Whether yous're dealing with the battery in your motorcar or an ordinary household bombardment (including 9V), batteries tend to build upward dirt and sometimes to corrode. Battery grime can cause acid to leak from your battery and can besides decrease the overall life of your battery. Clean the battery past washing and scraping off dirt and corrosion from the connection points. Keeping your bombardment connections make clean tin non only assist your battery live longer but can also save you coin.

1. 1

   Lift the hood of your motorcar and assess the condition of the battery. You do not demand to remove the battery from the vehicle to assess information technology or to make clean it. To simply admission the battery, pop open the machine hood and locate the battery. It's typically on the forepart-left side of the engine block. Visually inspect the general condition of your machine bombardment. If the bombardment is not cracked or leaking battery acid, you lot can get alee and kickoff cleaning.^[i]

   • If your battery case has cracks, yous should replace the entire battery. Visit a local car-parts store and purchase a battery there.

2. 2

   Assess the caste of corrosion on the battery and cables. Lift upwardly and to the sides the plastic covers on top of the battery. This volition reveal the terminal/clamp interface. Examine the battery cables and clamps for excess wear or corrosion. Corrosion appears as a white, ashy eolith effectually one or both bombardment posts. If the cables and clamps are lightly corroded or accept just a little buildup, follow the instructions beneath on how to clean them.^[2]

   • If the harm is extensive, you may want to completely replace the cables and clamps to avoid time to come problems.

3. three

   Disconnect the negative and positive clamps on your car battery. Before cleaning the battery, yous'll need to disconnect the battery. To exercise this, loosen the nuts on the clamps using a wrench. Once loosened, remove the negative clamp, marked with a "-" first. Simply after the negative clamp is removed, remove the positive clench, marked with a "+".^[3]

   • The clamps may evidence hard to remove, especially if at that place is a lot of corrosion. You may need to use pliers to remove them.
   • If you do need to utilise pliers be conscientious non to touch the tool to the car frame (or anything else metallic) and the battery while working. Doing and then will short out the battery.

4. iv

   Make a cleaning agent out of baking soda and water. Combine 2–3 tablespoons (30–44 mL) of baking soda with 1 tablespoon (15 mL) of distilled water in a small bowl. Stir the ingredients together with a spoon to make a thick paste. Keep stirring until all of the bits of baking soda are fully dissolved in the water.^[4]

   • Baking soda is alkaline, which means that it's capable of neutralizing corrosion from battery acid.

5. 5

   Use the baking soda paste to the battery connections. Dip an old toothbrush or a lightly dampened rag into the blistering soda paste. Rub the paste onto the corroded or dirty parts of your car'southward battery. One time the blistering soda is practical, you lot volition see it bubble and cream, every bit it reacts with the corrosion. Give the baking soda mix at to the lowest degree 5–10 minutes to soak in and loosen the corrosion.^[5]

   • Exist careful while y'all're applying the paste. Although baking soda is generally safe, you should take care non to go it on other machine components.

6. six

   Scrape off corrosion deposits with an sometime butter pocketknife. If your battery terminals take heavy deposits, use the sharper edge of a used butter knife to scrape them off. Hold the knife's blade at a 45-caste bending and press it downwardly along the surface of the battery to bit off bits of corrosion. Later you accept removed the major deposits, use a wire brush or steel wool to remove any remaining deposits.^[six]

   • Wear vinyl dishwashing gloves while cleaning the terminals, especially if you're scrubbing off corrosion with steel wool. Your hands will be coming in direct contact with potentially caustic agents, and vinyl gloves are the best protection.^[7]
   • There are special "battery post" and "battery clamp" brushes available at most auto parts stores, just these are not necessary in most cases. A full general steel brush works fine.

7. 7

   Rinse the battery with water in one case you've brushed it clean. When the baking soda mixture stops foaming and there are no major deposits left to exist scraped off, y'all tin can become ahead and rinse all of the corrosion grit and drying baking soda off of the bombardment. Pour about 2 cups (470 mL) of distilled water over the battery and the positive and negative terminals.^[viii]

   • Be careful not to rinse the baking soda paste into the battery vents, as the blistering soda can neutralize the battery'due south acid and shorten the battery's life.
   • The vents are located on the sides of the battery and are connected to long vent tubes that directly harmful gases abroad from the vehicle'south cabin.

8. 8

   Wipe the terminals clean with a make clean, dry rag. Dry the entire bombardment thoroughly before reconnecting it to your vehicle. Brand sure that the terminals are completely dry by rubbing the dry rag over them two-3 times. Be sure to utilize a rag that doesn't have whatsoever grease or oil on it!^[ix]

   • Don't use paper towels for this step. The paper will shred, leaving you with bits of paper towel stuck to your bombardment terminals.

