What is the difference between red and blue labels on car batteries?
2 Answers
Battery terminal with red label indicates the positive pole of the battery, while blue label indicates the negative pole. This labeling helps consumers better distinguish between the positive and negative terminals of the battery. Here is more information about car batteries: 1. The battery is a crucial component in a vehicle. When the engine is not running, the battery powers all electronic devices in the car and is also responsible for starting the engine. 2. Avoid sitting in the car for extended periods using electronic devices when the engine is off, as this will reduce the battery's lifespan. During winter, try not to park the car outside overnight, as low temperatures can negatively affect the battery's lifespan.
The main differences between red-label and blue-label car batteries lie in performance and application scenarios. For example, the Varta red-label series has higher CCA (Cold Cranking Amps) values, enabling reliable cold starts in sub-zero temperatures, making it ideal for off-road vehicles or cold regions. The blue-label is an entry-level option with good cost-performance, perfectly adequate for daily urban driving. Price-wise, the red-label costs dozens of RMB more, but offers longer lifespan (several extra years) for frequent long-distance drivers or high-power vehicles, while the blue-label saves costs but requires regular battery checks. Having replaced multiple car batteries myself, I find red-labels more durable, though blue-labels are easier to install – just remember to apply anti-corrosion grease on terminals to prevent rust.
