　　定期檢查各(ge)單(dan)(dan)(dan)元電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)端電(dian)(dian)(dian)(dian)(dian)壓和內阻。對12V單(dan)(dan)(dan)元電(dian)(dian)(dian)(dian)(dian)池(chi)來說，在(zai)檢查中如果發現各(ge)單(dan)(dan)(dan)元電(dian)(dian)(dian)(dian)(dian)池(chi)間的(de)端電(dian)(dian)(dian)(dian)(dian)壓差(cha)超過0.4V以上或電(dian)(dian)(dian)(dian)(dian)他的(de)內阻超過80mΩ以上時，應該對各(ge)單(dan)(dan)(dan)元電(dian)(dian)(dian)(dian)(dian)池(chi)進行均衡(heng)充(chong)電(dian)(dian)(dian)(dian)(dian)，以恢復(fu)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)內阻和消除各(ge)單(dan)(dan)(dan)元電(dian)(dian)(dian)(dian)(dian)池(chi)之間的(de)端電(dian)(dian)(dian)(dian)(dian)壓不平衡(heng)。均衡(heng)充(chong)電(dian)(dian)(dian)(dian)(dian)時充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓取13.5～13.8V即可(ke)。經過良好均衡(heng)充(chong)電(dian)(dian)(dian)(dian)(dian)處理(li)的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)絕大多(duo)數都可(ke)將其內阻恢復(fu)到30mΩ以下(xia)。

　　UPS電源在運行過程中(zhong)，由于各單(dan)元電池特性(xing)隨時間變化而(er)產生的(de)上述不(bu)(bu)均(jun)衡(heng)性(xing)是不(bu)(bu)可(ke)能再依靠UPS電源內部的(de)充電回(hui)路來(lai)(lai)消除的(de)，所以對(dui)這(zhe)種特性(xing)已發生明顯(xian)不(bu)(bu)均(jun)衡(heng)性(xing)的(de)電池組，若不(bu)(bu)及(ji)時采取脫機均(jun)充處理的(de)話，其不(bu)(bu)均(jun)衡(heng)度(du)就會越(yue)(yue)來(lai)(lai)越(yue)(yue)嚴(yan)重。

重新浮充

　　電(dian)他的使用壽命與它被放(fang)電(dian)的深(shen)(shen)度(du)密切(qie)相關。UPS電(dian)源(yuan)所帶的負載(zai)越輕，市電(dian)供(gong)電(dian)中斷(duan)時，蓄電(dian)他的可供(gong)使用容量(liang)與其(qi)額(e)定容量(liang)的比值越大，在此情況(kuang)下，當UPS電(dian)源(yuan)因(yin)電(dian)池電(dian)壓過(guo)低而自動關機(ji)時電(dian)池被放(fang)電(dian)的深(shen)(shen)度(du)就比較深(shen)(shen)。

　　實際過程如何減(jian)少電(dian)(dian)(dian)池(chi)被深(shen)度放(fang)電(dian)(dian)(dian)的(de)事(shi)情發生呢？方法(fa)很簡單：當UPS電(dian)(dian)(dian)源(yuan)(yuan)處于市電(dian)(dian)(dian)供電(dian)(dian)(dian)中斷，改由(you)蓄電(dian)(dian)(dian)池(chi)向(xiang)逆變(bian)器(qi)供電(dian)(dian)(dian)狀態時(shi)，絕大多數UPS電(dian)(dian)(dian)源(yuan)(yuan)都會以間隙4s左右響一(yi)次(ci)的(de)周期性報警聲，通知用戶現在是由(you)電(dian)(dian)(dian)池(chi)提供能量。當聽到報警聲變(bian)急促(cu)時(shi)，就說明電(dian)(dian)(dian)源(yuan)(yuan)已處于深(shen)度放(fang)電(dian)(dian)(dian)，應立即進(jin)行應急處理，關閉(bi)UPS電(dian)(dian)(dian)源(yuan)(yuan)。不(bu)是迫不(bu)得(de)以，一(yi)般不(bu)要讓(rang)UPS電(dian)(dian)(dian)源(yuan)(yuan)一(yi)直工(gong)作到因(yin)電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓過低而自動關機(ji)才結束。

利用供電高峰充電

　　UPS電(dian)(dian)(dian)源(yuan)用(yong)的(de)免維護密封電(dian)(dian)(dian)池(chi)不能用(yong)可(ke)控硅式(shi)的(de)“快速充電(dian)(dian)(dian)器(qi)”進行(xing)充電(dian)(dian)(dian)。這(zhe)是因為這(zhe)種充電(dian)(dian)(dian)器(qi)會(hui)造(zao)成(cheng)蓄(xu)電(dian)(dian)(dian)池(chi)同時處于既(ji)“瞬(shun)時過流(liu)充電(dian)(dian)(dian)”又“瞬(shun)時過壓(ya)(ya)充電(dian)(dian)(dian)的(de)惡劣充電(dian)(dian)(dian)狀態。這(zhe)種狀態會(hui)使電(dian)(dian)(dian)池(chi)可(ke)供使用(yong)容量大大下降，嚴重時會(hui)使蓄(xu)電(dian)(dian)(dian)池(chi)報廢。在(zai)(zai)采用(yong)恒壓(ya)(ya)截(jie)止(zhi)型充電(dian)(dian)(dian)回(hui)路的(de)UPS電(dian)(dian)(dian)源(yuan)時，注意(yi)不要(yao)將電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)(ya)過低(di)保護工(gong)作(zuo)點調(diao)得過低(di)，否則，在(zai)(zai)它(ta)充電(dian)(dian)(dian)初期容易產生過流(liu)充電(dian)(dian)(dian)。

　　當(dang)然，最好(hao)選用既具有恒流，又有恒壓的充電器(qi)對其(qi)進(jin)行充電。
