Types of Car Batteries and Terminals
There are several types of car batteries and terminals available, including:
| Type of Battery | Type of Terminal |
|---|---|
| Lead-Acid | Positive (+) and Negative (-) Terminals |
| AGM (Absorbent Glass Mat) | Positive (+) and Negative (-) Terminals |
| EFB (Enhanced Flooded Battery) | Positive (+) and Negative (-) Terminals |
| Lithium-Ion | Positive (+) and Negative (-) Terminals |
Regardless of the type of battery or terminal, the correct connection is crucial for the proper functioning of the electrical system. In the following section, we will provide a step-by-step guide on which terminal to connect first on a car battery.

Step 1: Identify the Positive (+) Terminal
The positive terminal is usually marked with a “+” sign or a red color. It is located on the side of the battery and is connected to the starter motor and ignition system.
Step 2: Identify the Negative (-) Terminal
The negative terminal is usually marked with a “-” sign or a black color. It is located on the side of the battery and is connected to the engine block and other electrical systems.
Step 3: Connect the Positive (+) Terminal First
Begin by connecting the positive terminal to the starter motor and ignition system. This is usually done by attaching the positive terminal cable to the starter motor and ignition system.
Step 4: Connect the Negative (-) Terminal Second
Once the positive terminal is connected, connect the negative terminal to the engine block and other electrical systems. This is usually done by attaching the negative terminal cable to the engine block and other electrical systems.
Step 5: Check the Connections
Once both terminals are connected, check the connections to ensure they are secure and not loose. Make sure the terminals are not touching each other or any other metal parts. (See Also: How Accurate Are Car Battery Testers? A Reliable Guide)
