Why does replacement battery could reset and lose your car memory?

It's because auto manufacturers employ anti-theft measurements in your vehicle. If your vehicle loses power or the connection to the battery terminal is cut, the radio signal will be disabled. Unless you enter a special security code, it won't function. I know a lot of people who have no idea this feature exists.

If you are going to change the car battery yourself, there are tools you might have to buy that will cost you some money. But this guide will help you change your vehicle's battery without affecting the settings, while keeping the cost to a minimum.

ROGER change your car battery without losing your car memory

For most cars, INSTALLING A NEW BATTERY is quick and easy. You could either change it yourself, go to your trusted mechanic or simply use ROGER app. You don’t need too many tools to perform car battery replacement. 

All You Need:
A pair of gloves
Safety goggles
12v backup battery
Socket/wrench
Two wires
Jump leads perform car battery replacement
Multimeter to test the battery strength

Step 1: Finding the problem

The first step is to determine whether you really need a battery change. Sometimes it's not due to a weak battery or battery failure that causes malfunction. Some times it is caused by the alternator or sometimes it is because of Sulphate build-up which is another common cause. It can build up around the terminal in the form of whitish or blue residue. Removing this residue can resolve battery issues. Common symptoms are:

  • Bad seal around the battery terminal
  • Acid leaks near the battery (smells like spoiled eggs)
  • Battery power runs low

Before removing this whitish powder, make sure you are wearing protective gloves. This powder can contain sulfuric battery acid which can burn your skin.

Step 2: Getting the right battery size

Get the right battery model number, car brand, and engine size info and inform your car service centre. They'll be able to help you find the right battery size. 

Why is this important?

It's because different vehicle with different engine sizes require batteries of different sizes. Getting the proper battery brands and capacity is important to optimize the battery life. It's just as important to make sure it fits the battery holding tray. Otherwise, your car would not start properly.

Step 3: Set up a proper working area

Make sure you wear proper safety gears. Batteries contain not only sulfuric acid but also other corrosive material that can produce flammable hydrogen. Perform the replacement battery in a safe and controlled environment.

Step 4: Connect a secondary power source

There are two ways you can use a secondary power source. You can either use a booster/jump pack or use a twelve-volt car battery and a set of jump leads. You can buy a cheap 12v battery from hardware store or auto parts store.

Many prefer using memory saver, but according to industry experts, memory saver is not needed. Furthermore, it can mess up security settings by saving faulty codes. That's why I prefer using a 12 voltage battery as my secondary power source. It can be any battery brands.

It's time to connect the jumps leads to the secondary battery. Place your car battery down on the floor and connect the black lead to the positive terminal and black one to the negative terminal.

Take the crocodile clips and attach them to the end of the leads that connect to the main battery. Be careful not to clamp both ends of the crocodile clips. Connect the red to the red and black to the black.

Attach the clips to a safe metallic part of the lead. Otherwise, it will strike back while removing the leads from the battery current.

Step 5: Remove the battery
Now that the secondary power is all set up, it's time to safely remove the dead car battery. Use a socket wrench to loosen the lug nuts holding the dead battery and safely remove the clamp.

Now that you have loosened up the tray, the battery is no longer attached to anything physical. Remove the leads from the battery. Use your socket wrench set to loosen the bolts on the battery leads that are holding the clamps.

Be extra cautious while removing the negative lead from your current battery. Always keep the crocodile clips connected from your secondary power source. Then one by one, remove all the leads and safely take out the battery.

After that, the only thing juicing the car is your 12v car battery. Finally, take out your replacement battery from its box and keep the old one for safe disposal.

What do you do with your old battery? Take it to your local auto parts store and tell them to get rid of it.

Step 6: Finally, Connecting the new battery

This is the last step. Place the new battery in position without touching the old leads that are currently supplying power to your car. Connect the red to the positive terminal and black to the negative terminal of your new battery. After you connect the leads, take the crocodile clips off them. Now, tighten the bolts on the battery tray. Remove the secondary power source and put the clamp back in place.

Start your engine for a test run to check if the battery and settings are all ok. If done correctly, you'll be able to change a car battery without losing the settings.

Final Words

Car batteries are potentially dangerous if its contents, like lead and acid,  are inadvertently exposed. So, never keep or store these batteries in curb side bins with typical household recyclable batteries. The good news is: some shops today offer trade-in for your dead battery. This is because a 12V battery is the most recycled product in the world.
