人們在使用鉛酸蓄電池的過程(cheng)中常常會陷入誤(wu)區(qu)當中，以(yi)下就介紹(shao)常見的幾種使(shi)用(yong)誤(wu)區(qu)，給(gei)大家(jia)借鑒避免。

鉛酸蓄電池電荷容量與發(fa)動機不匹配(pei)

鉛酸蓄電池并聯混用

有些駕駛員在起動發動機時，因原有蓄電池存電不足，就并聯上一只充足電的蓄電池共同使用。實際上并聯后充足電的蓄電池會以很大的充電電流向存電不足的蓄電池充電(dian)(dian)，極易造成極板活性物質脫落(luo)，影響(xiang)其使用壽命。同時蓄電(dian)(dian)池并(bing)聯后(hou)并(bing)不能(neng)提供給(gei)起(qi)動(dong)(dong)機很大的(de)起(qi)動(dong)(dong)電(dian)(dian)流，更不利于發動(dong)(dong)機的(de)起(qi)動(dong)(dong)。正(zheng)確的(de)方法應當是把存電(dian)(dian)不足的(de)蓄電(dian)(dian)池拆下，換上充足電(dian)(dian)的(de)蓄電(dian)(dian)池，然后(hou)再起(qi)動(dong)(dong)發動(dong)(dong)機。

鉛酸蓄電池串聯混用

在(zai)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)使用中，有時會出(chu)現新(xin)、舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串(chuan)聯使用的(de)現象，殊(shu)不(bu)知(zhi)，這種(zhong)做法會縮短(duan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)使用壽(shou)命。因為新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內(nei)的(de)化學反應物(wu)質(zhi)較(jiao)(jiao)多，端電(dian)(dian)(dian)(dian)(dian)(dian)壓較(jiao)(jiao)高(gao)，內(nei)阻(zu)較(jiao)(jiao)小（12V新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內(nei)阻(zu)只有0.015-0.018Ω）；而舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)壓較(jiao)(jiao)低(di)，內(nei)阻(zu)較(jiao)(jiao)大(da)（12V舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)內(nei)阻(zu)在(zai)0.085Ω以上）。如果將新(xin)、舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)串(chuan)聯混用，那(nei)么在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)狀態下，舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)兩端的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓將高(gao)于(yu)新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)兩端的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓，結(jie)果造(zao)成新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)尚未充(chong)足而舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)早(zao)已(yi)過高(gao)；在(zai)放電(dian)(dian)(dian)(dian)(dian)(dian)狀態下，由(you)于(yu)新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷容量(liang)比舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷容量(liang)大(da)，結(jie)果造(zao)成舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)過量(liang)放電(dian)(dian)(dian)(dian)(dian)(dian)，甚至造(zao)成舊蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)反極。因此對蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)決不(bu)能新(xin)、舊混用。

另外，不同電荷容量的鉛酸蓄電池也不能串聯混用，因為兩種電荷容量不同的蓄電池串聯使用時，往往會使電荷容量小的蓄電池過(guo)量充電(dian)或放電(dian)，縮短其使用壽(shou)命(ming)。
