當電動叉車蓄電(dian)(dian)(dian)池(chi)虧電(dian)(dian)(dian)時(shi)，有必要及時(shi)補(bu)充充電(dian)(dian)(dian)。如果光線暗淡(dan)，喇叭聲音嘶啞(ya)，啟動(dong)不敏感(gan)，說明電(dian)(dian)(dian)池(chi)嚴重缺電(dian)(dian)(dian)，叉(cha)車(che)電(dian)(dian)(dian)池(chi)板容(rong)易硫化(hua)，從而降低(di)電(dian)(dian)(dian)池(chi)容(rong)量(liang)，增加內阻，降低(di)輸出電(dian)(dian)(dian)流。這時(shi)應及時(shi)用充電(dian)(dian)(dian)機對蓄電(dian)(dian)(dian)池(chi)進行補(bu)充充電(dian)(dian)(dian)，直(zhi)至電(dian)(dian)(dian)解液中產生(sheng)大量(liang)氣泡為(wei)止。

當(dang)電(dian)池(chi)長時(shi)間不(bu)使用時(shi)，應定(ding)期充電(dian)和維護。在(zai)車(che)輛儲(chu)存(cun)(cun)期間，電(dian)池(chi)一般應集中(zhong)在(zai)電(dian)池(chi)室內，并由專人進行維護。須知，蓄(xu)電(dian)池(chi)都(dou)存(cun)(cun)在(zai)一個內部自(zi)放電(dian)的問題，每(mei)(mei)天自(zi)放電(dian)量(liang)約2％，因(yin)此，蓄(xu)電(dian)池(chi)必須有專人專室保(bao)管，定(ding)時(shi)檢查(cha)，每(mei)(mei)月至少補充充電(dian)1次。

檢(jian)(jian)查保養(yang)時(shi)，嚴格(ge)按(an)操作規(gui)程進行平時(shi)在檢(jian)(jian)查維護保養(yang)時(shi)，絕(jue)對禁止用金(jin)屬絲或金(jin)屬棒來測(ce)量電解液液面，也(ye)不要隨(sui)便(bian)將扳手、螺絲刀等金(jin)屬工具放在電動叉車(che)蓄(xu)電池(chi)上，否(fou)則(ze)很(hen)容易造成蓄(xu)電池(chi)短(duan)路。

另外，使用多個串聯電池充電或使用時，盡量串聯使用容量相同的電池。不要使用容量大，小或新舊搭配方法。不同容量的電動叉車蓄電(dian)池串聯時，較小的蓄電(dian)池會(hui)過充或過放，導致電(dian)池板(ban)(ban)(ban)的活性物質(zhi)脫落，較大的電(dian)池板(ban)(ban)(ban)會(hui)過充，從而(er)降低電(dian)池板(ban)(ban)(ban)的硫化容量。
