What do the red, yellow, and blue labels on car batteries mean?
1 Answers
Battery yellow label and blue label differ in performance, warranty period, and price. The yellow label battery offers stable performance with a two-year warranty, while the blue label comes with an 18-month warranty. In terms of price, the yellow label is more expensive than both the blue and black labels. The red standard primarily targets household users, whereas the blue standard is designed for automotive applications. Batteries with red and blue labels use different plate materials, resulting in performance differences. Here are details about car batteries: 1. Battery terminals: The red label on a battery terminal indicates the positive pole, while the blue label marks the negative pole. Manufacturers use these labels to help car owners easily distinguish between the positive and negative terminals. 2. Charge indicator: Near the battery terminals, symbols for positive and negative poles are also marked. The battery charge indicator, also known as the "magic eye," displays black when charging is needed, green for good condition, and white indicating insufficient fluid requiring replacement. If the indicator shows black, the battery needs charging as it has already experienced over-discharge. The charging capacity from the car alone is insufficient, and a charger must be used. It takes about 20 hours to fully charge a car starting battery.
