What are the taboos for NiMH No.7 batteries and what are the maintenance methods?

　　The taboo of NiMH No.7 batteries is that it is strictly forbidden to smoke near the battery, and it is strictly forbidden to generate any flames or sparks. When cleaning the battery, be sure to use a damp cloth, not a dry cloth; in addition, the maintenance method of the forklift battery is to regularly check whether the battery connection wires and lead wires are loose or damaged. It is strictly prohibited to invert, lie down, throw, roll, press heavily, and avoid contact with any toxic gases and organic solvents. Next, I will introduce the details to you.

　　1. Taboos of NiMH No.7 batteries

　　1. The battery of the electric storage forklift will produce hydrogen gas, which may cause an explosion. It is strictly forbidden to smoke near the battery, and it is strictly forbidden to produce any flames or sparks. The battery must be stored or charged in a well-ventilated area, but not near an exhaust vent to avoid corrosion caused by acid mist.

　　2. Warehouse forklift battery fluid contains corrosive liquid, which may cause severe burns. Avoid contact with skin, eyes or clothes. If an accident occurs, please rinse immediately with plenty of water and seek medical advice quickly.

　　3. When inspecting or maintaining the battery of a storage forklift, please use rubber gloves to avoid electric shock.

　　4. The surface or connections of the storage forklift battery must be kept clean. Dust, impurities, etc. must be removed with a damp cloth, otherwise electricity leakage may occur or even cause a fire.

　　5. When cleaning the battery, be sure to use a damp cloth, not a dry cloth.

　　6. Do not use tools to connect the positive and negative terminals of the battery.

　　7. When charging, the electrolyte temperature should not exceed 50 degrees Celsius to avoid damage caused by electrolyte overflow. Pay special attention to it during the day in summer.

　　8. Before unplugging the battery plug, be sure to turn off the forklift's key switch and charger switch to avoid sparks.

　　9. The electrolyte level should not be lower than the minimum limit, otherwise the battery will be easily heated and burned.

　　2. Forklift battery maintenance methods

　　1. Check whether the battery connection wires and lead wires are loose or damaged, and adjust or replace them in time.

　　2. Measure and check the battery voltage, electrolyte density, liquid level height and temperature at least once a week.

　　3. Check whether there is any accumulated water in the battery box. If any accumulated water is found, it must be sucked up immediately. If electrolyte flows into the battery box, it should be neutralized with alkaline water, diluted with clean water and drained.

　　4. NiMH No.7 batteries that leave the factory uncharged should be stored in a clean and dry room with a temperature of 5-40°C. The storage period of the battery is 2 years from the date of shipment. If stored for more than 2 years, the initial charging time of the battery should be appropriately extended.

　　5. For NiMH No.7 batteries that have been initially charged and shipped out of the factory, the battery surface should be kept clean and dry, and stored in a dry, clean, and well-ventilated warehouse with a temperature of 5-40°C. At the same time, avoid direct sunlight and keep away from heat sources.

　　6. NiMH No.7 batteries are strictly prohibited from being turned upside down, placed horizontally, thrown, rolled, or heavily pressed. Avoid contact with any toxic gases and organic solvents. It is strictly prohibited for any metal or impurities to fall into the battery. If the battery is left unused for a long time, it must be recharged once a month.
