why maintenance free batteries are used on ships

The reasons for using maintenance-free batteries on ships are as follows:

Maintenance-free batteries do not require regular addition of distilled water or electrolyte, which reduces the workload and cost of maintenance and avoids the risk of battery performance degradation or damage caused by improper addition of water.

The maintenance-free battery adopts a sealed structure and will not leak acid or emit acid mist, which reduces corrosion and harm to ship equipment and personnel, and also improves the ship's environmental performance.

Maintenance-free batteries have the characteristics of small internal resistance, good low-temperature starting performance, and long power storage time, and are adapted to the needs of various complex and harsh environments and situations that ships encounter at sea.

The maintenance-free battery complies with the requirements of the Global Maritime Distress and Safety System (GMDSS) of the International Maritime Organization (IMO) and can effectively communicate in distress and safety situations to ensure safe navigation and effective management of ships.
