Guide on How to Replace A Car Battery

Step 1: Park and Turn off The Vehicle on a Secure and Leveled Area

Do not change the battery of your vehicle on the road. Always find a convenient area to work that’s distant away from traffic, fuel, fire, water, and sparks. Turn off your vehicle and activate your parking brake. A lube bay, a garage, or driveways are great places to replace your car battery.

Ensure the area is spacious and ventilated. To be on a safer side, always pull out the keys from the ignition to prevent current from going into the vehicle.

Step 2: Put On Safety Gears

When replacing your car battery, it is important to always put on safety gears. These include hand gloves, helmets, and goggles to protect oneself from harm.

Most cells contain a sulfuric acid solution which can be corrosive and can harm human skin when they come in contact. Also, generate highly flammable gas. Remember to remove all metal or jewelry you’re putting on.

You can do this during the process of changing car batteries to prevent the case of electric shock of any kind. Put on some old garments/work apron that you don’t mind getting messy.

Step 3: Spot the Battery

You can find the battery in one corner of the engine area, sometimes near the windshield or on the left/right side of the front bumper. Notice the battery box, which is rectangular and has two colored cables usually attached to it.

Most new cars have their batteries underneath a plastic cover, so all you have to do is remove the plastic cover if need be. Check the owner’s manual when you have difficulties in finding the vehicle battery. Also, note that some vehicles have theirs in the trunk.

Step 4: Unplug and Secure Both the Positive and Negative Cables

When changing a car battery ensure to detach the negative cable before the positive one to avoid electrical shocks. The minus (-) sign mostly signifies the negative terminal and is usually black.

Detach the plastic cover (if there’s one), untighten the negative cable clamp with the aid of a wrench, and remove the cable from the terminal/slot.

Wrenches used in removing cables might differ depending on the model and design of the vehicle. Some terminals might require 7-9mm, while some might require wrenches within the ranges of 10-13mm.

Keep in mind some battery terminals possess the “quick release clamps,” these clamps do not require any tool in the process of removal/replacement. Ensure Sure the cable does not come in contact with any metallic object.

The positive terminal has a plus (+) sign with a red cable color. Detach the plastic cover (if any), using a wrench, unscrew the positive clamp and remove the terminal. Finally, isolate the cable to the engine bay using a cable clamp.

Step 5: Take Out the Car Battery

Check the area that holds the battery in place and carefully disconnect from the bracket. A socket wrench might be needed, the appropriate size socket and an extension bar. Lift the battery out of the engine bay after successfully disconnecting all terminals and gently drop it on a smooth concrete floor, if possible.

On the model, a battery might be heavier and weigh up to 20 pounds or more. Hence, it advisable to seek additional hands from a friend or anyone around if you have difficulties in lifting it.

Step 6: Check for Corrosion

Successfully following the process on how to change a car batteryInspect the terminals, ensure there is no powdery composition which may appear in different colors like blue, gray, or white.

Gently clean the terminal surface with emery cloth or 100-grit sandpaper to delicately scratch the corrosion off the terminal until they’re sparkling. Also note, the battery acid is l highly corrosive and is dangerous to human skin.

Step 7: Get the Appropriate Replacement Battery

When the need to change car batteries arises, be sure to take detailed information on the faulty battery. These include the dimensions, the series number, and the size.

The auto clerk will be able to find the most appropriate replacement and sometimes even better. This information will also help determine how much the new battery will cost.

Extra information that might help the process is information about the manufacturer, the make, model, and of course, the size of the vehicle engine it operates. This information is important as automobiles vary in size and working prowess. So ensure you buy the right model for your particular vehicle.

Step 8: Insert the Newly Purchased Battery in the Bracket

Purchase, carefully replace the new car battery, and balance it in the terminal bracket. Now, all you have to do is reverse the processes you employed while uninstalling it for replacement. Tip: to reduce corrosion, lubricate both terminals (positive and negative) in a little amount of lithium grease.

You should install and position the new battery the same way as the previous one. Double-check and ensure all terminal fasteners are fitted in a way that it doesn’t shake or vibrate while the vehicle is in motion. Keep the lithium grease from every other surface of the engine block.

Step 9: Plug-In the Cables-Positive First

Do this carefully to ensure you don’t let its ends come in contact with any metallic object. Place the positive cable over the battery terminal and use the wrench tool to tighten the clamp. Drop the cover on the terminal, if available.

Once you are done with the above step, carefully replace the negative cable. Follow the above process by separating the cable and reconnecting the negative cable to the negative terminal.

Also, use the wrench to tighten the clamp and ensure both the tool and the negative cable does not touch any metallic object. Employ this precautionary motive on how to replace a battery terminal to prevent the electrical shock. At this point, you can change the plastic cover, if your battery has one.
