1、清理

　　維護電池以前，首先(xian)要清(qing)理led被(bei)修電池外表的灰塵，清(qing)除端子上面的沾污和銹蝕。

　　2、打開(kai)排氣閥，觀(guan)察(cha)電(dian)(dian)池內部的電(dian)(dian)解(jie)液

　　led太陽能路燈撬開膠(jiao)粘的(de)或者熱封的(de)電(dian)池(chi)上蓋(gai)，露出免(mian)維護電(dian)池(chi)的(de)橡膠(jiao)排(pai)氣閥(fa)，小心拆下排(pai)氣閥(fa)，保存好(hao)(hao)，觀(guan)察電(dian)池(chi)內部(bu)情況。給電(dian)池(chi)加含0.1%～0.5%硫(liu)酸的(de)電(dian)解(jie)液，到電(dian)池(chi)上面剛好(hao)(hao)有(you)流動的(de)電(dian)解(jie)液。同(tong)時(shi)，檢查是否由黑色(se)雜質(zhi)，如果有(you)明顯的(de)黑色(se)渾濁(zhuo)雜質(zhi)，說(shuo)明電(dian)池(chi)的(de)正極板已經明顯的(de)軟(ruan)化，電(dian)池(chi)修好(hao)(hao)的(de)可能性(xing)比較小。如果沒有(you)黑色(se)渾濁(zhuo)雜質(zhi)，需要(yao)等待4小時(shi)以(yi)后，水(shui)充分深入電(dian)池(chi)。如果僅僅是因為停(ting)用時(shi)間(jian)較長(chang)而引起(qi)電(dian)池(chi)容量下降，不需要(yao)進(jin)行(xing)本(ben)步(bu)驟操作，應該直接(jie)進(jin)入步(bu)驟3預充電(dian)。

　　3、預充電

　　led太(tai)陽(yang)能(neng)路(lu)燈(deng)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)進行(xing)恒壓(ya)限流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。就是開(kai)始的(de)時候(hou)，采(cai)用0.1C～0.25C電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，到(dao)(dao)16.2V以后，通過降(jiang)(jiang)低(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)方(fang)法(fa)，維(wei)持(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，一直到(dao)(dao)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流下降(jiang)(jiang)到(dao)(dao)0.03C的(de)時候(hou)，停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。注意，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)時候(hou)，會有(you)(you)氣體帶(dai)著電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)液(ye)從排氣孔中溢(yi)出，為了不污染環境(jing)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)應該(gai)(gai)放(fang)到(dao)(dao)耐酸(suan)的(de)容(rong)器中。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)以后，觀(guan)察電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內部是否還有(you)(you)游離酸(suan)，如(ru)果沒有(you)(you)，需要補0.1%的(de)硫酸(suan)溶液(ye)，一直到(dao)(dao)出現少許游離酸(suan)。如(ru)果每個單格里都(dou)有(you)(you)游離酸(suan)，用傾倒和(he)吸(xi)管吸(xi)出可見到(dao)(dao)的(de)游離酸(suan)，使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)處于準貧(pin)液(ye)狀態(tai)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)結束以后，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)靜止半(ban)小時以后，測量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)開(kai)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)應該(gai)(gai)在12V以上，如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)低(di)于12V，特別是低(di)于10.8V，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)可能(neng)有(you)(you)內短(duan)路(lu)，該(gai)(gai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)已經沒有(you)(you)維(wei)修(xiu)價值。

　　4、修復

　　led太陽能路燈連接修(xiu)復儀(yi)的正負(fu)輸出(chu)到電(dian)池的正負(fu)極柱上，開啟修(xiu)復儀(yi)，對電(dian)池進(jin)行修(xiu)復。首次修(xiu)復時(shi)間應該不(bu)低(di)于48小時(shi)。

　　5、容量測試

　　led太陽(yang)能(neng)路燈給電(dian)池(chi)按(an)照0.1C電(dian)流放電(dian)，記錄放電(dian)時(shi)間。其放電(dian)電(dian)流乘以時(shi)間的(de)小時(shi)數，就是電(dian)池(chi)修(xiu)(xiu)(xiu)(xiu)復的(de)容(rong)(rong)(rong)量。如(ru)果(guo)電(dian)池(chi)容(rong)(rong)(rong)量達到(dao)到(dao)標稱容(rong)(rong)(rong)量的(de)70％以上，結束修(xiu)(xiu)(xiu)(xiu)復。如(ru)果(guo)容(rong)(rong)(rong)量沒有達到(dao)70％的(de)標稱容(rong)(rong)(rong)量，繼續(xu)按(an)照步驟3充電(dian)。充電(dian)以后繼續(xu)修(xiu)(xiu)(xiu)(xiu)復，一(yi)(yi)般，超(chao)期(qi)存貯一(yi)(yi)年的(de)電(dian)池(chi)需要進行二次修(xiu)(xiu)(xiu)(xiu)復，才可(ke)以恢復到(dao)超(chao)期(qi)存貯以前的(de)狀態。
