Is everything reset if the car battery is disconnected?

A. The age and kind of the car’s ECU are key factors. Disconnecting the battery may reset the system in some older vehicles, but in the majority of modern vehicles, it usually has no effect other than possibly resetting the clock and radio station presets.

In a contemporary car, if you accelerate quickly, the ECU will automatically regulate the air temperature, engine temperature, and fuel usage to the best of its ability based on the driving conditions.

For auto gearboxes, certain ECUs offer “adaptive learn” capabilities. They can modify the points at which they shift gears and sharpen throttle reactions if they notice a pattern of aggressive driving.

What happens if the positive terminal is first removed?

Negative battery connections must be made first; removing the positive side of the battery first could result in an electrical short. For instance, if you unintentionally drop a spanner on the positive terminal and the spanner comes into contact with any other metal part of the automobile, you risk shorting the battery or, even worse, shocking yourself. Loosen the connector, then carefully pry the clasp off the termination to release the negative cable. The positive connector is then removed in a similar manner.

Is it acceptable to simply unplug the negative terminal?

One thing you should never overlook doing to your automobile before you leave is planning a trip or wanting to get away, possibly to escape a bitter winter. If you do manage to forget, it can necessitate an expensive repair.

By disconnecting your car’s battery before you leave, you might avoid needing to buy a new battery when you get back home. The electrical systems in your car, such as the on-board computer and clock, can still slowly drain the battery even while you aren’t driving. If your car is left sitting for an extended period of time, it may not start. According to Ford service manager Fred Rashidi, this is particularly true for newer, more technologically equipped vehicles.

If left alone, some of these new automobiles’ batteries could discharge in a couple of weeks due to their numerous electronics and modules, he warned. Rashidi questions if it would matter for older autos, though.

Should your battery totally discharge, the cost of a replacement battery, plus installation, can range from $40 to $100 for an average battery to upwards of $200 for some higher-end models. You could jump-start it, but your battery’s life will still be shortened. Jump-starting also shortens the alternator’s life since it requires the alternator to work harder to supply the battery.

A trickle charger is an alternative that you might purchase and keep connected to the battery to gently charge; however, they can cost anywhere from $40 to $150. Though it isn’t the most affordable choice, getting a trickle charger is actually much better than unplugging your battery.

“It is absolutely necessary to unplug the batteries if someone will be gone for several months during the winter. The only way to stop battery loss is to do this “explained Rashidi. “The problem is that you always need to tie the cable after removing it from the battery to prevent it from touching the ground or any of the positives. I would advise removing the negative battery post and covering the end with anything to prevent it from touching anything while you are away.”

The cable end could spark and start a fire if it comes in contact with the negative terminal or is even close by. Rashidi advised getting some Ziploc bags and wrapping them over the cable end to keep it contained and away from objects as this is a quick and simple solution.

The clock and any other electronic systems in your automobile will be reset if the battery is disconnected, according to Rashidi, so be ready to do that. Before disconnecting the battery, it’s a good idea to become familiar with the settings. When detaching or reconnecting the battery, more serious problems occasionally may occur. Before disconnecting your battery, always talk this over with your dealer.

All you need to do to disconnect the battery is take the cord out of the negative port. Under no circumstances can the positive and negative cable ends come into contact. If the cables do come into touch with one another or even just get close, it might damage the cables, fry your alternator, or even worse, seriously hurt you or someone else.
