routine maintenance of marine batteries

1. Requirements for battery rooms: For flooded battery packs, the lighting should be controlled outdoors and a no-smoking sign should be posted. There should be good ventilation in the room. For the emergency generator room without a separate battery room, the flooded battery should be stored in a closed battery box, and the battery box has an independent ventilation pipe leading directly to the outside, and there should be tools for preparing battery electrolyte in the room. What needs to be reminded is that some ordinary flashlights are placed in the battery toolbox, which does not have the explosion-proof function, which is superfluous. Valve-regulated battery packs are no longer included in this list. Fire extinguishers should be stored in the battery room. Protective apron, glasses, rubber gloves, measuring tools, hydrometer, eyes. No other items unrelated to maintenance are allowed to be stored.

2. The battery should be inspected every week, the voltage should be measured, and the battery should be kept clean. The inspection of the battery should also be included in the battery record book. When replacing the battery, the model, capacity, and replacement date should be recorded in the "Battery Charging and Maintenance Record Book;

3. Necessary receiving and cleaning should be carried out on the wiring of the battery on a regular basis, and Vaseline oil should be applied to prevent corrosion. The battery room should be kept clean and no irrelevant debris should be piled up.

4. Before charging, check that there is no hot work near the battery room, and keep the upper air duct open to keep the battery room well ventilated.

5. The battery should be discharged and charged frequently. If there are two sets of batteries, they should be numbered and exchanged for charging and discharging to prevent the other set from being damaged if it is not charged for a long time. Before charging, the battery voltage, charging start and end time should be recorded in detail.

6. After the battery is running and discharged, it should be supplemented immediately. If the battery is left for a long time after discharge, the capacity may not recover to the original capacity when recharging.
