正確答案:

(1)蓄電池在放電后,應在最短的時間內進行充電,以免極板頂部產生白色的硫酸鉛層,稱為硫酸化。

(2)蓄電池的注液氣蓋的氣孔應保持暢通,充電時擰開,結束后蓋緊。

(3)應經常檢查蓄電池的電解液面的高度。

(4)已充電而擱置未用的蓄電池,每月最少要充電一次。

(5)經常保持清潔。定期洗刷外露表面、通氣蓋和接線柱,清洗時勿使清洗液和雜物進入蓄電池。

(6)蓄電池如經常充電不足、長期用小電源放電、過量放電或放電后未及時充電,均會促使極板硫酸化,影響正常充、放電性能。

(7)蓄電池的充放電程度,可使用比重計測量電解液的比重或用放電儀測量端電壓來確定。

(8)在寒冷地區使用時,注意保溫,并適當增加電解液密度,以防止因密度下降而凍結,在環.境溫度低于一40‘C時,密度增加至1.30~1. 32。

(9)當隔板損壞或底部沉淀物積聚過多,均可使蓄電池板極短路,應予修理。正、負極活性物質過多而引起電壓和容量下降時,應更換新的極板。
