Lead-acid batteries do not need to be fully discharged before charging. Here is the relevant introduction: 1. Suggestion: For the first charge of a new electric vehicle, there is no need to deliberately discharge the battery completely before charging. Lead-acid batteries have no memory effect. It is generally recommended to charge the battery when the remaining capacity is 30% to 40%, which is the optimal time. It is usually not recommended to charge for more than 12 hours. 2. First charge: When charging the battery for the first time, the charger may heat up quickly and reach a high temperature, especially during summer charging. Do not place the charger on objects that are prone to heat or combustion, and it is best not to place it on the seat of the electric vehicle to prevent fire. Many cases of spontaneous combustion of electric vehicles have occurred during charging, so please be very careful.

What Causes Bubbles in Rear Windshield Tinting?

Rear windshield tinting may develop bubbles due to the following reasons: Impact of Heating Elements: The rear windshield contains numerous heating elements, which can affect the tinting to some extent. The presence of these heating elements causes the tint film to heat up when the rear windshield is warmed, leading to bubble formation. If there are numerous large bubbles, it is advisable to remove and reapply the tint film. Effect of Low-Quality Film: Over time, low-quality tint films exposed to UV rays may release toxic gases like formaldehyde, resulting in bubble formation. If bubbles appear due to this reason, it is necessary to replace the car's tint film immediately, as continued use can pose health risks.

Is Vehicle Inspection Strict During National Day?

What Are the Reasons for Stiff and Jerky Gear Shifting in Manual Transmission?

Manual transmission gear shifting can be stiff and jerky due to the following reasons: Rusty transmission shaft: A rusty transmission shaft prevents the clutch driven disc from moving smoothly. Poor return movement makes it difficult for the gears to engage along the normal path. Additionally, prolonged use or insufficient transmission oil can also lead to rust. Clutch malfunction: Insufficient clutch separation travel results in incomplete clutch disengagement, making it hard to shift gears. Alternatively, deformation of the clutch pressure plate assembly's drive plate due to certain reasons can cause poor separation. Cold gear shifting: Shifting gears in a cold car can make the gear feel stiff. After all, at lower temperatures, the viscosity of the gear oil in the transmission does not reach the ideal state, leading to suboptimal lubrication.
