人們在使用鉛酸蓄電池的(de)過程(cheng)中(zhong)常常會陷入誤區當中(zhong)，以下就介紹常見的(de)幾種使用誤區，給大家借鑒(jian)避(bi)免。

鉛酸蓄電池電荷容量與發動(dong)機不匹配

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(qi)使用壽(shou)命。同(tong)時蓄電(dian)(dian)池(chi)并(bing)聯后(hou)并(bing)不(bu)能提供給起動(dong)(dong)(dong)機(ji)很(hen)大的起動(dong)(dong)(dong)電(dian)(dian)流，更(geng)不(bu)利于發(fa)動(dong)(dong)(dong)機(ji)的起動(dong)(dong)(dong)。正確的方法應當是把存電(dian)(dian)不(bu)足(zu)的蓄電(dian)(dian)池(chi)拆下(xia)，換上(shang)充足(zu)電(dian)(dian)的蓄電(dian)(dian)池(chi)，然后(hou)再起動(dong)(dong)(dong)發(fa)動(dong)(dong)(dong)機(ji)。

鉛酸蓄電池串聯混用

在(zai)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使(shi)用(yong)(yong)中，有時(shi)會出現(xian)新(xin)、舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)串聯使(shi)用(yong)(yong)的(de)(de)(de)現(xian)象(xiang)，殊不知，這種做(zuo)法會縮短(duan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)使(shi)用(yong)(yong)壽(shou)命(ming)。因(yin)為新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內(nei)(nei)(nei)的(de)(de)(de)化學(xue)反應(ying)物(wu)質較(jiao)(jiao)多(duo)，端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較(jiao)(jiao)高，內(nei)(nei)(nei)阻較(jiao)(jiao)小（12V新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)內(nei)(nei)(nei)阻只有0.015-0.018Ω）；而舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較(jiao)(jiao)低(di)，內(nei)(nei)(nei)阻較(jiao)(jiao)大（12V舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)內(nei)(nei)(nei)阻在(zai)0.085Ω以上(shang)）。如(ru)果(guo)將新(xin)、舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)串聯混用(yong)(yong)，那么在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態下(xia)，舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)兩端的(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓將高于新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)兩端的(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，結(jie)果(guo)造成(cheng)新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)尚未充(chong)足而舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)早已過高；在(zai)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態下(xia)，由于新(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷容量比舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷容量大，結(jie)果(guo)造成(cheng)舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過量放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，甚至造成(cheng)舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)反極。因(yin)此對蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)決不能(neng)新(xin)、舊(jiu)(jiu)混用(yong)(yong)。

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量充電(dian)或放電(dian)，縮(suo)短其使(shi)用壽命(ming)。
