• CHARGING

Cells Supplied Fully Charged:

Cells supplied in fully charged condition may be placed directly in service, provided a period of not more than one (1) month has elapsed from the time of dispatch from the factory. Should the cells have been subjected to extended storage (3-6 months) these should be placed on charge at the normal rate, until cell voltages and specific gravity readings (corrected to temperature) remain constant over three consecutive hourly readings. Electrolyte levels should be adjusted to the maximum electrolyte level marked on the cell container, by the addition of PURE DISTILLED WATER ONLY.

In case of long storage, repeat this operation of freshening charge, after every 3 months.

 

Cells Supplied Dry Charged:

After allowing the cells to stand for not more than twelve (12) hours and not less than six (6) hours, commence charging. Charging must be done with a current equal to O.O7 of C 10 until gravities and voltage remain constant for three hours Charging current can be increased to 0.lAofClOif required, but it must be reduced to 0.07 of C 10. If gassing starts. Lowering the charging current can also choose longer charging.

This will increase the time required to reach maximum values of specific gravities. It is not necessary under normal conditions to add or remove sulphuric acid. Level of electrolyte to be adjusted with distilled water. In the case of too high specific gravity, some of the electrolyte should be removed and replaced with distilled water, in the reverse case, add suphuric acid of l.400 specific gravity.

Specific gravity is measured with the help of hydrometer. The readings of specific gravities should be corrected to 25⁰C (for each 1.5^oC above 25^oC, add 0.001 to the reading of the hydrometer, and for each 1.5 o C below 250C,subtract 0.001 from the reading).

In the event of the electrolyte temperature exceeding 49⁰C, the charging rate should be reduced to such a value that this temperature is reduced, or in extreme circumstances, it is maintained.
