Features (1) Long service life High tight assembly process, improve battery assembly tightness to prevent the shedding of live material and improve battery life. The proportion of low-acid electro-hydraulic, improve battery charge acceptance, enhance the capacity of the battery deep discharge cycle. Increase the amount of acid designed to ensure that the battery will not shorten battery life due to electrolyte depletion. Normal GFM series battery float design life up to 15 years (25 ° C) (2) high-rate discharge performance high strength tight assembly technology, the internal resistance of the battery is very small, excellent large current discharge characteristics higher than the average battery 20 [%] or more. (3) self-discharge power low high purity raw materials and special manufacturing processes, self-discharge is small, and can also be stored at room temperature for more than six months do not need to fill. (4) maintenance simple special oxygen absorption cycle design, to overcome the phenomenon of electrolytic dehydration of the battery during the charging process, almost no change in the course of the moisture content of the electrolyte, the battery in the course completely without replenishment, and easy maintenance. (5) The safety inside the battery with a special security. (6) installation simple battery vertical, lateral, the laminate can be installed, installation, small footprint, flexible and convenient. (7) Clean and environmental friendly battery will not produce mist, no corrosion to the surrounding environment and supporting design, the battery can be directly installed in the office or equipment room, and do not need to be treated with preservatives. The charge and discharge characteristics of the battery self-discharge effect. Users, from the manufacturing plant to be delayed for about a few months time. In the lead-acid battery, for example, eight months of storage at 30 ° C ambient temperature, half of the remaining capacity of the battery is only factory, generally a longer charging buy new batteries and UPS Subscription This is called the initial charging. Initial battery charge current should 0.1C to charge the battery can be recharged after the end of the discharge is called the normal charge. UPS generally two charging methods: float and pulse charge. The so-called floating charge refers to the output of the rectifier and battery operated in parallel, and power to the load at the same time, in fact, the rectifier current two routes, all the way to the load, the other way to give the battery to supplement the battery's own internal loss, floating enrich my knowledge of wiring is simple, beneficial to improving the UPS output transient response characteristics. The characteristics of the pulse charging is the charging current varies with the battery capacity, charging in this manner, and can shorten the charging time. A charging voltage of the UPS battery belongs to the standby mode of operation, mains under normal circumstances is charging, discharge only when a power outage. To extend battery life, the UPS charger is generally constant pressure limiting control after the battery is fully converted to a floating state. For the terminal voltage of 12V batteries, normal float voltage 13.5 to 13.8V. Float voltage is too low, the battery charge and dissatisfaction, the float voltage is too high, can cause over-voltage charging. When the the float voltage exceeds 14V, that is considered to be over-voltage charging. Non-charging the battery pack over-voltage, over-voltage charging cause battery electrolyte contains water electrolysis into hydrogen and oxygen to escape, the electrolyte concentration increases, resulting in shorter battery life, or even damage. 2 charging current to the battery charging current to C which means that the actual value of C and the battery capacity. For example, if it is 100Ah battery: C to 100A. Panasonic lead-acid maintenance-free battery charging current is 0.1C, the charging current must not be greater than 0.3C. The charge current is too large or too small will affect the battery life. The ideal charging current should be phased current charging mode, i.e. the the larger initial charging current, charging after a certain time, to a smaller current, switched to a smaller current to the charge end. The design of the charging current ships can be considered to be the over-current charging, when the charge current exceeds 0.3C 0.1C. Avoid quick charger charging, otherwise it would be the battery is the instantaneous overcurrent charge "and" transient over-voltage charging status, or even damage to the battery caused by the battery power available. Cause over-current charging the battery plate bending active material loss caused by the decline in battery-powered capacity, and in severe damage to the battery.
