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(chong)電(dian)，極易造成極板活性物(wu)質脫(tuo)落(luo)，影響其使(shi)用(yong)壽命。同時(shi)蓄電(dian)池并聯后并不能提供給(gei)起(qi)動(dong)機很大的(de)(de)起(qi)動(dong)電(dian)流，更(geng)不利于發(fa)動(dong)機的(de)(de)起(qi)動(dong)。正確的(de)(de)方法應當是把存電(dian)不足的(de)(de)蓄電(dian)池拆下，換上(shang)充(chong)足電(dian)的(de)(de)蓄電(dian)池，然后再起(qi)動(dong)發(fa)動(dong)機。

鉛酸蓄電池串聯混用

在(zai)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)使用中，有時(shi)會出(chu)現新(xin)、舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)串聯(lian)使用的(de)現象，殊不知，這種(zhong)做法(fa)會縮短(duan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)使用壽命。因為(wei)新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內(nei)的(de)化(hua)學反(fan)應物質較多，端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較高(gao)(gao)，內(nei)阻較小（12V新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內(nei)阻只有0.015-0.018Ω）；而(er)(er)舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較低，內(nei)阻較大（12V舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)內(nei)阻在(zai)0.085Ω以上）。如果將(jiang)新(xin)、舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)串聯(lian)混用，那(nei)么在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態下(xia)(xia)，舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)兩端(duan)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓將(jiang)高(gao)(gao)于新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)兩端(duan)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，結果造成新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)尚未充(chong)足(zu)而(er)(er)舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)早已過高(gao)(gao)；在(zai)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態下(xia)(xia)，由于新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量比舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量大，結果造成舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)過量放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，甚至造成舊(jiu)(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)反(fan)極。因此對蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)決不能(neng)新(xin)、舊(jiu)(jiu)(jiu)(jiu)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)量充電或放電，縮短其使用壽(shou)命(ming)。
