Nickel plated terminal poles made of Changhong NF-S series NiFe threaded steel bars are welded onto batteries are fitted with special the current carrying bar to assemble flame arresting flip-top vents to plate groups. The cell cover and ensure the battery works safely and terminal pole are sealed by reliably , while providing good compression rubber washers, which ventilation during charging. of steel, the plates cannot be Changhong NF-S series NiFe gradually weakened by repeated cell consists of two groups of cycling, which gives Changhong plates, the positive plates NF-S series NiFe...

1.5 Comparison Between VRLA and NF-S Series NiFe Cell 1.5.2 Cost Comparison Between VRLA and NiFe Cell 1.5.1 Table1 Characteristic comparison Sheet Cost effectiveness Item Name Lead Acid Battery There are three distinct parts contribute to the cost of a battery system: · Norminal Voltage Floating Charge Voltage Temperature factor during floating charge Preventive maintenance Initial investment: including the cost of purchase, spares, tools, and installation. · Preventive maintenance Maintenance cost: including unexpected and expensive downtime costs, Initial cost Replacement cost: including...

1.6.3 Effect of temperature on performance Variations in ambient temperature affect the performance of a battery. The capacity de-rating factors, which 9000 The Changhong NF-S series NiFe cell is adaptable to a wide range of depth Available capacity of discharge (DOD). The number of cycles varies with DOD required. The lower the DOD is, the higher the cycle number. The numbers of cycles reach thousands in shallow discharge End voltage 1.0V discharge. The figure at right shows hundreds of cycles during deep applications, while it can only reach are required in sizing cell to compensate for...

Overcharging a NF-S battery will overcharge current is consumed by the self-discharge of the electrodes. The Charge efficiency depends on the state of charge and ambient electrolyte into oxygen and temperature. The graph below 1.7 water loss. In theory, the quantity of water consumed can be calculated according to the Faradic equation that each Ah of overcharge breaks down 0.366cc of water. The electrolysis of 1cc water generates 2000cc of mixture gas in the proportion of 2/3 hydrogen and 1/3 oxygen. In reality the water loss Water Consumption grams/months,Ah hydrogen, so pure distilled...

T rouble Shooting Trouble No enough electrolyte, and the level of electrolyte is below the minimum level line. Add distilled water, adjust the electrolyte density then overcharge the cell The electrolyte has been used for a long time and the carbonate content inside is too high. Drop in the cell capacity Harmful impurities in electrolyte The charge/discharge parameters are not correct. Short-circuit or slight short-circuit inside the cell. Short-circuit or slight short-circuit occurs from outside the cell. Replace the electrolyte after cleaning. Overcharge the cell. For other causes, repair...
