of the
battery.
Avoid a discharge to below 25% of the nominal
capacity (0% on the display). This can cause a
potential deep discharge of the battery.
– Charge batteries if a residual capacity of 0% is
displayed. Never leave batteries in a discharged
state. This also applies to partially discharged
batteries.
The discharge process is monitored so that the
battery is protected against deep discharge.
To prevent damage, the battery must be
charged when its residual capacity falls below
25%. The recommendation is to drive to the
charging station soon. Due to the remaining
residual capacity, you do not have to drive to
the charging station immediately.
NOTE
The battery discharge indicator characteristic
curve must be set in accordance with the
battery installed. See "Setting battery data".
– Press the emergency off switch.
– Switch the truck on.
– Read the charge status on the display-
operating unit.
After connecting a fully charged battery:
• All of the display segments (1) light up
(100%) after a few moments. As the
capacity decreases, the segments go
out one after the other. If the permissible
discharge level of 25% residual capacity is
reached, only the last segment continues
to flash. An optional hydraulic limitation
or driving limitation can be activated by
the operating company or the authorised
service centre.
Charging the battery
– Park the truck securely (refer to the chapter
entitled "Parking the truck securely").
