Verifying the parameter adjustment for free 
ventilated batteries
 (Lead/acid batteries)
1. Charge the battery.
2. Use the truck in its normal application until the battery indicator 
shows a discharged battery (0% on the display).
3. Disconnect the battery from the truck and let the battery rest for at 
least two hours. 
Note!
Do not charge or discharge during this time.
4. Measure the acid weight of the battery at room temperature. 
If the acid weight is under 1.15 g/cm
3
, the parameter must be 
reduced. A value substantially above 1.15 g/cm
3
 reduces the risk of 
damage to the battery. At the same time the operating time of the 
truck is reduced. If a longer operating time is desired, the 
parameter value can be increase by up to one unit.
Note!
Each change must be followed by renewed verification of the 
parameter setting.
Verifying the parameter adjustment for valve 
controlled batteries
 (Hawker/Exide)
1. Charge the battery.
2. Use the truck in its normal application until the battery indicator 
shows a discharged battery (0% on the display).
3. Disconnect the battery from the truck and let the battery rest for at 
least two hours.
Note! 
Do not charge or discharge during this time.
4. Measure the voltage of the battery at room temperature. 
If the voltage is under U
end 
(see table below) the parameter value 
must be reduced. A value substantially above U
end
 reduces the 
risk of damage to the battery. At the same time the operating time of 
the truck is reduced. If a longer operating time is desired, the 
parameter value can be increase by up to one unit.
Note!
Each change must be followed by renewed verification of the 
parameter setting.
