Regularly check battery voltage: Use a voltmeter to regularly check battery voltage, especially before long-distance voyages. This can help you promptly detect whether the battery is in good condition, avoiding startup failures or other device malfunctions caused by insufficient battery power.
Keep battery terminals clean: Corrosion of battery terminals can reduce battery performance and may even lead to poor contact. Regularly using battery terminal cleaner for cleaning and applying a thin layer of Vaseline or rust proof oil can effectively prevent corrosion and ensure the reliability of battery connections.
Secure Connection: Ensure that all battery connections are securely fastened and free from corrosion. Loose connections not only reduce power transmission efficiency, but may also cause sparks and pose safety hazards.
Check electrolyte level: For rich electrolyte lead-acid batteries, regularly check the electrolyte level and add distilled water as needed. Insufficient electrolyte can lead to a decrease in battery performance and even damage to the battery.
Proper storage: When storing the vessel for a long time, the battery should be disconnected and stored in a cool and dry place. Avoid storing batteries in damp or high-temperature environments, as this can help extend their lifespan.
