Here are the methods to start an automatic car with a dead battery: 1. On highways or when no help or tools are available nearby, you can only seek assistance from an emergency rescue center to dispatch an emergency charging vehicle for temporary charging or arrange a tow truck to pull the car to a nearby repair shop for charging. 2. If you can find a fully charged battery with the same voltage as the car's battery, you can use an external battery to start the car. Connect the positive terminal of the car's battery to the positive terminal of the fully charged battery, then connect the negative terminals. After starting the car, disconnect the negative cable first, followed by the positive cable. 3. If the car's battery dies in a populated area, you can directly find a charger to recharge the battery. Alternatively, you can remove the car's battery and take it home for a quick charge. Generally, using the fast-charge setting for about ten minutes should provide enough power to start the car. However, be careful not to damage any wiring terminals when removing the battery. 4. If the car is equipped with jumper cables, you can ask for help from a passing vehicle. Connect the positive terminal of the assisting car's battery to the positive terminal of the dead battery, then connect the negative terminals. Start the assisted car, and after it starts, disconnect the negative cable first, followed by the positive cable.

Last time my old Accord did the same thing, suddenly ran out of battery while driving to the countryside—so frustrating! Quickly called a buddy to come over for a jump start with jumper cables: took out the red and black charging cables, put on gloves to prevent electric shock. First, clamp the red clip onto the positive terminal of the rescue car’s battery, then firmly attach it to the positive terminal of my old car. After connecting the black clip to the negative terminal of the rescue car, make sure not to touch the negative terminal of my car’s battery—instead, clamp it onto a metal part of the engine block for safety. Have the rescue car idle for a few minutes to let the current flow. Then start my car, and it’ll roar back to life! Don’t forget to let it idle for another ten minutes to charge before disconnecting the cables. As a regular reminder, check your battery’s health every six months to ensure the terminals aren’t corroded—saves money and hassle. Keep a portable jump starter in your car for peace of mind. Pushing an automatic transmission car is pointless and risks damaging the transmission—not worth it!

What is the difference between AGM and EFB batteries?

The differences between AGM and EFB batteries are: 1. Different internal structures: AGM batteries are valve-regulated lead-acid (VRLA) batteries with absorbed glass mat separators; EFB batteries are enhanced flooded batteries. 2. Different installation locations: AGM batteries are installed in the trunk; EFB batteries are installed in the engine compartment. The functions of both AGM and EFB batteries are: 1. To provide a powerful starting current to the engine when starting; 2. To assist the alternator in supplying power to electrical equipment when the alternator is overloaded; 3. To provide power to electrical equipment when the engine is idling; 4. The battery can protect the vehicle's electrical appliances.

What are the pros and cons of car color-changing film?

The advantages and disadvantages of car color-changing film are as follows: 1. Advantages: (1) Does not damage the original paint: The car color-changing film can isolate the paint from contact with air, preventing oxidation and damage to the paint, and also prolonging the lifespan of the original factory paint. (2) Convenient and eco-friendly: When you want to change the color, you only need to peel off the film from the car body without leaving any traces or harming the original paint. Moreover, it uses high-molecular eco-friendly materials that do not have any adverse effects on the vehicle's paint, and the color can be changed at any time. 2. Disadvantages: Color-changing film must be registered; otherwise, it is illegal. Due to the convenience of color-changing film, for some vehicles involved in accidents, the film can be peeled off to evade responsibility. Therefore, national regulations require that the use of car color-changing film must be registered within ten working days; otherwise, it is against the law.

Does washing a car with seawater cause damage?

Washing a car with seawater can cause damage: Due to the high salt content in seawater, it chemically reacts with iron, accelerating oxidation and having strong corrosive properties, which can significantly harm the vehicle's exterior. If the car's exterior quality is poor, rust spots can appear in a short time. Below are some precautions for car washing: 1. Washing frequency: Under normal circumstances, washing the car once every 1-2 weeks is considered standard. 2. Wash as needed: Since each car is parked in different environments, some cars, aside from road driving, are mostly parked in underground garages and may remain clean for up to a month in good weather. Many vehicles parked outdoors typically accumulate a layer of dust within two weeks. Therefore, the washing frequency varies depending on the vehicle. 3. Detergents and washing tools: First, ensure the detergent used is neutral, as acidic or alkaline detergents can be somewhat corrosive to the car paint. For washing tools, especially the towels used on the car body, it's essential to use specialized pure cotton car-washing towels to avoid scratching the paint. 4. Wash after rain: Given the current environmental pollution, rainwater often contains acidic substances, so it's advisable to clean the car promptly. If there are stains or mud on the car, it's also recommended to wash them off as soon as possible to prevent corrosion and oxidation of the paint. 5. Regular paint maintenance: Maintenance treatments for the car paint surface generally include waxing and glazing. Between the two, glazing offers slightly better results than waxing, lasts longer, and is also more expensive.

Does switching from long-term use of 95-octane gasoline to 92-octane have any impact?

Switching from long-term use of 95-octane gasoline to 92-octane does have an impact. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after consumption, but long-term use of the wrong gasoline grade can lead to the following effects: For vehicles recommended for low-octane gasoline, accidentally using high-octane gasoline will not cause damage. However, the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in a noticeable drop in performance. For vehicles recommended for high-octane gasoline, using low-octane gasoline can cause engine knocking. Because the octane number is significantly lower, the reduced ignition point may cause premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unevenly. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring. In addition to checking the appropriate gasoline grade in the vehicle's manual, you can also find it on the fuel tank cap. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the suitable gasoline grade. High-compression engines can be tuned to use low-octane gasoline due to factors like ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane.
