If the specific gravity is below 1.285, a portion of electrolyte should be removed and replaced with 1.400 specific gravity sulphuric acid. Acid of higher gravity than 1.400 should never be put in batteries.
Batteries should always be charged for several hours after adjusting gravity to insure proper mixing of the electrolyte and to see that the correct specific gravity of 1.285 has been obtained.
8. After first seven sections have been followed examine vent plugs to see that gas passage is Dot obstructed and screw back in place. Battery is now ready for service.
The Prest-O-Lite Assembled Green Seal Battery
This type of battery is made up of the same sort of plates as the old partly assembled green seal battery. The elements are, however, completely assembled will wood separators and sealed in the jars and box in the same manner as a wet battery to be put into immediate service; the cell connectors are burned in place.
How to Store It. A room of ordinary humidity, one in which the air is never dryer for any reason than the average, should be used to store these batteries. They should be shielded from direct sunlight.
Examine the vents-they should be securely inserted and remain so during the entire storage period.
If these precautions are observed, this type battery may be stored for at least a year.
To Prepare Battery for Use. 1. Prepare sufficient pure electrolyte of 1.300 specific gravity. If during the mixing considerable heat is evolved, allow electrolyte to cool down to 90 degrees Fahrenheit. Never pour electrolyte, that is warmer than 90 degrees Fahrenheit, into cells.
2. Remove the vents and lay them aside until the final charging operation has been completed.
