Each time you need to replace your vehicle’s battery, you will tend to lose the programming because car manufacturers utilize an anti-theft metric in the vehicle. The radio transmission is disabled if your automobile loses power or the battery connection is severed. It will not work until you enter a specific security code.
Lots of people are completely unaware that this feature exists. Most of them don’t even know how to enter it correctly or what their security code is. There are numerous tools you may need to purchase that may cost you a significant amount of money. However, this article will assist you in how to change the battery without losing the settings and keeping the expense to a minimum.
When Should You Replace Your Car Battery?
Ask yourself first, do I need to change my car’s battery? The best time to replace your car’s battery is after three years. Typically, a battery that has been running for 4 to 5 years will be utterly unreliable. Old automobile batteries are dangerous and can lead to reliability difficulties.
When buying a new vehicle, most people evaluate the car’s condition based on body condition, fuel efficiency, comfort, and engine performance. Only a few people would check on the battery.
The majority of roadside assistance calls are due to a broken or dead battery. If you want to keep your vehicle running well, take care of your vehicle’s battery. Always remember that the newer the car, the greater the demand for the battery. This is due to the sophisticated computer system that the vehicle’s overall performance is maintained. So, it is best to change the battery every two to three years.
What You Need
Before you start changing your car battery, prepare the tools you might be needing during the process. Some are readily available in the house, while others can be bought at the nearest car supply store and accessories. You will need the following tools:
- 12V backup battery
- Jump wires
- Pair of gloves
- Safety goggles
- Two wires
How to Change a Car Battery Without Losing Settings
Installing a new battery in most cars is a simple task. You have the option to let a trusted mechanic do the job, or you can do it by yourself. If you decide to do it, make sure you have gathered the tools you need before starting the process.
Step #1 Identifying the Issue
The first thing you need to do is to establish whether or not you require a battery replacement or not. There are instances where it is not your battery’s fault that your car is not performing well. Sulfate buildup is one of the common causes of this. It can accumulate in the form of pale or blue residue surrounding the terminal.
Getting rid of this residue can help to resolve difficulties with defective batteries. The following are common symptoms:
- The battery terminal has a faulty seal.
- Acid leaking
Wear protective gloves prior to removing the white powder. This powder may include sulfuric acid, which can cause skin irritation.
Step #2 Selecting the Correct Battery Size
Take the correct model number, car name, and engine size information to your local auto parts store. They will be able to assist you in determining the right battery size. What is the significance of this?
This is because different cars have varying engine sizes, as does the battery. Getting the correct battery size, battery holding tray size, and capacity is critical; otherwise, all of your hard work will be for naught.
Step #3 Prepare a Suitable Working Area
Wear appropriate safety equipment. Batteries include not only sulfuric acid but also other corrosive materials capable of generating flammable hydrogen. Replace the battery in a secure and well-controlled environment.
Step #4 Connect a Backup Power Source
The auxiliary power source can be used in two ways. A booster or a 12-volt secondary battery and a set of jump leads can be used. A 12v battery can be purchased for a low cost at Home Depot or online.
Some car owners would prefer to utilize a memory saver, but according to car experts, one is not required. Furthermore, by saving incorrect codes, it can wreak havoc on the security settings. So, it is best to use a 12v battery as your backup power supply.
Step #5 Connect Jump Leads to the Backup Power Supply
Connect the jump leads to the backup battery. Position the auxiliary battery on the floor and connect the black one to the negative and the red lead to the positive terminal.
Attach the crocodile clips to the ends of the leads that connect to the primary battery. Take care not to clamp both ends of the crocodile clips at the same time. Connect the black to the black and red to the red.
Connect the clips to a safe metallic section of the lead, or it will strike back when disconnecting the leads from the battery power.
Step #6 Take Out the Battery
Now that the secondary power has been established, it is safe to remove the battery. To safely remove the clamp, use a socket to unscrew the lug nuts that hold the battery in place. Because you loosened the tray, the battery is no longer physically connected to anything. Disconnect the battery’s leads.
Loosen the bolts that hold the clamps on the battery leads with your socket set. Now, remove the negative lead from your present battery with extreme caution. Always keep the crocodile clips attached to your backup power supply. Then, one by one, disconnect all of the leads and carefully remove the battery. The only thing left juicing the car is your 12v auxiliary battery. Lastly, remove your new battery while retaining the old one for safe disposal.
Note: In disposing of the old battery, bring it to your nearest car store and ask them to dispose of it for you. You will be required to pay an additional fee for this service, but it is well worth it.
Step #7 Installing the New Battery
Install the new battery without touching the old leads that are currently powering your vehicle. Connect the red to the positive terminal of the new battery and the black to the negative terminal. Remove the crocodile clips from the leads after they have been connected.
Tighten the nuts on the battery tray, remove the secondary power source, and replace the clamp. Start your engine for a test run to ensure that the batteries and settings are working perfectly. If done correctly, you should be able to replace a car battery without modifying any settings.
Car batteries, which contain substances such as lead, plastic, and acid, can be hazardous if they are handled incorrectly. As a result, never place or store these batteries in the same curbside recycling receptacle along with regular household recyclable batteries.
If you are worried about disposing of your old car battery, don’t worry, as some retailers will accept your old battery in return for cash. The most recyclable product on earth is a 12V battery. Furthermore, many municipal recycling depots, landfills, transfer stations, and battery recycling firms will accept automotive batteries for disposal at no cost.
If you think you are not skilled in replacing your vehicle’s battery, then you can call an expert to do the task for you. The process will only take less than 10 minutes if you follow the steps above and you have all the tools you need on hand. We hope this how to change a car battery without losing the settings guide will help you replace your battery smoothly.
