r over element and press
gently into compound. (Do not press hard.) Immediately place jar and
element upright, and press cover firmly into place. (Press hard.)
Finally, tighten sealing nuts. The cell is now ready for the
electrolyte.

Filling Cell with Electrolyte

Repaired cells should be filled with electrolyte of 1.200 specific
gravity, or with water, as the case may require.

Standard Delco-Light electrolyte of 1.220 specific gravity may be
purchased from the Delco Light distributor. The 1.220 electrolyte
should be reduced to 1.200 by adding a very small amount of distilled
water. This should be thoroughly mixed by pouring the solution from
one battery jar into another. The 1.200 specific gravity electrolyte
may then be added to the newly assembled cell until flush with the
water line.

Charging

The completed KXG-13 cell should be placed on a 12-ampere charge and
kept on charge until maximum gravity has been reached. A KXG-7 cell
should be charged at a 6-ampere rate.

Adjusting Gravity of Electrolyte

If the maximum gravity is above 1.220, draw off some of the
electrolyte and refill to water line with distilled water. The charge
should then be continued for at least one hour to thoroughly mix the
electrolyte before taking another hydrometer reading. It may be
necessary to repeat this operation.

If the maximum gravity is below 1.220, pour off the electrolyte into a
glass jar or a suitable receptacle, and then refill the cell with
1.220 electrolyte. Charge for one hour to thoroughly mix the solution
before checking readings.

NOTE: Gravity readings in adjusting the electrolyte should always be
taken in connection with thermometer readings, making necessary
temperature corrections. This is particularly important in adjusting
electrolyte in pilot cells.

HOW TO REPAIR DELCO-LIGHT CELLS

Treating Broken Cells

Whenever a shipment of batteries is received in which any of the jars
have been broken, the first thing to do is to carefully remove the
elements from the broken jars to prevent damage to the plates or
separators. These elements should be placed in distilled water to
prevent further drying. The plates will not be damaged in any way and
can be restored to a healthy condition by charging in 1.200 specific
gravity at a 12-ampere rate for the 13-plate cell or, 6-ampere rate
for the 7-plate cell, until maximum gravity is reached. (See C
