What does a red float in the battery liquid level indicator indicate?

A red float in the battery liquid level indicator signifies a low liquid level. In a battery system, particularly in lead-acid batteries typically used in forklifts, maintaining the correct electrolyte level is crucial for optimal performance and longevity. When the liquid level drops too low, it can lead to damage of the battery cells and decrease the efficiency of the battery.

The red float is designed to provide a visual cue to operators, allowing them to monitor the liquid level effectively. If the float is red, it indicates that the electrolyte is below the recommended threshold, and the battery needs to be checked for water levels and potentially refilled to prevent any operational issues.
