![]() What does the black battery indicator light mean? Precise information about the color of the indicator and its meaning is contained in the battery passport or on the top of the battery label. This color may also indicate a low charge level. White or black – the electrolyte level has dropped, it is necessary to add water and charge the battery.Red – charge level is below 60-80%, the electrolyte density is below 1.23 g/cm3 (∓0.01 g/cm3), but its level is normal.Green – battery is 80-100% charged, electrolyte level is normal, density of electrolyte is above 1,25 g/cm3 (∓0,01 g/cm3).Although there is no single standard, the following colors are most commonly seen in the gauge: The color of the battery charge indicator varies with the battery manufacturer. What Battery Charge Indicator Color Means If the eye remains black or white, it indicates a lack of electrolyte and the need to refill with distilled water or a faulty battery or indicator. Thanks to the light guide, the color of the ball is clearly visible through a window. In the tip there are colored balls of different materials, which float up at a certain density of the acid that fills the battery. Under the peephole on the lid there is a light guide tube, the tip of which is immersed in acid. The principle of operation of the battery charge indicator is based on measuring the density of the electrolyte. ![]() Why you need an eye in the battery and how it works: video The operation and use of this device is described in detail here. The battery gauge itself is a float-type liquid areometer. The battery indicator peephole from the outside looks like a transparent round window that is located on the top cover of the battery, most often near the center cans. Where is the battery peephole located and how does it work? You can learn about what is inside the battery gauge, how it works and why it cannot be trusted unconditionally in this article. However, its readings do not always correspond to the actual condition of the battery. ![]() Many drivers make the decision to service the battery based on the built-in indicator. It is usually green to indicate that the battery is fine, red to indicate the need for charging, and white or black to indicate the need for a water refill. Some car batteries are equipped with a charge indicator, often called an eye.
