How Long Can a Battery Last After Leaking?

If the battery has only a small amount of leakage, it can still be used. If there is excessive leakage, you can refill the electrolyte yourself, but for safety reasons, it is best to replace the battery directly. Here are some precautions regarding car batteries: 1. When not in use for a long time in winter: If the car is not used for an extended period during winter, the battery should be removed to prevent power loss or damage due to freezing. 2. Regularly charge the battery: The battery should be charged periodically, and the car should be started from time to time. 3. After turning off the engine: After turning off the engine, avoid using car electronics. If necessary, start the car to ensure normal power supply. 4. Regular battery cleaning: Clean the car battery regularly, especially the terminal connections, and apply professional grease to protect the wiring harness.

What Does the Voltage and Ampere Hour of a Battery Mean?

Voltage refers to the terminal voltage of the battery, while ampere hour indicates the battery's capacity, meaning how much electricity it can store. Below is an introduction to volts and amperes: 1. Volt: The international unit of voltage is the volt (V), with other commonly used units including millivolt (mV), microvolt (μV), and kilovolt (kV). 2. Ampere: The ampere is the base unit of electric current in the International System of Units, abbreviated as amp. Symbol A. It is named in honor of the French physicist A. Ampère, who proposed the famous Ampère's law in 1820.

What is the charging current for electric vehicles?

Electric vehicle charging current is 15A. The following are precautions for maintaining pure electric vehicle batteries: Regularly start the vehicle: If a battery remains unused for a long time, it will gradually self-discharge until it becomes unusable. Therefore, the vehicle should be started periodically to charge the battery. Charge promptly: When the battery level indicator shows insufficient charge, the battery should be charged immediately. The battery's charge level can be monitored on the dashboard. Regular battery inspection: During daily driving, frequently check whether the small holes on the battery cover are ventilated. If these holes are blocked, the generated hydrogen and oxygen cannot escape. When the electrolyte expands, it may rupture the battery casing, affecting the battery's lifespan.

What is the small dot on the headlight cover?

The small dot on the headlight cover is actually a convex lens on the headlight, designed to diffuse light and ensure even distribution of illumination ahead, preventing concentrated beams that could create blind spots. Here's an introduction to car lights: 1. Headlights: Commonly known as front lights, they come in low beam and high beam variants. Their primary function is to provide illumination for night driving. Low beams are used in urban areas with streetlights, while high beams are for rural roads or highways without adequate lighting. There's also a high-low beam switch used for signaling or overtaking. Remember not to keep high beams on continuously during oncoming traffic, avoiding becoming a so-called 'high beam hog'. 2. Width indicator lights: Mainly used at night to display the vehicle's width and length, alerting other drivers and pedestrians to your presence. They should be turned on when rear visibility is poor through the mirrors or during rainy/foggy conditions to enhance driving safety. 3. Daytime running lights: To avoid increasing battery load, headlights shouldn't be used during daytime. These daytime running lights were created specifically for daytime driving to alert other road users. Typically using white LED lights, they're energy-efficient, not overly bright, yet serve as effective warning signals.

Does Slight Water Exposure to the Chassis Have Any Impact?

If the car is not submerged for an extended period, slight water exposure to the chassis is generally not a problem. This is because the car's surface is designed with multiple waterproofing measures. Even if it's not completely waterproof, short-term exposure to water usually does not cause issues. However, for safety reasons, it's advisable to inspect certain areas after driving through water, such as the engine compartment, air intake, and brake discs, to ensure there are no foreign objects that could affect driving safety. Here are the correct methods for driving through water: 1. Assess the depth of the water: First, determine the depth of the water. If it does not exceed half the height of the wheels, it is generally safe to proceed; otherwise, it is not recommended. 2. Slow down: When entering a waterlogged area, reduce speed and drive slowly. For automatic transmission cars, it's best to use the first gear and engage snow mode if available to prevent wheel slippage. 3. Apply brakes several times: After exiting the water, apply the brakes several times in succession to evaporate any moisture in the brake discs, ensuring braking performance is not compromised.

Should the steering wheel be fully turned again after returning half a turn when reversing into the parking space?

Here are the situations where the steering wheel needs to be fully turned again after returning half a turn when reversing into the parking space: 1. The distance between the car body and the corner of the parking space is too narrow: This occurs because the steering wheel was turned too early when reversing, and it is found that the distance is less than 30 cm before approaching the corner. In this case, the steering wheel needs to be returned half a turn. If the distance is found to be too narrow when reaching the corner, the steering wheel needs to be straightened to allow the car to enter the parking space at an angle, and then the steering wheel should be fully turned again after increasing the distance. 2. The distance between the car body and the corner of the parking space is too wide: This happens because the steering wheel was turned too late when reversing, and it is found that the distance is still more than 30 cm when reaching the corner. In this case, the steering wheel should remain fully turned to reduce the distance until a satisfactory effect is achieved before returning the steering wheel.
