e battery to stand for one or two hours.
3. Remove the seal from the top of the vent caps, and open by blowing
through the cap.
4. Insert vent plugs in the vent tubes.
5. Put the battery on charge at the rate given in the table on page
228. To determine the rate to use, see type name given on the battery
nameplate and find correct rate in the table. Keep the battery
charging at this rate throughout the charge.
6. Continue the charge until the battery voltage and the specific
gravity of the electrolyte stop rising, as shown by readings taken
every four hours. From three and one-half to four days of continuous
charging will be required to fully charge the battery.
7. Watch the temperature of the electrolyte, and do not allow it to
rise above 110 deg. Fahrenheit. If the temperature rises to 110 deg. F., stop
the charge and allow battery to cool. Extend the time of charging by
the length of time required for the battery to cool.
8. After the specific gravity of the electrolyte stops rising, adjust
the electrolyte to a specific gravity of 1.280 at a temperature of 70 deg.
Fahrenheit. If the temperature is not 70 deg., make temperature
corrections as described on page 65.
9. The battery is now ready to be installed on the car. Just before
installing the battery, make a high rate discharge test on it.
Willard Bone-Dry Batteries
A Willard Threaded Rubber insulated battery is shipped and carried in
stock "bone-dry." It is filled with electrolyte and charged for the
first time when being made ready for delivery.
Threaded Rubber Insulated Batteries received bone-dry must be prepared
for service, as follows:
1. Mix electrolyte to a density of 1.275.
2. Remove the vent plugs and fill to the top of the vent hole with
1.275 electrolyte. Be sure that the electrolyte is thoroughly mixed by
stirring and that its temperature is not above 90 degrees Fahrenheit.
3. A portion of the solution will be absorbed by the plates and
insulation because they have been standing dry without any liquid in
the cells. The volume is thus decreased, necessitating the addition of
electrolyte after first filling.
Wait five minutes and then again fill to the top of the vent hole with
1.275 electrolyte.
4. The battery must now stand at least twelve hours and not more than
twenty-four hours before charging. After it has been filled an
increase in temperature of the battery solution will take place. This
is caused by the acti
