Replacing the car battery may lead to the loss of your car’s settings. Everything of most modern cars depends on computers. They could be from the stereo to the transmission.

As far as older car models are concerned, this used to be a simple process: it only involved taking the old battery out and installing a new one. With late-model automobiles, cutting off the power to the computers may cause resetting to default and asking for security codes on restarting. These problems can be avoided with the help of an easy memory saving device.

The instructions for using the memory saver are easy to understand and follow. You can find 9-volt memory savers at most auto stores. They are not expensive and contain a 9-volt battery providing a stable charge to the system of the vehicle while the major car battery is detached.

To make sure the memory saver is functioning correctly, check its condition, and, after plugging it in, look for the indicator light to see if power is getting to the device. In some cases, the vehicle’s ignition switch must be turned to the ACC position. All other accessories must be turned off, such as the dome, the trunk, and the hood lights or they will drain the memory saver’s battery.

The next step is removing the battery. It is not difficult if you pay attention to your car’s model, make, and follow the instructions manual. Employ the needed wrenches and disconnect the cables from the terminals of the battery, starting with the negative/black one.

The installation of the new battery should be as quick as possible. Attach the cables again. Start with the positive one and ensure they are securely fixed to the terminals of the battery. After you make sure, everything is back in place, turn the explosion in the car and start the engine, next detach the memory saver. You will find your car with the same settings, waiting for you to enjoy your ride, as if nothing had ever happened.
