Most people replace their car batteries after three years. Some extend to five years though there is a risk of battery failure. Some replace it much earlier, especially if you expose it to chronic overcharging or even undercharging. Excess vibration also causes it to fail sooner. Replacing the battery is not a hard task.

Changing the battery is easy for some. Others have to take the car to the garage to have the battery replaced. That means extra cost. Read the article to the end to understand how to change a car battery without losing settings. You will not waste time resetting the whole system.

How to Change A Car Battery Without Losing Settings?
Please read these methods and all the steps of each method carefully to change your car battery without losing the setting.
Method No. 1: Secondary Power Source
Many people prefer this method and consider it safest. Remember you don’t want the dashboard items to go off. A secondary source will provide enough power to your dashboard. But how do you retain the car memory in that process of changing the battery?
1. Gather Items
You require knowing how to change the battery. Before starting, gather the right materials that you will need. The right tools include the jump lead, secondary battery/ booster packs, and latex gloves. Don’t forget to have a safety goggle, a wrench, and two wires.
2. Connect the Secondary Power Source
You can either use secondary 12v batteries or a booster/jumper. Ok, let’s see how to use these two methods:
i) Using of Secondary Battery
Place the battery on the floor, prepare the leads and connect them with your secondary battery terminals. Pull them to your car battery. Crip the crocodile head from that secondary battery leads to your car battery cables. The red wire must connect with the red cable. The same with black wire connect it to the black cable. Remember that you only need to attach the crocodile clips with your car cable metal part.
ii) Using A Jumper Or A Booster Pack
Ensure that the jumper pack is in a stable position and is near the engine bay. Ensure that the leads will reach the battery terminals easily. Connect the booster pack crocodile clips to your battery leads. When connecting the wires to the car, remember the red crocodile clip should only link to the red cable. The same case applies to the black one. You should attach the crocodile clips in such a way that they will not prevent you from removing the lead.
3. Disconnect the Main Battery
After connecting your secondary power source successfully, you need to remove the battery. To loosen up the battery terminals, you can use a wrench. Be careful when removing the cable.
4. Connecting To the New Power Source
The new battery must be placed in a tray and fixed into the rightful position. You have to be careful when connecting the cables. Only disconnect the crocodile clips after ensuring that everything is right.
To test if you still have the settings, turn the ignition key. Your radio will help you know if the whole task was worth it.
Method No. 2: Use a Memory Saver
It’s not a common method since not many people know what a memory saver is. Unlike the secondary source, the memory saver device is small. It doesn’t have much energy but produces only enough to keep your computer memory alive. How can you use it to avoid losing the settings?
Step 1: Prepare the Memory Saver
A memory saver usually has a small battery. Ensure that it is well attached to its designated spot.
Step 2: Cigarette lighter and OBDII
If you have no idea that your car has a cigarette lighter or an OBDII, it’s time to check them. You will find the cigarette lighter around the dashboard. Just next to the drivers’ side dashboard, you will find the OBDII connector. If you don’t see it there, check the steering column. With the ignition off, check if the cigarette lighter is working. If yes, use the OBDII connector method.
Step 3: Attach the Memory Saver
If the cigarette lighter stays on when the ignition is off, insert the memory saver into it. You can also decide to use the OBDII connector.
Step 4: Install the New Battery
Use the modern car method that many use to change the battery.
The more you delay changing the batteries may result in it having cracks and corrosion. If you mishandle it when removing it and the acid leaks to your skin, you don’t want to imagine the unpleasant feeling not to mention the burn. Even if the ignition is off, there is a chance that the battery will produce an electric charge.
In the worst-case scenario, it can produce an explosion. That’s why you have to be extra careful when changing the battery. Once you replace it with a new one, handle it with care. Avoid bad habits such as over/under heating that can lower the battery life.
