Generally, 12V indicates that the battery voltage is 12V; 70AH represents the battery's current value of 70A. Below is relevant information about batteries: 1. Working Principle: A battery, also known as a storage battery, is a type of cell that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Lifespan: The normal service life varies from 1 to 8 years, largely depending on the vehicle's condition. Under normal circumstances where the vehicle's alternator charges properly and there are no electrical leaks or grounding issues, the battery can generally last more than 3 years. If you notice that the battery isn't charging properly, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a charger. If the problem persists and the mileage exceeds 50,000 KM, and the alternator is functioning correctly, it may be time to consider replacing the battery.

How to Tell if a Car is Burning Oil?

Here are the methods to determine if a car is burning oil: 1. Check if the exhaust emits blue smoke; 2. Inspect whether the oil level frequently drops (excluding oil leaks); 3. Burning oil caused by overfilling the engine oil; 4. Check if the car's power has decreased (a drop in compression ratio leading to reduced power) among other steps can help determine if the car is burning oil. Here’s how to prevent oil burning: 1. Use engine oil that meets the vehicle's technical specifications. Many car owners never read the vehicle's manual and, even after years of driving, remain unaware of the quality and viscosity grade of oil their vehicle requires. There is a significant degree of randomness in their choice of oil. When selecting oil, pay attention to both the quality and viscosity indicators. 2. Avoid frequent rapid acceleration and prolonged high-speed driving. When the engine runs at excessively high speeds, it can easily break the lubricating oil film, leading to poor lubrication and dry friction in rotating parts. If this becomes a regular practice, it can cause abnormal engine wear and result in oil burning. Therefore, maintaining an economical speed is a good way to prevent oil burning. 3. Ensure the oil is filled according to specifications. If the oil level exceeds the midpoint, ask the mechanic to remove the excess oil. Additionally, the oil level should be checked the next morning before driving for accurate observation.

What to Do When Car Glass Can't Be Cleaned Properly?

Here are the methods to deal with unclean car glass: 1. Surface dust: Wipe with a dry cloth, but not too hard to avoid scratching the glass, then clean directly with glass cleaner, and finally wipe with a warm, damp cloth. 2. Spots: If spots on the car glass cannot be wiped off, try applying some toothpaste for unexpected results. 3. Cleaners: Avoid using abrasive cleaners on car glass as such damage can affect the driver's visibility. 4. Glass rust: Glass rust is relatively difficult to remove. If laundry detergent and dish soap don’t work, first wipe with a damp cloth, then use a clean damp cloth dipped in a little alcohol or liquor to scrub the car glass vigorously. This can make the glass shine like new.

What causes a loud noise from the car's chassis?

Possible causes of abnormal noises from the car chassis are as follows: 1. Noises when starting the vehicle are generally related to suspension system faults, or may be caused by loose or damaged engine mounts. 2. Noises during steering may be due to issues with the steering system or suspension system. During turning, the vehicle's tilt causes deformation of the suspension system, which also participates in the movement. 3. Noises during driving on good road conditions may be caused by faults in the braking system components, such as loose or worn parts, out-of-round brake drums, or uneven brake discs. 4. Problems with the bearings connecting moving and static parts. If it's a bearing issue, the driver can identify it by applying slight brakes; if the noise remains unchanged during uniform motion with brakes applied, it indicates a bearing problem. 5. Noises during driving on poor road conditions are mostly related to suspension system issues, but may also be caused by loose braking system components.
