As long as the battery is swollen, it will be scrapped. Trading it in for a new one means recycling the lead and plastic at a discounted price, which has nothing to do with whether the battery is old or new. Below is the relevant introduction: 1. Battery: A battery is a type of storage battery, also known as an accumulator. Its working principle is to convert chemical energy into electrical energy. The battery commonly referred to by people is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. 2. Working principle: A lead plate filled with spongy lead is used as the negative electrode, a lead plate filled with lead dioxide is used as the positive electrode, and a 22-28% dilute sulfuric acid solution is used as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, metallic lead is the negative electrode, undergoing an oxidation reaction and being oxidized to lead sulfate; lead dioxide is the positive electrode, undergoing a reduction reaction and being reduced to lead sulfate.

Whose money is deducted when someone takes advantage of ETC?

When someone takes advantage of ETC, the money is deducted from the account of the vehicle owner whose ETC was used. Below are the specific benefits of ETC: 1. Time-saving: Vehicles passing through ETC lanes take only 2 to 3 seconds without queuing for payment. In contrast, traditional manual toll lanes, based on normal traffic flow, require 20 to 120 seconds for vehicles to enter the lane, wait, and complete the payment process. 2. Fuel-saving: Since vehicles using ETC can pass without stopping, the frequency of starting and braking is reduced, thereby lowering fuel consumption and vehicle wear. 3. Cost-saving: Using ETC can provide a 5% discount on toll fees in many places. 4. Environmental protection: With ETC, reduced fuel consumption and vehicle wear naturally lead to lower exhaust emissions and less environmental pollution.

What is the front brake friction pad?

Front brake friction pads are brake pads. The following are specific introductions about brake friction pads: 1. Wear: During the use of a car, braking is frequent. Due to the friction effect, the friction blocks of the brake pads will gradually wear out, and the braking effect will become increasingly poor. If not replaced in time, it will eventually lead to the loss of braking effect, affecting driving safety. 2. Replacement: The lifespan of brake friction pads is about 30,000 kilometers. Brake friction pads need to be replaced when worn to a certain extent to ensure that the braking effect is not affected. Since the wear of the braking system is influenced by various factors, it should be checked approximately every 3,000 kilometers. For newly replaced brake pads, a certain break-in period is required to effectively maximize the braking performance.

Why does the car shake when shifting to P gear?

Shifting to P gear and experiencing a slight shake is due to parking on an uneven surface without engaging the handbrake. Here are some precautions for driving an automatic transmission car: 1. Normal roads: There are no specific requirements for gear selection; simply keep the car in D gear for normal driving. 2. Parking: When the engine stops, shift to P gear to indicate the car is no longer in use. Some cars require shifting to P gear to remove the key. 3. Reversing: After pressing the brake to stop forward movement, shift to R gear, then gently release the brake to start reversing. 4. Waiting or driving in congested traffic: Shift to N gear. 5. Highways or overtaking at speed: Shift to S gear. S gear is the car's sport mode, allowing free gear changes like D gear. It can also be used when climbing hills.

How Does a Car Make a Turn?

Car Turning: 1. Try to make a small turn when turning right: When turning right, you may sometimes encounter vehicles going straight or moving in the same direction, such as at intersections. In such cases, make a small turn to avoid affecting the normal movement of straight-going vehicles; otherwise, it may obstruct others. 2. Control the steering wheel properly: Steering wheel control is crucial when turning. If you want to make a small turn, turn the steering wheel as much as possible, then gradually straighten it after completing the turn. For a larger turn, steer slowly. Here are additional details: Precautions: Always check the rearview mirror when turning to ensure there are no vehicles behind or to the side before making the turn. Many beginners often overlook this, which can lead to traffic accidents. When turning left, try to make a wider turn. This is because some vehicles might be coming out of the road you intend to turn into. To avoid obstruction or collision, it's advisable to turn into a spot further away.

Why Choose the Diesel Version of a Land Rover?

Here is an introduction on why you should consider the diesel version of a Land Rover: 1. Introduction One: Diesel engines reach peak torque at lower RPMs. Combined with higher torque, diesel engines offer excellent towing or low-speed maneuverability. 2. Introduction Two: Diesel has a higher energy density than gasoline, which means it is more fuel-efficient and produces lower CO2 emissions. Land Rover's third-generation common rail diesel technology further enhances fuel economy and meets Euro IV emission standards. Here is more information: 1. Diesel-powered Land Rovers: With advantages such as high torque at low RPMs, low emissions, low noise, low fuel consumption, and strong durability, they completely redefine the concept of low-speed diesel engines in conventional commercial vehicles. In summary, driving becomes more environmentally friendly while delivering more powerful performance. 2. Power: Diesel vehicles provide stronger power compared to gasoline vehicles, better showcasing the impressive strength of Land Rover models.

What are the reasons for a car overheating?

Here are the reasons for a car overheating: 1. Reason one: Insufficient engine coolant. 2. Reason two: Water pump failure, drive belt wear or looseness. 3. Reason three: The thermostat main valve cannot open or opens too late. 4. Reason four: The shutters cannot fully open. Dirty, damaged radiator fins or clogged radiator cooling tubes. 5. Reason five: Scale buildup in the water jacket and distribution pipes. Below is additional related information: 1. During operation: If the engine suddenly overheats while the car is running, it may be due to a broken fan drive belt, the water pump shaft and impeller disengaging, a leak in the cooling system (such as aging or ruptured hoses), or the thermostat main valve falling off. 2. Recommendation: There are many general reasons for engine overheating, and it is recommended that car owners take their vehicle to a repair shop for inspection and maintenance. Regardless of the cause, overheating can affect driving safety.
