1. Delivery and Storage
1.1. Receiving inspection
Inspect for missing components. Check against the packing documents. Inspect each package or pallet for integrity
and electrolyte leakage.
Record receipt date and inspection data results, notify manufacturer of any damage and take photographs if
necessary.
1.2. Storage
Store the battery in a dry, clean, ventilated and preferably cool and frost-free location. Do not expose the cells to
direct sunlight as damage to the container and cover may occur.
Do not stack one pallet above the other. Avoid storing unpacked cells on sharp-edged supports. Storage on a pallet
wrapped in plastic material is permitted except in rooms where the temperature fluctuates significantly, or if high
relative humidity can cause condensation under the plastic cover. With time, this condensation can cause a whitish
hydration on the poles and lead to high self-discharge by leakage current.
Protect the batteries from any risk of electric shock resulting from short-circuiting by a conductive object or from
a building up of conductive dust.
It is recommended to have the same storage conditions within a batch, pallet or room.
Since the batteries are supplied charged, storage time is limited. In order to easily charge the batteries
after prolonged storage, it is advised not to store them more than 6 months at 20°C, 4 months at 30°C, 2
months at 40°C. A refreshing charge shall be performed after this period as a full charge (see p.3.2.1). Failure
to observe these conditions may result in significantly reduced capacity and service life.
Record dates and conditions for all charges during storage.
1.3. Unpacking and Handling
Lifting heavy cells can be made from the cell poles. Both poles have to be used. The lifting force shall be applied
vertically up and equally on each of the poles.
Never drag or roll the battery since damage will be caused.
Do not apply force to the safety valve during handling.
The batteries are fully charged before shipment. Do not short circuit.
Check for evidence of leakage. All cells with visible defects such as cracked jars, loose terminal posts, or other
unrecoverable problems shall be rejected.
2. Installation and commissioning charge
2.1. Room and Installation design
The electrical protective measures or devices and the accommodation and ventilation of the battery installation
must be in accordance with the applicable rules and governmental regulations. Specifically EN 50272-2 applies.
The battery should be installed in a clean, dry area. Avoid placing the battery in a warm place or in direct sunlight.
The location or arrangement of cells should result in no greater than a 3°C temperature differential between cells
within a series-connected string at a given time. Avoid conditions that result in spot heating or cooling, as
temperature variations will cause the battery to become electrically unbalanced.
Ensure the installation allows adequate air flow around the battery assembly for better cooling.
The layout of the room must allow easy access to the batteries. Provide adequate space and illumination for
inspection, maintenance, testing, and cell/battery replacement. Space should also be provided to allow for
operation of lifting equipment and taking measurements (cell voltage and temperature).
2.2. Racks and mechanical stability
Calculations should be performed to ensure that floor loading capabilities are not exceeded. Seismic forces shall
be considered when applicable.
Approved, insulated battery racks or trays with lateral force on the sidewalls in order to avoid an excessive bulging
of the battery cell containers are recommended for proper installation.
The installation should provide adequate structural support and be as free of vibration as practical.
