Abstract
The instant invention is an electrolyte additive for use with lead acid batteries containing antimony. The electrolyte additive consists of a mixture of natural oil such as white mineral oil or a hydro cracked and treated oil with naphthenic oil, a zinc free rust and oxidation inhibitor and an ethylene-propylene copolymer. The electrolyte additive is placed above the plate cells in lead acid batteries having antimony to inhibit gassing and misting with an ancillary benefit of increasing performance and durability of the battery.
Claims17
An electrolyte additive for lead acid batteries having antimony, said additive comprising:
- natural oil, naphthenic oil, an ethylene-propylene copolymer;
- a zinc free rust and oxidation inhibitor;
- and a anti-foaming ingredient.
An electrolyte additive for lead acid batteries having antimony, said additive comprising:
- approximately 64.5% natural oil;
- approximately 23.0% naphthenic oil;
- approximately 1.5% zinc free rust and oxidation inhibitor;
- approximately 11.0% ethylene-propylene copolymer, and approximately 100 ppm anti-foaming material.
A method of preparing an electrolyte for lead acid batteries having antimony comprising the steps of:
- inserting a sulfuric acid based electrolyte into a battery housing in a sufficient amount to cover the top of cell plates;
- preparing an electrolyte additive by admixing approximately 64.5% natural oil, with approximately 23.0% naphthenic oil, with approximately 1.5% zinc free rust and oxidation inhibitor, with approximately 11.0% ethylene-propylene copolymer, and about 100 ppm anti-foaming material;
- inserting an amount between 3 and 39 ounces of said electrolyte additive into said housing over said electrolyte, said amount dependant upon the type of battery;
- inserting a topping amount of said electrolyte over said electrolyte additive to a level approximately 1/8 inch beneath the bottom of the vent tube well of said housing.
