FAQs

How to Identify Car Battery Terminals’ Polarity

1. Locating the Battery Terminals:
   To begin, open the hood or trunk of your car to access the battery. Look for the terminals, which are typically metal posts positioned on top of the battery. The positive and negative terminals are usually located side by side.
2. Identifying the “+” and “-” Signs:
   Next, examine the terminals closely for the presence of “+” and “-” signs. These signs indicate the polarity of the terminals. The “+” sign represents the positive terminal, while the “-” sign represents the negative terminal. In some cases, the terminals may be covered with plastic caps, which can also help in identifying the polarity.
3. Plastic Caps and Color Indicators:
   If the terminals are covered with plastic caps, pay attention to their colors. The red cap is associated with the positive terminal, while the black cap corresponds to the negative terminal. These color indicators provide an additional visual cue to ensure the correct identification of the terminal polarity.