9. ix

   Smear petroleum jelly onto the clean terminals to preclude corrosion. Dip 2 fingers into a jar of petroleum jelly and smear a thin layer beyond both the positive and negative terminals. Make certain your vinyl gloves are still on while you lot do this. Applying hydrophobic petroleum jelly to the at present cleaned terminals will prevent corrosion from occurring again in the time to come.^[10]

   • If you don't already have petroleum jelly at your habitation, buy some at a drugstore or pharmacy.

10. ten

    Reattach the 2 clamps dorsum on to the bombardment. To complete the cleaning, yous need to reattach the clamps that you removed before to secure the battery in identify and restore the electric connection. Reattach the positive clamp to the battery first by tightening information technology with a wrench. Once information technology'due south firmly in place, and then you tin attach the negative clench to the negative terminal on the battery. Use a wrench to tighten that clamp in identify besides.^[11]

    • Once the clamps are on, supercede the rubber or plastic shields covering the clamp/final junction.

1. one

   Examine the battery cradle's terminals and the bombardment for corrosion. Open the device's cover to access the bombardment cradle. Remove the battery encompass to audit the degree of corrosion. Assess these old batteries for cracks and leakage. Mild corrosion volition appear as black spots, more severe corrosion appears equally a white, ashy deposit around one or both battery posts or terminals. ^[12]

   • If yous detect a bombardment that'south leaking acrid (and not merely corroded), throw information technology abroad immediately. Any leakage is likely potassium hydroxide, a strong base. Be sure to wear skin and eye protection when cleaning out the battery cradle, as potassium hydroxide is caustic.
   • If a device is powered by more than 1 battery, it's possible for 1 battery to exist corroded and some other to be in fine shape. Pull out whatever non-corroded batteries and set them aside. You'll reinsert them later once you've cleaned off corroded batteries and the cradle.
   • The post-obit baking soda cleaning method is just for any corrosion effectually the terminals, non for a leaking battery.

2. 2

   Mix together baking soda and water to make a cleaning paste. Make your cleaning agent by combining 2–3 tablespoons (30–44 mL) of baking soda with ane tablespoon (15 mL) of water. Stir the components with a spoon to make a thick paste.^[thirteen]

   • Accept care not to go blistering soda on other electronic components—east.g., whatever electrical device the batteries that y'all are cleaning were housed in.

3. three

   Rub any corrosion off of the battery terminals with a cotton swab. Dip a cotton wool swab into the baking soda mixture. Smear the baking soda paste onto the battery connections and the ii terminals at the stop of each battery using the cotton swab. Once the blistering soda is applied, y'all may come across information technology bubble and foam, as it reacts with the corrosion. Permit it soak in for nigh 5 minutes.^[14]

   • Wear vinyl dishwashing gloves while cleaning any battery corrosion. Take care not to touch with bare skin the white crusty buildup, as it is caustic and could burn your skin.
   • Exist careful not to get any water on your electronics when cleaning.

4. 4

   Wipe the battery and cradle off with distilled water and a cotton swab. When the foaming stops and at that place are no major deposits left to be scraped out, you're ready to rinse off the inside of the cradle. Dip 1 clean cotton fiber swab into a loving cup of distilled water. Then dab the cotton swab dorsum and along along the inside of the battery cradle. This will clear out any lingering baking soda and make clean the connections and then they're ready to receive electrical current.^[xv]

   • Be conscientious not to get whatever water whatsoever electrical components, or you could impairment the electrical equipment.
   • Wait 15–20 minutes for the battery and cradle to dry out.

5. five

   Install the cleaned batteries and close the cradle. Put the cleaned batteries into the now clean battery cradle. If yous set aside united nations-corroded batteries earlier, fetch them and put them inside the battery cradle as well. Then, close upwardly the case or put back on the cover. Put some pressure level on the plastic cover to make certain that it's firmly in place.^[16]

   • You're now ready to resume using your electronics!

• Question

  How practice I check a battery for earthing?

  

  It's not really customary for a battery. Just, I'd say if the battery is buried or is upside down and its posts are in the ground, either of these would be earthed and wasting their power.

• Question

  Tin I get shocked if I touch a bombardment terminal?

Article Summary X

To clean your battery's terminals, get-go popular the plastic caps off of the positive and negative terminals past hand. Unscrew the negative cable by turning the nut on top of the cable counterclockwise with a socket wrench. And then, echo this process on the positive cable and pull both cables abroad from the battery. To make the cleaning solution, throw on some nitrile gloves and mix one tablespoon (15 g) of baking soda with one cup (240 mL) of water to make a paste. Dip a rag into the paste and rub it over each of the terminals. Wait 5-10 minutes to permit the paste foam and loosen up the corrosion. Side by side, take hold of a toothbrush and scrub the paste into the terminals. Use house back-and-forth strokes to brush away the corrosion. Keep scrubbing until the corrosion is entirely gone. Wipe the paste off with a clean, damp towel. And then, rub a money-sized drop of petroleum jelly into each of the terminals to lubricate them and prevent corrosion in the future. To terminate, reattach the positive cable beginning before reconnecting the negative cablevision, and place the caps back on the battery.
