Nickel-Cadmium (Ni-Cd) batteries are widely used in critical industrial applications due to their excellent reliability, long service life, wide operating temperature range, and strong resistance to harsh environments.

During the manufacturing, transportation, installation, and operation processes, battery safety is always a key consideration. One important safety feature of Ni-Cd batteries is the valve system, which includes two different configurations: the transport valve and the operating valve.

Although they have different functions, they are not two completely independent valve systems. Instead, they represent different protection configurations used during different stages of the battery lifecycle.

What Is a Transport Valve for Ni-Cd Batteries?

The transport valve is a temporary protection component installed during transportation and storage.

Its main purpose is to protect the battery before installation and prevent potential damage caused by external factors.

During transportation, batteries may experience vibration, dust exposure, or long storage periods. The transport valve helps:

• Prevent dust and foreign materials from entering the battery;
• Reduce the risk of electrolyte leakage caused by vibration or improper handling;
• Provide additional protection before the battery is put into service.

However, the transport valve is only designed for transportation and storage conditions. It must be removed before installation, and the battery should never be operated or charged while the transport valve is installed.

What Is an Operating Valve for Ni-Cd Batteries?

The operating valve is the permanent safety valve used when the battery is working normally.

During charging and discharging, chemical reactions inside the battery may generate gas. If abnormal conditions occur and internal pressure increases excessively, the operating valve automatically releases gas pressure to protect the battery housing and improve operational safety.

Its key functions include:

• Maintaining safe internal pressure;
• Releasing excess gas when necessary;
• Preventing battery damage caused by overpressure;
• Supporting stable long-term operation in industrial environments.

In simple terms, the transport valve protects the battery when it is “resting” during transportation and storage, while the operating valve protects the battery when it is “working” in actual applications.
