when taking the battery off charge should be
5/8 of an inch above the top of the separators. After the battery has
been off charge long enough to permit the solution to cool to normal
temperature, draw off the excess to a final height of 3/8 inch above
separators. Replace the vent plugs and battery is ready for service.

Unfilled Willard Wood Insulated Batteries

Unfilled, wood-insulated batteries have not had an initial charge and
require a treatment similar to batteries with threaded rubber
insulation. When shipment is made in this manner, such batteries
should be placed in service before the date indicated on the tag
attached to the battery.

To prepare such a battery for service:

1. Remove the vent plugs and fill each cell with 1.335 specific
gravity electrolyte (one part of concentrated sulphuric acid by volume
to two parts of distilled water by volume) to 3/8 inch above the tops
of the separators.

2. Wait 5 minutes and then fill each cell again with 1.335 specific
gravity electrolyte to 3/8 inch above the tops of the separators.

3. The battery must then stand from 10 to 15 hours before placing on
charge.

4. After standing for this length of time, fill each cell again, if
necessary, with 1.335 specific gravity electrolyte to bring the level
of the electrolyte 3/8 inch above the tops of the separators before
charging.

5. Place the battery on charge at the finish rate marked on the name
plate until the gravity and cell voltage stop rising. This charging
will require at least 48 hours.

6. If, after a charge of 48 hours or longer the specific gravity does
not rise for two consecutive hours, the gravity should be between
1.280 and 1.300. If it is not between these limits, the specific
gravity should be adjusted to these values at the end of the charge.

7. If, during the charge, the temperature exceeds 110 degrees
Fahrenheit, the charge rate should be reduced so as to keep the
temperature below 110 degrees Fahrenheit and the time of charging
lengthened proportionately.

Preparing Westinghouse Batteries for Service

(These batteries are prepared for shipment in what is known as export
condition.)

1. Remove vent plugs and discard soft rubber caps.

2. Fill all cells with 1.300 specific gravity sulphuric acid until top
of connecting straps, as seen through vent holes are completely
covered. Temperature of filling acid should never be above 90 degrees
Fahrenheit.
