1、清理

　　維護電(dian)池(chi)以前，首先要清(qing)理led被修電(dian)池(chi)外表的灰(hui)塵，清(qing)除端子上面(mian)的沾污和銹蝕(shi)。

　　2、打(da)開排氣閥(fa)，觀察電池內(nei)部的電解液

　　led太陽(yang)能(neng)路燈撬開膠粘的(de)(de)或者熱封的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)上(shang)蓋，露出免維護電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)橡膠排(pai)氣閥(fa)，小心(xin)拆下排(pai)氣閥(fa)，保(bao)存好(hao)，觀察(cha)電(dian)(dian)(dian)池(chi)(chi)(chi)內部情況。給電(dian)(dian)(dian)池(chi)(chi)(chi)加含0.1%～0.5%硫酸(suan)的(de)(de)電(dian)(dian)(dian)解液，到(dao)電(dian)(dian)(dian)池(chi)(chi)(chi)上(shang)面剛好(hao)有(you)流動的(de)(de)電(dian)(dian)(dian)解液。同(tong)時，檢查(cha)是否由黑(hei)色雜(za)質，如(ru)果有(you)明顯的(de)(de)黑(hei)色渾(hun)(hun)濁(zhuo)雜(za)質，說明電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)正(zheng)極板已經明顯的(de)(de)軟化，電(dian)(dian)(dian)池(chi)(chi)(chi)修好(hao)的(de)(de)可能(neng)性比較(jiao)小。如(ru)果沒(mei)有(you)黑(hei)色渾(hun)(hun)濁(zhuo)雜(za)質，需(xu)要等待4小時以后，水充分深(shen)入(ru)電(dian)(dian)(dian)池(chi)(chi)(chi)。如(ru)果僅(jin)僅(jin)是因為停用時間較(jiao)長而引起電(dian)(dian)(dian)池(chi)(chi)(chi)容量下降，不需(xu)要進行本步驟(zou)(zou)操(cao)作，應該直接進入(ru)步驟(zou)(zou)3預充電(dian)(dian)(dian)。

　　3、預充電

　　led太陽(yang)能路燈(deng)對電(dian)(dian)池(chi)(chi)(chi)進行(xing)恒壓限(xian)流充(chong)(chong)(chong)電(dian)(dian)。就是(shi)開始(shi)的(de)時候(hou)，采用(yong)0.1C～0.25C電(dian)(dian)流充(chong)(chong)(chong)電(dian)(dian)，到16.2V以(yi)(yi)后，通過降低(di)電(dian)(dian)流的(de)方法，維持充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)壓，一(yi)直到充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流下降到0.03C的(de)時候(hou)，停止充(chong)(chong)(chong)電(dian)(dian)。注意，充(chong)(chong)(chong)電(dian)(dian)的(de)時候(hou)，會有(you)(you)(you)(you)氣(qi)體帶著電(dian)(dian)解液(ye)從排(pai)氣(qi)孔中(zhong)溢出(chu)，為(wei)了不污染環境(jing)，電(dian)(dian)池(chi)(chi)(chi)應(ying)該放到耐酸的(de)容器(qi)中(zhong)。充(chong)(chong)(chong)電(dian)(dian)以(yi)(yi)后，觀察電(dian)(dian)池(chi)(chi)(chi)內部是(shi)否還有(you)(you)(you)(you)游(you)離(li)酸，如(ru)果(guo)沒有(you)(you)(you)(you)，需要補0.1%的(de)硫酸溶液(ye)，一(yi)直到出(chu)現(xian)少許游(you)離(li)酸。如(ru)果(guo)每個單(dan)格里都有(you)(you)(you)(you)游(you)離(li)酸，用(yong)傾(qing)倒和(he)吸(xi)管吸(xi)出(chu)可見到的(de)游(you)離(li)酸，使電(dian)(dian)池(chi)(chi)(chi)處(chu)于(yu)(yu)準貧液(ye)狀態。充(chong)(chong)(chong)電(dian)(dian)結束以(yi)(yi)后，電(dian)(dian)池(chi)(chi)(chi)靜止半小時以(yi)(yi)后，測(ce)量電(dian)(dian)池(chi)(chi)(chi)的(de)開路電(dian)(dian)壓，電(dian)(dian)壓應(ying)該在12V以(yi)(yi)上，如(ru)果(guo)電(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)壓低(di)于(yu)(yu)12V，特別(bie)是(shi)低(di)于(yu)(yu)10.8V，電(dian)(dian)池(chi)(chi)(chi)可能有(you)(you)(you)(you)內短(duan)路，該電(dian)(dian)池(chi)(chi)(chi)已(yi)經沒有(you)(you)(you)(you)維修價值。

　　4、修復

　　led太陽(yang)能(neng)路(lu)燈連接修復(fu)(fu)儀(yi)的正負輸出到電池的正負極(ji)柱(zhu)上，開啟修復(fu)(fu)儀(yi)，對電池進行修復(fu)(fu)。首次修復(fu)(fu)時間應該不低于48小時。

　　5、容量測試

　　led太(tai)陽能路燈給電(dian)池按照0.1C電(dian)流(liu)放(fang)(fang)電(dian)，記錄放(fang)(fang)電(dian)時間(jian)。其放(fang)(fang)電(dian)電(dian)流(liu)乘以(yi)時間(jian)的(de)小時數，就是電(dian)池修(xiu)(xiu)復(fu)的(de)容量(liang)(liang)。如(ru)果電(dian)池容量(liang)(liang)達到(dao)到(dao)標稱(cheng)容量(liang)(liang)的(de)70％以(yi)上(shang)，結(jie)束修(xiu)(xiu)復(fu)。如(ru)果容量(liang)(liang)沒有達到(dao)70％的(de)標稱(cheng)容量(liang)(liang)，繼續按照步驟3充電(dian)。充電(dian)以(yi)后繼續修(xiu)(xiu)復(fu)，一般，超期(qi)存貯一年的(de)電(dian)池需要(yao)進行二(er)次修(xiu)(xiu)復(fu)，才可以(yi)恢(hui)復(fu)到(dao)超期(qi)存貯以(yi)前(qian)的(de)狀(zhuang)態。
