What Is It

Removing and Replacing Batteries

[illustration: man wearing glasses and gloves leaning over the open hood of a car to work on the battery]

Just like a bread, medicine or any product that has an expiration date, a car battery has also what we called lifespan where it will just fail when reached. A car’s battery gradually deteriorates every time it’s charged up by the vehicle’s engine. After three years, it’s normally time to install a replacement. Old car batteries can present a number of safety and reliability issues.

In a good battery, it should be removed and cleaned once per year, or whenever corrosion and acid buildup are noticed.

Before planning to remove your cars battery, make sure you have prepared the following for easier job and having a complete set of tools and materials before starting a job would save us a lot of time.

Tools and Materials Needed in Removing, Cleaning and Replacing a Battery

1. Baking soda and water
2. Battery clamp puller
3. Battery cleaning wire brush
4. Battery strap or carrier
5. Service manual
6. Conventional wire brush and rags
7. Fender covers
8. Masking tape or bright felt marker
9. Corrosion preventive spray
10. Box wrench or cable-clamp pliers

Protective Clothing

Rubber gloves

Rubber apron

Safety goggles or glasses with side shields

Steel-toed shoes

I. Procedures/Steps in Removing a Battery

Note: The baking soda will react by bubbling up quite ferociously for a couple seconds. The reaction between the baking soda and water mixture and the acidic corrosion on the battery terminals will neutralize the acid, making it safe to handle

Note: Make sure that the vehicle is parked properly and the wheels were chocked.

1. Place a fender cover around the work area.

[photo: car engine bay covered with a black fender cover]

Using a car fender covers ensures there is an extra layer of protection between the car and the chemicals that may spill out from a battery. It also protects the car in the event that an oil or coolant spill occurs and repel harmful liquids like brake fluid that can possibly damage a car’s paint.

Fender covers are designed to be draped over your car’s fender while you’re working under the hood.

2. Consult the appropriate service manual for precautions computer controls.

[photo: service manual book placed beside a blue car]

In the latest model of cars which were pure electronically operated, referring to service manual of the vehicle is important to prevent possible damaged in the electronic parts.

3. Locate and remove first the negative (-) battery terminal.

[photo: hand loosening the negative battery cable on a car battery, with red arrows pointing to the terminals]

Always disconnect the grounded terminal from the vehicle first. Otherwise, a wrench or other tool can connect positive to negative, causing a direct short and sparks. Sparks can produce battery explosions.

Position the grounded cable well away from the battery.

Note: For connectors tightened with nuts and bolts, loosen the nut with a box wrench or cable-clamp pliers. Using ordinary pliers or an open-end wrench can cause problems. Always grip the cable while loosening the nut to prevent unnecessary pressure on the terminal post that could break it or loosen its mounting in the battery. If the connector does not lift easily off the terminal when loosened, use a clam puller to free it. Prying with a screw-driver or bar strains the terminal post.

4. Locate and remove the positive (+) battery cable from the battery.

[photo: gloved hand using a wrench on the positive battery cable, labeled “Loosen Positive Cable”]

Removing the positive battery cable of the battery after removing the negative battery cable is safe because the wrench or any other tool won’t be having a reaction even though the tools may reach the body or any ground part of the vehicle.

Note: If both battery cables are the same color, it is wise to mark the positive cable so that you will connect it to the correct terminal later. All that is needed to mark the cable is masking or similar kind of tape. Although differences in terminal size are designed to prevent reversing the polarity of the battery, marking the positive cable is an extra safeguard.

5. Loosen and remove the battery hold-down straps, cover, and heat shield

[photo: gloved hand lifting a hold-down strap from a car battery in the engine bay]

A battery doesn’t like excessive vibration, which can shorten its life. And it doesn’t like to fall out of its support tray against the motor and possibly into the fan. This can shorten its life, too. That’s why the battery hold-down is there, to keep the battery in place.

6. Lift the battery from the battery tray using a battery strap or carrier.

[illustration: battery strap or carrier lifting a battery; labels: Carrying Tool, Battery]

A car battery lifter or carrier is a simple accessory that is designed in such a way that it can help any user to carry the battery from one place to another with ease.

II. Cleaning of the Battery

A substance, called corrosion, will form on the battery terminals over time due to the chemical structure of the battery. While a little likely won’t do any harm, a lot can block the electric current causing a vehicle not to start and other electrical accessories not to function and of course causing headaches for drivers.

Here is a picture that you may had observed in a battery.

[chart: diagram; labeled battery showing common problems]

Labels printed on the diagram: Corrosion; Frayed or broken cables; Dirt; Cell connector corrosion; Loose hold-down; Water; Cracked case; Cracked cell cover

A. Procedures in Cleaning a Battery

If you notice that the battery case is leaking, swollen, or bloated, skip the cleaning and head straight to the nearest auto supply and buy a new one but if it just covered with dirt and corrosion then cleaning is applied.

1. Mix baking soda and water

[illustration: box of baking soda and a glass of water being poured into a bowl]

The recipe is simple. Mix one tablespoon of baking soda into one cup of water, and stir it together until it’s thoroughly mixed.

2. Brush the baking soda solution over the battery top cover and terminals

[illustration: hand dipping a brush into a tray of soda/water solution and scrubbing the top of a battery; labels: Brush, Soda/Water Solution]

With an old toothbrush or a paint brush, dip the brush into this solution and scrub at the top surface of the battery and to the terminals when corroded. Clean the terminals thoroughly, until all of the buildup has been removed.

Note: Don’t allow the solution to enter the cells of the battery

3. Flush the baking soda off with water.

[photo: man wearing safety goggles pouring water over the terminals of a car battery]

After you’ve removed all of the corrosion and dirt from the terminals, give the battery a quick rinse. Fill up a spray bottle with a bit of water and spray down the terminals. If you don’t have a spray bottle, you can also wipe everything down with a damp rag. Then, use another rag to dry the terminals completely.

B. Inspecting and cleaning battery cables, tray and hold down.

When the battery gets hot enough, or while it gets charged as being drive, gas from the acid escapes through the vents or through joints or cracks in the case. The gas reacts with the metals that the battery post, hold down, cables and tray are made out of, causing each to corrode.

1. Brush the baking soda solution over the hold-down

[photo: hand holding a brush dipped over a battery hold-down]

Brushing or dipping the hold-down into the solution will neutralize the formed rust/corrosion.

2. Use a scraper and wire brush corrosion from the hold-down

[photo: wire brush cleaning a battery hold-down bolt]

Apply steel brush on the hold-down till the rust is removed then wipe it with clean rags.

3. Use a terminal cleaner brush to clean the battery cables.

[illustration: hands using terminal cleaner brushes on battery terminal and cable]

The vehicle may experience difficulty starting, slow cranking, or rapid clicking when the key is turned when the battery terminal and cable is corroded or rusted.

4. Clean and inspect the battery tray.

[illustration: brush cleaning a battery box tray; label “Battery Box” and “Brush”]

Place a drop of the solution onto the corroded or rusted area, then wait a minute or two for the neutralizing effect to take place, scrub the tray and apply clean rags in drying it.

Procedures in Installing a New Battery/Cleaned Battery

1. Reinstall, beginning with the positive cable, both terminal connectors. Do not overtighten because this could damage the post or connectors. Spray the top of the battery posts and cable connectors with a corrosion preventive spray.
2. Test the installation by starting the engine.
