人們在使用鉛酸蓄電池的(de)(de)過(guo)程中常常會陷入誤區(qu)當中，以(yi)下(xia)就介紹常見的(de)(de)幾種使用誤區(qu)，給大家借鑒避免。

鉛酸蓄電池電荷容量與(yu)發動(dong)機不(bu)匹配(pei)

根據發(fa)(fa)(fa)動(dong)(dong)機(ji)類型和使(shi)用條件合(he)理選(xuan)用鉛(qian)酸(suan)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)，是提(ti)高鉛(qian)酸(suan)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)經(jing)(jing)濟性(xing)，延長(chang)其使(shi)用壽命(ming)(ming)的(de)(de)(de)(de)重要途(tu)徑(jing)之一。起動(dong)(dong)機(ji)起動(dong)(dong)發(fa)(fa)(fa)動(dong)(dong)機(ji)時，鉛(qian)酸(suan)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)輸出的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)很(hen)大(da)，在(zai)(zai)一般(ban)情況(kuang)下(xia)為150A-200A，在(zai)(zai)低(di)溫(wen)（-10℃）起動(dong)(dong)時輸出的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)高達250A-300A。如果(guo)(guo)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)與(yu)(yu)(yu)發(fa)(fa)(fa)動(dong)(dong)機(ji)不匹配(pei)，蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)偏小，則在(zai)(zai)起動(dong)(dong)阻力大(da)時，小電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)的(de)(de)(de)(de)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)在(zai)(zai)劇烈(lie)放電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)情況(kuang)下(xia)，勢必加速單(dan)位時間內活性(xing)物(wu)(wu)質(zhi)(zhi)與(yu)(yu)(yu)硫酸(suan)的(de)(de)(de)(de)反應(ying)，使(shi)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)度升高，極板因過負荷(he)(he)(he)(he)而彎曲(qu)，結果(guo)(guo)造成活性(xing)物(wu)(wu)質(zhi)(zhi)大(da)量(liang)(liang)脫落，極板早期(qi)損壞，從而使(shi)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)壽命(ming)(ming)大(da)大(da)縮短。如果(guo)(guo)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)偏大(da)，雖然不會(hui)發(fa)(fa)(fa)生上述問題(ti)，但不能充(chong)分利(li)用其活性(xing)物(wu)(wu)質(zhi)(zhi)，使(shi)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)經(jing)(jing)濟性(xing)下(xia)降。因此蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)，一定要與(yu)(yu)(yu)發(fa)(fa)(fa)動(dong)(dong)機(ji)相匹配(pei)。通常蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)(he)(he)(he)容量(liang)(liang)的(de)(de)(de)(de)選(xuan)擇(ze)，應(ying)根據起動(dong)(dong)機(ji)功率(lv)、電(dian)(dian)(dian)(dian)壓和用電(dian)(dian)(dian)(dian)設備的(de)(de)(de)(de)負荷(he)(he)(he)(he)而定。

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(xing)物質脫(tuo)落，影響(xiang)其使(shi)用壽命(ming)。同時蓄電(dian)(dian)池(chi)并聯后并不(bu)能提供給起(qi)動(dong)(dong)機很大(da)的起(qi)動(dong)(dong)電(dian)(dian)流(liu)，更不(bu)利于(yu)發(fa)動(dong)(dong)機的起(qi)動(dong)(dong)。正確的方法應當是把存電(dian)(dian)不(bu)足的蓄電(dian)(dian)池(chi)拆下，換上充足電(dian)(dian)的蓄電(dian)(dian)池(chi)，然后再(zai)起(qi)動(dong)(dong)發(fa)動(dong)(dong)機。

鉛酸蓄電池串聯混用

在(zai)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)使用(yong)中，有(you)時會出現新(xin)(xin)、舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)串聯使用(yong)的(de)(de)現象，殊不知，這種做法會縮短蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)使用(yong)壽命(ming)。因(yin)為新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)內(nei)(nei)(nei)的(de)(de)化學(xue)反應物質較(jiao)多(duo)，端(duan)電(dian)(dian)(dian)(dian)壓較(jiao)高，內(nei)(nei)(nei)阻較(jiao)小(xiao)（12V新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)內(nei)(nei)(nei)阻只有(you)0.015-0.018Ω）；而舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)壓較(jiao)低，內(nei)(nei)(nei)阻較(jiao)大（12V舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)內(nei)(nei)(nei)阻在(zai)0.085Ω以(yi)上）。如果(guo)將新(xin)(xin)、舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)串聯混用(yong)，那么(me)在(zai)充(chong)電(dian)(dian)(dian)(dian)狀態下，舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)兩端(duan)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓將高于新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)兩端(duan)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓，結果(guo)造(zao)成新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)尚未充(chong)足而舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)早已過高；在(zai)放電(dian)(dian)(dian)(dian)狀態下，由(you)于新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)荷容量(liang)比舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)荷容量(liang)大，結果(guo)造(zao)成舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)過量(liang)放電(dian)(dian)(dian)(dian)，甚至造(zao)成舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)反極。因(yin)此對蓄(xu)(xu)(xu)(xu)(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)決(jue)不能新(xin)(xin)、舊(jiu)(jiu)(jiu)混用(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或放電，縮短其(qi)使用(yong)壽命(ming)。
