Inhalation Sulfuric Acid: Remove to fresh air immediately. Consult a physician. Lead: Remove from exposure, gargle, wash nose and lips; consult physician. Ingestion Sulfuric Acid: Give large quantities of water. Consult a physician. Lead: Consult physician immediately. Skin Sulfuric Acid: Flush with large amounts of water for at least 15 minutes; remove contaminated clothing completely. If symptoms persist, seek medical attention. Wash contaminated clothing before reuse. Discard contaminated shoes. Lead: Wash immediately with soap and water. Eyes Sulfuric Acid and Lead: Flush immediately with large amounts of water for least 15 minutes while lifting lids. Seek immediate medical attention.
闪点(采用的方法)：不可燃的可燃极限：*氢气体灭火剂：ABC级灭火器，限值：Lel=4.1%(氢气)UEL=74.2% 在牢房里。热冲击可能导致电池外壳和/或外壳破裂。在电池充电过程中可能会产生氢气。特别消防程序：如果有电池 RGE，关闭电源。使用正压、自给式呼吸器灭火。施加到电解质上的水产生热量并使其飞溅。耐磨的衣服。VEVE 倾斜区域良好。 不寻常的火灾和爆炸危险： 在正常的电池操作或充电时，电池中会产生氢气和氧气气体。 (氢是易燃的，氧是助燃剂。 (燃烧)在电池过度充电时，这些气体通过通风口进入空气。为了避免火灾或爆炸的危险，请将火花和其他点火源远离电池。别这么说 金属物体同时接触电池的正负端子。通风良好。
Flash Point (Method Used): non flammable Flammable Limits: *Hydrogen Gas Extinguishing Media: Class ABC extinguisher, Limits: LEL = 4.1% (Hydrogen Gas) UEL = 74.2% NOTE: CO2 may be used, but not directly on the cell. The thermal shock may cause cracking of the battery case and/or cases. Hydrogen gas may be generated during battery charging. Special Fire Fighting Procedures: If batteries are on charge, turn off power. Use positive pressure, self-contained breathing apparatus in fighting fire. Water applied to electrolyte generates heat and causes it to splatter. Wear acid resistant clothing. Ventilate area well. Unusual Fire and Explosion Hazards: Hydrogen and oxygen gases are generated in cells during normal battery operation or when on charge. (Hydrogen is flammable and oxygen supports combustion). These gases enter the air through the vent caps during battery overcharging. To avoid risk of fire or explosion, keep sparks and other sources of ignition away from the battery. Do not allow metal objects to simultaneously contact both positive and negative terminal of batteries. Ventilate area well.
目前UPS电源使用的电池基本上都是免维护铅酸蓄电池，在使用的过程中，我们都会尽量避免UPS蓄电池深度放电，因为这样将会影响电池本身的特性，不过也有不同的情况，需要进行深度放电。
UPS蓄电池深度放电管理系统，定时自动关机方案。当市电停电后，如果蓄电池组因放电电流较小而使它的放电时间超过原设计的"满载后备供电时间"时，UPS所允许的长放电时间为原来所预置的蓄电池“后备供电时间”的3倍。当放电时间达到此时刻时，不管ups蓄电池组是否还有足够的容量可供使用，UPS都将执行自动关机操作，不让蓄电池因放电电流过小而进入"深度放电"工作区。例如:如果UPS的蓄电池组后备时间为l5min(带负载)，不管用户的实际负载有多轻，只要市电的停电时间超过45min，UPS都将进入自动关机状态(尽管此时的蓄电池还有数量可观的可供安全使用的容量存在)。
对UPS电源主机而言，肯定有利于降低逆变器的故障。然而，对于同UPS配套的长延时蓄电池组而言，则会因蓄电池被“深度放电”而造成蓄电池的实际使用寿命成10倍的缩短。所以在使用UPS电源的过程中，应当尽量避免蓄电池深度放电。
