18650電池充不進電池有很多情況，不同的問題需要采取相應的修復方法，才能很好的解決18650電池充不進電的問題。那么電池充不進電都有哪些情況，又有哪些解決的辦法呢？

1、導致18650電池充不進電的外(wai)部原因

（1）18650電(dian)池充電(dian)器問題(ti)

1）充電(dian)器故障，即(ji)充電(dian)器由于使用一定時間后，出(chu)現故障，導致充電(dian)器損壞，這樣自然充不進電(dian)了(le)，這樣的(de)話，建議(yi)更換充電(dian)器。

2）充電(dian)(dian)(dian)(dian)器不匹配，這個可能(neng)是充電(dian)(dian)(dian)(dian)器充電(dian)(dian)(dian)(dian)提供(gong)的電(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)壓(ya)過(guo)低，無(wu)法對電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)；或是電(dian)(dian)(dian)(dian)壓(ya)過(guo)高，電(dian)(dian)(dian)(dian)流過(guo)大(da)，導致(zhi)充電(dian)(dian)(dian)(dian)時電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)芯損壞，導致(zhi)無(wu)法充電(dian)(dian)(dian)(dian)。

（2）環(huan)境因素影響(xiang)電池充電

1）充(chong)(chong)(chong)電(dian)時在過低的溫(wen)(wen)度(du)(du)環境(jing)下充(chong)(chong)(chong)電(dian)，18650電(dian)池(chi)有低溫(wen)(wen)充(chong)(chong)(chong)放(fang)電(dian)的限制要求，可(ke)能是因(yin)為(wei)充(chong)(chong)(chong)電(dian)環境(jing)溫(wen)(wen)度(du)(du)過低，導致無(wu)法(fa)充(chong)(chong)(chong)電(dian)。這(zhe)個可(ke)以將電(dian)池(chi)放(fang)到其規定的充(chong)(chong)(chong)電(dian)溫(wen)(wen)度(du)(du)范圍內進行充(chong)(chong)(chong)電(dian)，一般就可(ke)以。如(ru)果不行，估(gu)計是電(dian)池(chi)在過低溫(wen)(wen)度(du)(du)下時間過久，導致電(dian)芯出(chu)問題。這(zhe)樣就只能換電(dian)池(chi)了(le)。

2）充電(dian)(dian)時(shi)所(suo)在溫(wen)(wen)度(du)環(huan)境過高(gao)，一般18650電(dian)(dian)池會有(you)溫(wen)(wen)度(du)保護機制(zhi)，溫(wen)(wen)度(du)過高(gao)觸發(fa)保護，導(dao)致(zhi)無法(fa)充電(dian)(dian)，可(ke)以將電(dian)(dian)池放(fang)到允許充電(dian)(dian)溫(wen)(wen)度(du)范(fan)圍內，如果不行，有(you)可(ke)能是因為(wei)由于電(dian)(dian)池在高(gao)溫(wen)(wen)運行時(shi)，導(dao)致(zhi)電(dian)(dian)池電(dian)(dian)芯內的(de)隔膜擊(ji)穿短(duan)路或其他(ta)化學反(fan)應，導(dao)致(zhi)電(dian)(dian)池無法(fa)使(shi)用。這個就只能更換電(dian)(dian)池了。

3）充(chong)電(dian)(dian)(dian)(dian)環境(jing)濕度過高，導(dao)致電(dian)(dian)(dian)(dian)路(lu)故(gu)障或短路(lu)，現將電(dian)(dian)(dian)(dian)池(chi)和充(chong)電(dian)(dian)(dian)(dian)器干燥(zao)，在進行充(chong)電(dian)(dian)(dian)(dian)，如果不可(ke)以(yi)，就(jiu)要分別檢(jian)查(cha)是充(chong)電(dian)(dian)(dian)(dian)器已損壞還(huan)是電(dian)(dian)(dian)(dian)池(chi)已損壞，并(bing)做出相應的更換(huan)就(jiu)可(ke)以(yi)。

2、18650電(dian)池(chi)自(zi)身原因

1）不管是(shi)哪(na)個廠家生產(chan)的電(dian)池(chi)(chi)電(dian)芯，都會有自放(fang)電(dian)，電(dian)池(chi)(chi)使用到一定(ding)的循環周期后，自放(fang)電(dian)會變大，慢(man)慢(man)的會造成電(dian)池(chi)(chi)內部短(duan)路，通常比(bi)較多的是(shi)電(dian)池(chi)(chi)隔(ge)膜(mo)被擊(ji)穿導致。這(zhe)樣的，如果(guo)對電(dian)池(chi)(chi)知識比(bi)較了(le)解的，可以自行更(geng)換(huan)問(wen)題電(dian)芯就可。非專業人士，不建議(yi)做。

2）電(dian)池(chi)組裝時，電(dian)芯的(de)一(yi)致性(xing)(xing)誤(wu)(wu)差過大(da)，剛開(kai)始使用(yong)時，問題不大(da)，但一(yi)定使用(yong)循環次數(shu)后(hou)，這個(ge)誤(wu)(wu)差會(hui)導致電(dian)池(chi)更電(dian)芯的(de)使用(yong)性(xing)(xing)能，最終有可能多數(shu)或全部(bu)報廢。這個(ge)也只能更換電(dian)池(chi)。

3）電(dian)池(chi)極耳焊(han)接(jie)脫落，這個有兩(liang)方面的(de)原因，一(yi)個是使用(yong)過程(cheng)中的(de)不(bu)小心造成的(de)單個或(huo)(huo)多個電(dian)芯極耳焊(han)接(jie)脫落，另(ling)一(yi)個是電(dian)池(chi)廠家在生產電(dian)芯的(de)時候，會(hui)有偶(ou)爾出現焊(han)接(jie)不(bu)良的(de)可能(neng)，電(dian)池(chi)使用(yong)過程(cheng)中的(de)電(dian)流會(hui)有瞬時大電(dian)流放電(dian)，可能(neng)會(hui)會(hui)導(dao)致(zhi)焊(han)接(jie)不(bu)良的(de)電(dian)芯極耳脫焊(han)或(huo)(huo)電(dian)芯隔膜擊穿，導(dao)致(zhi)斷(duan)路或(huo)(huo)是短路。這個非專業(ye)人(ren)士，建議購買新的(de)電(dian)池(chi)。

4）電池保護板的故障，很有可能是因為使用不注意，導致電池保護板電路故障或軟件故障，這個基本是修不好的，建議換電池。當然如果是專業人士，有相應的檢修工具，也可以自己購買合適的電池保護板進行更換。
