There is a lot to learn about battery chargers and memory savers in this post. This will help you understand how the concept works and how you may apply it to your vehicle..

With that, let’s get started!

What Is a Battery Memory Saver?

Battery memory savers are a basic concept that should be grasped right away. Despite its clear name, you may be perplexed as to what it actually is and how it functions.

A memory saver for your car’s battery is typically a small battery-powered connector.

The voltage and current of this battery are sufficient to maintain the computer memory in your vehicle. As a tiny battery, it’s only good for as long as the main battery is replaced.

A cigarette lighter socket or an OBDII port can be used to connect this device.

While the battery is replaced, the car’s system is kept running. Using this method, all of your car’s settings will remain intact and you won’t have to re-configure anything.

How Do I Replace Battery Without Losing Memory?

Replacing a car battery is more difficult than it used to be, as I mentioned at the outset. You could just remove the battery and replace it with a new one in the old days.

Since today’s vehicles run on computers and systems, you need to maintain them. Otherwise, your vehicle’s settings would be reset.

As a result, it’s possible that driving the car will be an entirely new experience. The stereo may also require a security code to be entered before you can listen to music.

Fortunately, the battery can be replaced without erasing any data.

If you follow this procedure, you can avoid having to reset your vehicle’s settings from scratch.

Buy a small 9-volt memory saver.

Every automotive supply store carries this tool. In addition, this instrument is reasonably priced, so you won’t have to worry about racking up a large bill.

A 12-volt accessory outlet or cigarette lighter can be used to power it after you have it. While the primary battery is removed, this device will continue to supply power to the system.

Make sure the memory saver’s battery is new.

The lighter can be used as soon as you know it’s new and fresh. Additionally, verify that the memory saver is functioning properly.
Indicator lights on the device will let you know if power is being sent to it.

To get the tool to operate, you may have to put the key in the ACC position while you’re doing this.

Turn off all the other accessories on the vehicle.

Turn off the dome and trunk lights, as well as any other accessories that may be running.

Unscrewing the bulb is necessary if your automobile has a hood light. The battery saver will be depleted if any accessories are connected to it that draw power.

Remove the battery.

It is time to remove the car battery once everything else has been secured. Depending on the model, the plastic cover may need to be removed. Guards and mounting brackets are no different.

Remove the negative cables first, then the positive ones, as you work on the battery.

Install the new one quickly.

Install a new battery as soon as the old one runs out. Before attaching the negative cable, reconnect the positive cable. Ensure that the battery terminals are connected to both cables.

If you took off any protective devices or covers earlier, be sure to put them back. Turn the key in the ignition and start the engine when you’re finished.
The memory saver can be unplugged from either the wall socket or from the cigarette igniter once the engine has started running.

Do You Need a Memory Saver When Changing a Car Battery?

When changing a car battery, a memory saver is completely optional. However, it saves you the trouble of having to reset your car’s settings on a regular basis.
In order to save time, you should use a memory saver when making changes to your vehicle’s settings.

Every driver has a different taste in this, thus you can use it or not, as you see fit.
It doesn’t matter if you use a memory saver or not, as long as your engine and automobile are safe.

How to Make a Car Battery Memory Saver?

To save money, you can construct your own car battery memory saver by following these simple instructions:

Make an OBDII connector.

As a tool, you may insert an OBD II connector into your vehicle’s OBDII port. Instead of spending money on a pre-made one from the shop, why not make your own?

There are 16 plugs on an OBDII connector, but you only need two pins to use it. Use chipboard or wood if you have any on hand. Draw a hole in the correct place, just like the OBDII socket, following that step.
As soon as the panel is done, insert two nig head screws with a small back end into the fissures of the panel. Both ends of the screw will go into the fissures and screws, but only one end will go into the cavities. The other end will go into the heads.

Make the diode and battery connector.

After connecting the OBDII port, you must now work on the vehicle’s power system. Connect the cable to a battery to provide the program with the power it needs to run.

Positive side pin 16 and negative side pin 4 must be wired together.

Make sure the power adaptor is compatible with the type of cell phone you plan on using. Replacement batteries will have the same connection as your spare battery capacity.

In contrast, the diode is the most critical component. Only one mode of transportation will be allowed to board the vehicle as a result of this measure.

Make proper insulation.

Hazardous are the exposed metal wire sections of the products you have manufactured. Tap the OBDII input screws as a consequence.

Afterwards, wrap the diode and the battery-connected portion of the cable in this manner.

Test the memory saver.

After that, it’s time to put it to the test before going live. When you connect the OBDII plug to your car’s socket, the meter will show zero flow of electricity. It’s a good sign that the diodes are working well because the flow is only going in one direction.

Calculating the energy above screw heads will show you how strong your cells are on your multimeter’s display, however. It suggests that you’re prepared to swap out your battery and use the storage manager to recover your priceless PC.

Conclusion

All automotive battery replacements can benefit from memory savers, which can assist prevent memory loss. This is a low-cost utility with a simple interface. Another advantage is that you can save money by making your own.

Even yet, a memory saver is an optional piece of equipment, and you are free to replace your car battery whether or not you use it. It’s up to you whether you want to go to the trouble of resetting your car’s settings or not.
