How to Connect Jumper Cables for a Car?
1 Answers
When connecting jumper cables for a car, first confirm whether it is 12V and ensure the negative terminal is grounded before proceeding with the connection. Below is relevant information: 1. Positive first, then negative: Always follow the sequence of "positive first, then negative" because once the negative is connected, it forms a circuit for the car. If the positive is connected last, when tightening the screw, a conductive wrench accidentally touching the car's metal would be equivalent to connecting the battery's positive and negative terminals together. This not only causes a short circuit in the car battery but may also lead to "sparking" in severe cases. 2. Battery: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Car batteries are categorized into conventional batteries, dry-charge batteries, and maintenance-free batteries. Typically, the term "battery" refers to a lead-acid battery. The normal lifespan of a car battery ranges from 1 to 8 years, largely depending on the vehicle's usage conditions.
