電(dian)池(chi)(chi)(chi)的(de)(de)修(xiu)復(fu)雖然沒(mei)有成為一個行業(ye)，但是電(dian)池(chi)(chi)(chi)修(xiu)復(fu)工作一直是存在的(de)(de)。不少(shao)電(dian)池(chi)(chi)(chi)制造(zao)商(shang)對保用期以內(nei)的(de)(de)返退電(dian)池(chi)(chi)(chi)采取(qu)"修(xiu)舊利(li)舊"的(de)(de)發生(sheng)，把通(tong)過維修(xiu)的(de)(de)電(dian)池(chi)(chi)(chi)重新提供給用戶，以提高電(dian)池(chi)(chi)(chi)的(de)(de)有效使用壽(shou)命，降(jiang)低報廢(fei)率，減少(shao)電(dian)池(chi)(chi)(chi)制造(zao)商(shang)的(de)(de)部分理索賠的(de)(de)損(sun)失。這些修(xiu)復(fu)方法為：

1、重新配組
電池返退以后，電池制造商重新進行(xing)充放(fang)電(dian)檢驗，在(zai)檢驗中往(wang)往(wang)會發(fa)現(xian)有(you)50％以上的電(dian)池(chi)不符(fu)合返(fan)退條件的電(dian)池(chi)。其原因也就是在(zai)串連電(dian)池(chi)組(zu)中，個別的電(dian)池(chi)落后(hou)形成整(zheng)(zheng)組(zu)電(dian)池(chi)功能下降而引起整(zheng)(zheng)組(zu)返(fan)退。

2、補水
鑒于(yu)部分電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)制造(zao)商(shang)還是采用(yong)(yong)(yong)低(di)銻合(he)金的(de)(de)板(ban)(ban)柵，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)失(shi)水電(dian)(dian)(dian)(dian)平(ping)比(bi)較低(di)，加(jia)(jia)上最高充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)高于(yu)析氫電(dian)(dian)(dian)(dian)壓(ya)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)失(shi)水更(geng)加(jia)(jia)嚴重(zhong)，形成(cheng)(cheng)了(le)(le)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)第一(yi)位的(de)(de)失(shi)效(xiao)原因(yin)。對(dui)此，一(yi)些電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)制造(zao)商(shang)有(you)(you)意的(de)(de)改造(zao)了(le)(le)蓋板(ban)(ban)，并且在(zai)排(pai)氣閥下部設立(li)了(le)(le)螺(luo)裝結構，為(wei)打(da)開電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)形成(cheng)(cheng)了(le)(le)方便(bian)條件(jian)，這(zhe)樣(yang)，有(you)(you)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)制造(zao)商(shang)開展電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)補水工作。對(dui)使(shi)(shi)用(yong)(yong)(yong)了(le)(le)半年的(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進(jin)行一(yi)次(ci)補水，可(ke)以(yi)延長電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命，延長時間平(ping)均達到3個(ge)月以(yi)上。應該注意的(de)(de)是，每(mei)次(ci)補水以(yi)后，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)都利用(yong)(yong)(yong)處于(yu)過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)狀態把電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)由"準貧液"轉為(wei)"貧液"狀態，而(er)這(zhe)個(ge)過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)對(dui)提高電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量是有(you)(you)好處的(de)(de)。

3、消除硫化
采用(yong)(yong)專(zhuan)門的(de)設備，對電(dian)(dian)池進行(xing)消除(chu)硫化的(de)處理。這里主要有2種(zhong)方法(fa)，其一就是高(gao)電(dian)(dian)壓大(da)電(dian)(dian)流脈沖充電(dian)(dian)，通過負阻擊穿消除(chu)硫化。這種(zhong)方法(fa)速(su)度(du)快(kuai)，見效快(kuai)，但(dan)是對電(dian)(dian)池的(de)壽命影(ying)響(xiang)比較(jiao)大(da)。另外的(de)方法(fa)就是采用(yong)(yong)小電(dian)(dian)流頻率高(gao)達8KHz以(yi)(yi)(yi)(yi)上(shang)，利用(yong)(yong)大(da)結(jie)晶(jing)諧振的(de)方法(fa)來溶解(jie)，這種(zhong)方法(fa)修(xiu)復(fu)(fu)比較(jiao)慢，修(xiu)復(fu)(fu)效果也比較(jiao)好，但(dan)是，修(xiu)復(fu)(fu)時(shi)間比較(jiao)長(chang)，往往在120小時(shi)以(yi)(yi)(yi)(yi)上(shang)。實際測試(shi)數據表明，對于補(bu)水(shui)以(yi)(yi)(yi)(yi)后(hou)沒有達到(dao)60％補(bu)充容(rong)(rong)量的(de)電(dian)(dian)池進行(xing)除(chu)硫處理，還有約(yue)2/3的(de)電(dian)(dian)池可以(yi)(yi)(yi)(yi)達到(dao)60％以(yi)(yi)(yi)(yi)上(shang)的(de)容(rong)(rong)量，甚(shen)至(zhi)還有35％以(yi)(yi)(yi)(yi)上(shang)的(de)電(dian)(dian)池的(de)容(rong)(rong)量可以(yi)(yi)(yi)(yi)達到(dao)80％以(yi)(yi)(yi)(yi)上(shang)的(de)容(rong)(rong)量。

4、采(cai)取類(lei)似電(dian)霸、保護器(qi)類(lei)的脈沖發生器(qi)并聯在(zai)電(dian)池(chi)上，對(dui)電(dian)池(chi)進行(xing)脈沖維護。這種方法(fa)對(dui)修復電(dian)池(chi)比較慢，但是(shi)由于(yu)(yu)長(chang)年在(zai)維修，所(suo)以，如果沒有(you)過(guo)放電(dian)，對(dui)于(yu)(yu)連續使用的電(dian)池(chi)來說，往(wang)往(wang)是(shi)徹底(di)消除了電(dian)池(chi)硫化的可能性(xing)。

5、綜合修復方法
如果對電池采用定期檢驗，及時除硫和補水，單只電池充電、重新配組。采取這些做法以后，電池的(de)(de)平均壽命會大(da)(da)大(da)(da)提高。定期(qi)檢(jian)修(xiu)的(de)(de)意(yi)義比(bi)(bi)較大(da)(da)，不要(yao)等電(dian)池(chi)(chi)由于失(shi)水和硫化(hua)的(de)(de)影響，損(sun)傷正(zheng)(zheng)極板(ban)以后再修(xiu)復。這樣，可(ke)以大(da)(da)大(da)(da)延長電(dian)池(chi)(chi)的(de)(de)壽命。而(er)一旦電(dian)池(chi)(chi)出現嚴重的(de)(de)失(shi)水和硫化(hua)以后，對(dui)(dui)正(zheng)(zheng)極板(ban)的(de)(de)損(sun)傷相對(dui)(dui)也比(bi)(bi)較大(da)(da)。所以，應該在對(dui)(dui)正(zheng)(zheng)極板(ban)損(sun)傷以前久對(dui)(dui)電(dian)池(chi)(chi)進行適當的(de)(de)維(wei)修(xiu)。采取防患(huan)于未(wei)然的(de)(de)檢(jian)修(xiu)的(de)(de)方法比(bi)(bi)亡羊(yang)補(bu)牢的(de)(de)方法更加有(you)效。
