The role of the Battery Magic Eye  allows users to intuitively see the battery's charge status. The main principle behind the battery electric eye is that there is a small floating ball at the bottom of the eye. During battery use, the specific gravity of the electrolyte changes. As the specific gravity changes, the height of the floating ball also changes. Through refraction, the display of the electric eye changes accordingly, allowing the user to determine the battery's charge status.

The primary function and role of the battery electric eye is to allow users to determine the battery's charge status by observing the color of the eye. Below is a brief explanation of the operating status of the electric eye:

Single Ball:

• Green: Indicates the battery is fully charged.

• Black: Indicates the battery is low.

• White: Indicates the battery electrolyte is insufficient.

Energy Efficiency: Battery-operated Magic Eyes are energy-efficient, as they typically consume minimal power and have long battery life. This allows for continuous operation in environments where traditional power sources may not be available.

Compact and Portable: The compact size and portability of battery-powered electric eyes make them ideal for temporary setups, mobile equipment, or situations where flexibility is required.

However, if the indicator does not fit tightly enough with the battery, combined with the thermal expansion of the housing and the indicator, acid mist may frequently escape through the assembly gap between the indicator and the battery. This can lead to the formation of a white crystalline substance, which may cause the indicator to malfunction and result in misjudgments. If you would like to learn more about the battery electric eye, please click here.
