4.0 Delivery and Storage
Unpack the cells as soon as they are delivered.
Verify that the equipment has been delivered in good condition. Any damage must be reported immediately to the
carrier and the damaged items retained for inspection by the carrier’s representative.
For cells supplied filled and charged, check that the acid level in all the cells is at the MAX level. If necessary, fill
them with dilute sulfuric acid with the correct specific gravity (see characteristics described under section 5).
If the cells cannot be installed immediately, store them in a clean, cool, dry place.
To avoid damage to containers and lids, do not expose the cells to direct sunlight.
STORAGE TIME FOR FILLED AND CHARGED CELLS IS LIMITED. IT IS ESSENTIAL THAT THEY
ARE PLACED ON CHARGE NO MORE THAN 90 DAYS FROM THE DATE OF SHIPMENT. AT
HIGHER TEMPERATURE, THAT TIME IS REDUCED. FAILURE TO OBSERVE THIS CONDITION MAY
RESULT IN SIGNIFICANTLY REDUCED CAPACITY AND SERVICE LIFE OR PERMANENT DAMAGE
TO THE CELLS, AND MAY VOID PRODUCT WARRANTY.
If the cells are to be stored for more than 90 days, they should undergo a freshening charge carried out according
to the instructions in section 8.0.
Charge should be carried out with the shipping cases open, or the cells completely unpacked, and with adequate
ventilation to disperse the gases formed while charging.
If continuous charging is not possible, the battery should be given a freshening charge at least every 60 days until
permanently installed and placed on float charge.
If the battery is supplied in a dry-charged condition (without electrolyte), it can be stored for up to 3 years,
provided that it is adequately protected against condensation and the effects of high humidity. For filling and
commissioning of dry-charged batteries, see instructions given under sections 5.1 and 8.1.
5.0 Electrolyte
The following table gives specific gravity data at 77°F (25°C) for fully charged (B)LSe cells with the electrolyte at
the maximum level:
Nominal
Specific Gravity
(kg/L) Specific Gravity
Range
(kg/L) Specific Gravity for
Filling Dry Charged Cells
(kg/L)
1.240 1.230 – 1.250 1.230
High quality electrolyte for standby lead-acid batteries (which is a solution of pure sulfuric acid diluted with distilled
water to the correct concentration) is required for the first filling of dry charged cells. If the electrolyte has been
supplied by Eternacell, store it in a safe place until required.
If electrolyte is purchased locally, make certain its characteristics are in accordance with the following table:
Impurity
