    目前，車用(yong)(yong)蓄電池(chi)大(da)多是干(gan)荷式(shi)蓄電池(chi)。其優點是添加電解(jie)液后不充電，30至40分鐘之(zhi)后汽車也可啟動。一些車主不理解(jie)干(gan)荷式(shi)蓄電池(chi)的工作原理，不會維護，使蓄電池(chi)壽(shou)命(ming)大(da)為縮短。正確選擇(ze)和使用(yong)(yong)蓄電池(chi)可從十(shi)個(ge)方面著(zhu)手。

    買蓄電(dian)池(chi)時(shi)看(kan)清上面的(de)(de)字母(mu)，凡(fan)帶有QA字母(mu)的(de)(de)為干(gan)荷式蓄電(dian)池(chi)。

    1.先將電(dian)(dian)解液(ye)搖勻再向蓄電(dian)(dian)池(chi)中添(tian)加。操作(zuo)時請(qing)戴手套，注意不要將電(dian)(dian)解液(ye)灑(sa)在手上或衣服上。

    2.沒有標志(zhi)線的蓄(xu)電池，電解(jie)液高過(guo)極板10至15毫米即可；有兩條紅(hong)線的蓄(xu)電池，電解(jie)液不得(de)超過(guo)上紅(hong)線。

    3.有人認為電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)越(yue)多(duo)電(dian)(dian)(dian)(dian)(dian)(dian)量越(yue)大，這(zhe)是錯誤的想(xiang)法。汽(qi)車在高速行駛時，發電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓大于蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)壓，開始給(gei)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)體積膨脹(zhang)，如果電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)太滿會從蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)蓋小孔中溢出(chu)。電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)導電(dian)(dian)(dian)(dian)(dian)(dian)，一旦(dan)流到蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)正、負兩極之(zhi)間，就會形成回路自(zi)放電(dian)(dian)(dian)(dian)(dian)(dian)。汽(qi)車不能啟動(dong)，并(bing)使蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)壽命縮(suo)短。遇此情況就應用棉絲將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)擦掉(diao)，或用開水沖洗(xi)擦凈。

    4.加電(dian)解液時(shi)不(bu)(bu)(bu)要讓其他物品掉進蓄電(dian)池(chi)(chi)內。如(ru)有東西不(bu)(bu)(bu)慎掉入(ru)，千(qian)萬不(bu)(bu)(bu)能用(yong)金屬物質去(qu)撈，應(ying)用(yong)木棒夾出(chu)雜(za)質；如(ru)用(yong)鐵絲(si)或銅絲(si)去(qu)撈，金屬分(fen)子會在(zai)硫(liu)酸的腐蝕下進入(ru)蓄電(dian)池(chi)(chi)形成自放電(dian)，損壞蓄電(dian)池(chi)(chi)。

    5.定期檢查蓄電(dian)(dian)池(chi)蓋上的(de)小孔是否通氣。倘若小孔被堵(du)，產生的(de)氣體就排不出(chu)去，電(dian)(dian)解液膨脹(zhang)時會把蓄電(dian)(dian)池(chi)外殼撐破，從而減少蓄電(dian)(dian)池(chi)的(de)壽命。

    6.定期檢查電(dian)解(jie)液(ye)的液(ye)面高(gao)度，液(ye)面高(gao)度下降(jiang)時(shi)及時(shi)添加電(dian)解(jie)液(ye)。

    7.如果車輛長期放(fang)置(zhi)不用，每隔25天應(ying)將(jiang)汽(qi)車發動起來，中(zhong)等轉速運行20分鐘左右。否則，汽(qi)車放(fang)置(zhi)時間太長，將(jiang)難以啟動。

    8.將蓄(xu)電(dian)池(chi)(chi)從汽車上拆(chai)(chai)下時(shi)(shi)，應先拆(chai)(chai)負極(ji)再(zai)拆(chai)(chai)正(zheng)(zheng)極(ji)，裝時(shi)(shi)與此相反。充電(dian)時(shi)(shi)一定要(yao)把蓄(xu)電(dian)池(chi)(chi)蓋(gai)擰下，不能用明(ming)火接近正(zheng)(zheng)在充電(dian)的蓄(xu)電(dian)池(chi)(chi)口(kou)，因為(wei)充電(dian)時(shi)(shi)蓄(xu)電(dian)池(chi)(chi)內產生的氫氣很容易爆燃。

    9.不(bu)要隨(sui)便(bian)給汽車(che)更換比(bi)原蓄(xu)(xu)電池(chi)(chi)容量大的蓄(xu)(xu)電池(chi)(chi)。因為汽車(che)發電機的發電量是固定(ding)的。如換了(le)容量大的蓄(xu)(xu)電池(chi)(chi)，會使新(xin)蓄(xu)(xu)電池(chi)(chi)充不(bu)足電，汽車(che)不(bu)能順(shun)利啟動，而且(qie)蓄(xu)(xu)電池(chi)(chi)長(chang)期(qi)虧電會縮(suo)短(duan)壽命。

    10.啟動汽(qi)車(che)時(shi)每次啟動時(shi)間不(bu)應超過3至(zhi)5秒(miao)，再次啟動間隔時(shi)間不(bu)少于15秒(miao)。
