Battery charging methods include float charging and equalization charging. Float charging maintains sufficient charge, while equalization charging charges the battery at a constant current and for a fixed duration. Equalization charging is a mode frequently used by professional maintenance personnel for battery upkeep. This mode helps activate the battery's chemical properties, with the equalization charging voltage typically being 1.175 times the battery's rated voltage. During float charging, the current supplied to the battery should compensate for the charge lost due to self-discharge, and the voltage should not be too high to avoid severe overcharging, which could shorten the battery's lifespan. The battery is an essential part of a car and can be categorized into traditional lead-acid batteries and maintenance-free batteries.

Is it troublesome to transfer a 4S store test drive car to an individual?

Transferring a 4S store test drive car to an individual is not troublesome. Both owners should bring complete vehicle documents to the DMV for the transfer. If the test drive car is registered under a company name rather than an individual, the company needs to provide a certificate and a copy of its business license. Below are the precautions for individual used car transfers: Ensure the property certificate is legitimate: Pay special attention to the embossed number, engine number, and registration date on the property certificate. Besides verifying these details, check for any signs of alteration, as tampering may indicate a fraudulent transaction. Check for traffic violation records: Before transferring a used car, check whether the vehicle has any outstanding traffic violations and whether it is within the validity period of compulsory traffic insurance. Only vehicles with no violations and valid insurance can be transferred. Generally, vehicles with violations cannot be transferred until the violations are resolved. Verify the vehicle purchase tax payment receipt: Always inspect the original tax receipt for the used car. Some vehicles may not have paid purchase tax, and after the transfer, the new owner may be required to pay the outstanding tax, which can be a significant expense. Therefore, it is crucial to clarify who will bear this cost.

Why Don't 4S Shops Use Torque Wrenches?

4S shops do not use torque wrenches because the torque measurements are inaccurate. They can only tighten based on the number of turns. Below is an introduction to torque wrenches: Introduction: A torque wrench, also known as a moment wrench or torque spanner, is a type of wrench generally categorized into electric torque wrenches and manual torque wrenches. Principle: Torque is the product of force and distance. When tightening threaded fasteners such as screws, bolts, and nuts, it is necessary to control the applied torque to ensure the threads are securely fastened without being damaged due to excessive torque, hence the use of a torque wrench. Application: Torque wrenches are used for tightening bolts. High-strength bolts can be divided into two types: twist-off type and large hexagon type. According to national standards, twist-off high-strength bolts come in four sizes: M16, M20, M22, and M24.
