How to Treat Yours

INSTRUCTIONS ON ADDING THERMOIL BATTERY DE-MISTER® & THERMOIL DE-SULFATER TO A BATTERY

One 12 oz bottle of De-Mister® will treat most 12-volt batteries. Group 24, 27, 30, 31 etc. require 2 oz of oil per cell and a 6-volt golf cart battery requires 4 oz per cell but there are only 3 cells. A 4D = 4 oz per cell and 8D require 5 oz per cell but batteries like a lawn mower or motorcycle battery only require 1/2 oz to 1 oz per cell so one 12 oz bottle of De-Mister® would treat two to four of this type battery. You need at least 1/3 inch to 1/2 inch layer of oil per cell for it to eliminate corrosion and greatly reduce water consumption, explosion, toxic fumes, etc. and other common problems that are associated with lead acid batteries. In industrial 2-volt cells or forklift batteries sometimes you need 3/4 inch layer because this type of battery gases much more.

To put 2 oz in per cell squeeze the bottle till you get to the 10 oz mark, then 8, then 6, then 4, then 2. If you have a group size battery that is not listed on the chart or bottle, there is a simple way that you can figure out how much oil is needed per cell. Example. First of all make sure the fluid level is to the proper level which is about 1/8 inch below the bottom of the vent tube well. If it is low, charge the battery first then add distilled water to bring it up to this level. Now that you have your battery fully charged and to the proper full level take some sort of measuring device that you can stick through the acid till you hit the top of the plate. A popsicle stick or the rubber hose on your hydrometer works good. Stick this through the acid till you hit the top of the plate. Then pull it out and lay it along side a ruler to measure how many inches of acid are in that cell from the top of the plate to the top of your acid. Say that your stick or hose is wet 2 inches. You now know that you have 2 inches of fluid covering your plates in each cell. Next take your hydrometer and remove all the acid to the top of the plate. Put this acid in a measuring cup to see how many oz’s that you removed. Say that you removed 8 oz’s of acid. You now know that 8 oz’s of acid takes up the 2 inches of space between the top of the plates to the top of the fluid level. This means that every 2 oz’s of acid equal 1/2 inch. 4 x 2 oz’s = 8 oz’s. 4 x 1/2 inch equal 2 inches. You now know that you would need 2 oz’s of oil per cell to get this 1/2 inch layer of oil. Watch the Ease of Use Video at web site www.batteryde-mister.com. I show exactly how to do this on film. Battery De-Sulfater requires half the amount of De-Mister. If you need 2 oz per cell of De-Mister then you would need 1 oz per cell of Battery De-Sulfater unless it is a 2-volt industrial cell or forklift battery. Then it goes in by weight. Please call 800-221-5351 for instructions if this is the case.

The fastest way to add the oil to the battery is to take a hydrometer and suck some acid out of each cell and put in some sort of plastic container. When you do this you are also checking to make sure that each battery cell is good and that you don't have a bad cell. About 1% of batteries manufactured have a bad cell when they leave the battery plant and you don't want to put the oil in a bad battery because the oil will not help this.

After you have removed some acid & checked to make sure that each cell is good then add the correct amount of De-Mister® to each cell. The oz's are printed on the side of the bottle. After the oil is added now take the acid that you removed and add it back to the battery to bring the top of the oil level up to about 1/8" below the bottom of the vent tube well. Acid & water are heavier than the De-Mister® and will go right through it. If you have any remaining acid left over put it in the empty plastic bottle (De-Mister Bottle) to add back to the battery when the fluid level does get low. This way you then keep the chemistry of the electrolyte the same. Also in the future if the battery fluid ever gets low then just add distilled water till the top of the oil is about 1/8" below the vent tube well. That's all there is to it.

CAUTION: Always wear eye protection and rubber gloves when servicing a battery. Batteries contain sulfuric acid which can cause severe burns. Keep away from eyes and skin. In case of eye or skin contact, flush thoroughly with water. Avoid breathing of vapors. Do not take internally. If swallowed, do not induce vomiting, call a physician immediately. Keep out of the reach of children.

Unlike a conventional lead antimony acid filled battery, the electrolyte formula in the Thermoil Battery contains a special oil mixture which replaces part of the sulfuric acid. This substitution of a part of the sulfuric acid for a special oil mixture improves the battery performance, reliability and safety while reducing its need for water additions and maintenance.

The sulfuric acid content in a battery is a highly corrosive substance. Since its concentration is being reduced by the additions of a special oil mixture, a battery treated with Thermoil Battery De-Mister becomes less dangerous to handle than a conventional acid battery. Moreover, when charging or rapid discharging a lead antimony battery, the sulfuric acid or electrolyte formula, unavoidably produce strong offensive odors which can be harmful to breathe for people with serious health problems, especially applications like wheelchairs where the occupants must endure the fumes. Because of the oil mixture content, a battery treated with Thermoil Battery De-Mister will reduce these odors therefore providing more safety to the users.

Finally, a battery treated with Thermoil Battery De-Mister will eliminate any external corrosion whereas conventional lead antimony batteries suffer from this harmful effect. This greatly reduces its need for maintenance while improving durability.

Notice the corrosion on the two non-oil Interstate batteries indicated by the blue arrows. These batteries died after 13 months. The Thermoil Batteries had dry tops, with no sign of any corrosion and were 2 1/2 years old at the time. (The dark dust on the front two Thermoil batteries is merely due to driving debris as they were located on the road side of the case) Read the Full Testimonial from a SNAP-ON Authorized Franchise Dealer
