1. 12V battery

A battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to achieve recharging through reversible chemical reactions, usually referring to lead-acid batteries. It is a type of secondary battery.

2. Overview

A battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to achieve recharging through reversible chemical reactions, usually referring to lead-acid batteries. It is a type of secondary battery. Its working principle: When charging, external electrical energy is used to regenerate internal active substances, storing electrical energy as chemical energy. When discharging, chemical energy is converted back into electrical energy for output, such as commonly used mobile phone batteries in daily life.

3. Some issues to pay attention to when using and maintaining batteries

(1) If a battery is not used for a long time, it will slowly discharge on its own until it is scrapped. Therefore, the car should be started at regular intervals to charge the battery. Another method is to unplug the two electrodes from the battery. It is important to note that the positive and negative electrode wires should be unplugged from the electrode posts. First, unplug the negative electrode wire or remove the connection between the negative electrode and the car chassis. Then unplug the other end with the positive symbol (+), the battery has a certain service life and needs to be replaced at a certain period of time. When replacing, the above order should also be followed, but when connecting the electrode wires, the order is exactly the opposite: first connect the positive electrode, and then connect the negative electrode.

(2) When the ammeter pointer shows insufficient battery storage, it should be charged in a timely manner. The storage capacity of the battery can be reflected on the dashboard. Sometimes during the journey, it is found that the battery level is insufficient and the engine cannot be started. As a temporary measure, you can seek help from other vehicles and use their batteries to start the vehicle. Connect the negative and negative terminals of the two batteries, and the positive and negative terminals.

The charging time of a battery should be determined based on the size of the battery capacity and charging current. 12V batteries can charge up to 1AH to 200AH, and generally charge for no less than 24 hours. Of course, charging with a high current will be faster. However, many devices charge the battery with constant current in the first stage and constant voltage in the second stage, so as to maximize the battery life. If only a large battery is used for charging, the charging time of the battery is short, but it also affects the battery life and capacity
