汽車電(dian)(dian)(dian)(dian)瓶屬(shu)于啟動性蓄電(dian)(dian)(dian)(dian)池。通過鉛(qian)與硫酸(suan)的(de)化學反(fan)應(ying)，達到儲(chu)（放(fang)）電(dian)(dian)(dian)(dian)能的(de)物理作(zuo)用。面(mian)板標注為(wei)(wei)xQWxxA/HxxxA，舉例(li)：6QW55A/H300A，既(ji)為(wei)(wei)：6節(jie)鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)池，電(dian)(dian)(dian)(dian)量55安(an)/時，最大(da)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流300安(an)培(pei)。主要指(zhi)標：電(dian)(dian)(dian)(dian)壓：單位(wei)伏(fu)特(te)（V）鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)池每單節(jie)（格(ge)）2，0伏(fu)特(te)。充電(dian)(dian)(dian)(dian)終止(zhi)電(dian)(dian)(dian)(dian)壓2.17—2.2伏(fu)特(te)，放(fang)電(dian)(dian)(dian)(dian)終止(zhi)電(dian)(dian)(dian)(dian)壓1.75伏(fu)特(te)。電(dian)(dian)(dian)(dian)量單位(wei)為(wei)(wei)安(an)/小時（A/H），常(chang)用多(duo)為(wei)(wei)40—70安(an)/小時。以(yi)(yi)50安(an)/時為(wei)(wei)例(li)：以(yi)(yi)5安(an)培(pei)電(dian)(dian)(dian)(dian)流持續(xu)放(fang)電(dian)(dian)(dian)(dian)，可(ke)連(lian)續(xu)放(fang)電(dian)(dian)(dian)(dian)10小時（也稱十小時放(fang)電(dian)(dian)(dian)(dian)率）。
最大(da)放(fang)電(dian)(dian)電(dian)(dian)流(liu)(liu)：安(an)培。直流(liu)(liu)電(dian)(dian)機(ji)啟動瞬間(jian)(jian)電(dian)(dian)壓降(jiang)(jiang)(jiang)為0，電(dian)(dian)流(liu)(liu)無限大(da)。常見300—400安(an)培之(zhi)間(jian)(jian)。冷車(che)阻(zu)力大(da)，放(fang)電(dian)(dian)（起動）電(dian)(dian)流(liu)(liu)大(da)且時間(jian)(jian)長(chang)，熱車(che)阻(zu)力小，狀態(tai)相反。充放(fang)電(dian)(dian)循環次數，國際暢行標(biao)準多在8000—20000次之(zhi)間(jian)(jian)。隨著充放(fang)電(dian)(dian)次數增加，化(hua)學(xue)活性降(jiang)(jiang)(jiang)低(di)，各(ge)項(xiang)指(zhi)標(biao)降(jiang)(jiang)(jiang)低(di)，就(jiu)離終止(zhi)壽命不遠(yuan)了。電(dian)(dian)解液比(bi)重：以室(shi)溫(wen)(wen)25度，滿電(dian)(dian)為1.28，電(dian)(dian)壓0時，比(bi)重1.0。溫(wen)(wen)度升高，比(bi)重上升，溫(wen)(wen)度降(jiang)(jiang)(jiang)低(di)比(bi)重降(jiang)(jiang)(jiang)低(di)。常見北方寒冷地(di)區啟動困難，與溫(wen)(wen)度有直接(jie)關系。老司機(ji)將(jiang)開水澆(jiao)電(dian)(dian)池(chi)，就(jiu)是(shi)這個道理(li)。長(chang)時間(jian)(jian)不用，電(dian)(dian)解液上下(xia)比(bi)重不同(tong)產(chan)生電(dian)(dian)位差，即造成(cheng)自放(fang)電(dian)(dian)。這就(jiu)是(shi)為什么(me)放(fang)時間(jian)(jian)長(chang)了，電(dian)(dian)池(chi)沒電(dian)(dian)的(de)原因。免(mian)維護電(dian)(dian)池(chi)面板(ban)上的(de)圓形(xing)綠色標(biao)志，就(jiu)是(shi)比(bi)重計(ji)(ji)觀察(cha)窗，比(bi)重高時比(bi)重計(ji)(ji)上浮接(jie)近觀察(cha)窗，綠色標(biao)示(shi)即明顯。當比(bi)重底時，比(bi)重計(ji)(ji)遠(yuan)離觀察(cha)窗，綠色標(biao)示(shi)逐漸變小至消失，提示(shi)您(nin)：電(dian)(dian)量低(di)，該充電(dian)(dian)了。

免維(wei)護(hu)不(bu)(bu)等于(yu)不(bu)(bu)維(wei)護(hu)，經常觀察比重觀察窗(chuang)，可(ke)以防止虧電(dian)(dian)。個人建議：每(mei)年入冬前進行(xing)一(yi)次充電(dian)(dian)機(ji)養護(hu)性充電(dian)(dian)，可(ke)避(bi)免虧電(dian)(dian)，并延長蓄電(dian)(dian)池壽命。當然，養護(hu)充電(dian)(dian)時能夠進行(xing)放電(dian)(dian)（測試電(dian)(dian)量）檢查更好！
