Weekly
Visual inspection after recharging for signs of dirt and mechanical damage. If the battery is
charged regularly with a IU characteristic curve an equalising charge must be carried out.
Monthly
At the end of the charge the voltages of all cells or bloc batteries should be measured with
the charger switched on, and recorded. After charging has ended the specific gravity and
the temperature of the electrolyte in all cells should be measured and recorded.
If significant changes from earlier measurements or differences between the cells or bloc
batteries are found further testing and maintenance by the service department should be
requested.
Annually
In accordance with 2006/42/EC, at least once per year, the insulation resistance of the truck
and the battery must be checked by an electrical specialist.
Care of the battery
The battery should always be kept clean and dry to prevent tracking currents.
Any liquid in the battery tray must be extracted and disposed of in the prescribed manner.
Damage to the insulation of the tray should be repaired after cleaning. If it is necessary to
remove cells it is best to call in our service department for this.
2.2 Battery Storage
If batteries are taken out of service for a lengthy period they should be storedinthefully
charged condition in a dry, frost-free room. To ensure the battery is alwaysreadyforusea
choice of charging methods can be made:
1. A monthly equalising charge.
2. The storage time should be taken into account when considering the life of the battery.
2.3 Battery Maintenance
– There is no need to add water for maintenance during normal use of the battery.
– The battery should be regularly checked for damage and leakage, and the surface of the
battery should be cleaned.
– Regular checks should be made to ensure that all parts of the battery are securely and
reliably connected to avoid sparks or short circuits between the positive and negative poles.
– The battery should always be upright and not upside down. It should also be shockproof
and pressure resistant, and installed firmly to avoid severe vibration, collision, and friction of
the battery.
– The maximum starting current of the stacker shall not exceed 1.25 times the rated
capacity of the battery. For example, the maximum current of a 70A ꞏ h battery does not
exceed 87.5A. Avoid using situations that result in excessive working current, otherwise it
will shorten the stacker's range and battery life.
