As an important power source of ships, marine batteries have unique characteristics and requirements. This article will summarize and introduce the relevant knowledge points of marine batteries to help readers understand the characteristics, selection and maintenance of marine batteries more comprehensively.

1. Types and features of marine batteries:

marine batteries are mainly divided into lead-acid batteries, lithium batteries and lithium titanate batteries. Lead-acid batteries have low cost and high reliability, and are suitable for large-capacity applications; lithium battery high energy density, long service life, but high price; Lithium titanate battery has higher safety and stability.

2. Key points of marine battery selection:

• battery capacity: determine the battery capacity according to the power demand and service time of the ship.
• Working environment: select a suitable battery type considering factors such as humidity and high temperature in the marine environment.
• Security: Select a battery with good safety performance to prevent safety accidents caused by battery failure.

3. Marine battery maintenance and management:

• charge management: reasonably control the charging voltage and current to avoid overcharging or overdischarging.
• Temperature Monitoring: check the battery temperature regularly to ensure that it is within the appropriate operating temperature range.
• Maintenance: Clean the battery surface regularly, check whether the terminal connection is loose, and prolong the battery life.

4. Safety precautions for marine batteries:

• prevent overcharging and overdischarging: avoid overcharging or overdischarging the battery, which will shorten or damage the battery life.
• Regular inspection: regularly check the battery status, connecting line and surrounding environment to ensure the safe use of the battery.
• Emergency Handling: establish emergency handling procedures. Once a battery failure occurs, deal with it in time to avoid the expansion of the accident.

As an important energy device for ships, marine batteries play a vital role in the operation of ships. Understanding the types, selection points, maintenance and management as well as safety precautions of marine batteries is helpful to ensure the safe and reliable operation of batteries and improve the operation efficiency and safety of ships.
