人們在使用鉛酸蓄電池的過程中常常會(hui)陷入誤區當中，以下(xia)就介紹常見(jian)的幾種使用誤區，給大(da)家借鑒避免。

鉛酸蓄電池電荷容量與發動機不匹配

根據(ju)發(fa)動(dong)(dong)機(ji)類型和使(shi)用(yong)(yong)條件合理選用(yong)(yong)鉛(qian)酸蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)，是提高(gao)鉛(qian)酸蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)經(jing)濟性，延長其使(shi)用(yong)(yong)壽命的(de)(de)重要(yao)途徑之(zhi)一。起動(dong)(dong)機(ji)起動(dong)(dong)發(fa)動(dong)(dong)機(ji)時(shi)，鉛(qian)酸蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)輸出(chu)的(de)(de)電(dian)(dian)(dian)(dian)流很大(da)(da)，在(zai)(zai)一般情況(kuang)下為150A-200A，在(zai)(zai)低溫(wen)（-10℃）起動(dong)(dong)時(shi)輸出(chu)的(de)(de)電(dian)(dian)(dian)(dian)流高(gao)達250A-300A。如果(guo)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)與(yu)(yu)發(fa)動(dong)(dong)機(ji)不(bu)匹配，蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)偏小(xiao)，則在(zai)(zai)起動(dong)(dong)阻力大(da)(da)時(shi)，小(xiao)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)的(de)(de)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在(zai)(zai)劇烈放電(dian)(dian)(dian)(dian)的(de)(de)情況(kuang)下，勢必加速單位時(shi)間內活性物(wu)質(zhi)與(yu)(yu)硫酸的(de)(de)反應(ying)，使(shi)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)溫(wen)度(du)升高(gao)，極板因過負(fu)荷(he)而彎曲，結果(guo)造成活性物(wu)質(zhi)大(da)(da)量(liang)(liang)脫落，極板早期損(sun)壞，從而使(shi)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)壽命大(da)(da)大(da)(da)縮短。如果(guo)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)偏大(da)(da)，雖然不(bu)會發(fa)生上述問題(ti)，但不(bu)能(neng)充(chong)分利用(yong)(yong)其活性物(wu)質(zhi)，使(shi)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)經(jing)濟性下降。因此蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)，一定要(yao)與(yu)(yu)發(fa)動(dong)(dong)機(ji)相匹配。通常蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)荷(he)容(rong)(rong)量(liang)(liang)的(de)(de)選擇，應(ying)根據(ju)起動(dong)(dong)機(ji)功率、電(dian)(dian)(dian)(dian)壓和用(yong)(yong)電(dian)(dian)(dian)(dian)設備的(de)(de)負(fu)荷(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(chong)電，極(ji)易造成極(ji)板活性物質脫落，影響其使用壽命(ming)。同時蓄電池(chi)并(bing)(bing)聯后(hou)并(bing)(bing)不能(neng)提供給起(qi)動(dong)(dong)(dong)機很(hen)大的(de)起(qi)動(dong)(dong)(dong)電流(liu)，更不利于發(fa)動(dong)(dong)(dong)機的(de)起(qi)動(dong)(dong)(dong)。正確(que)的(de)方法應(ying)當是把存電不足的(de)蓄電池(chi)拆下，換上充(chong)足電的(de)蓄電池(chi)，然后(hou)再(zai)起(qi)動(dong)(dong)(dong)發(fa)動(dong)(dong)(dong)機。

鉛酸蓄電池串聯混用

在蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)使(shi)用中，有時會(hui)出(chu)現(xian)新(xin)(xin)(xin)、舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)串聯使(shi)用的(de)(de)現(xian)象，殊不(bu)知(zhi)，這種做法會(hui)縮短蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)使(shi)用壽命。因(yin)為新(xin)(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)內(nei)的(de)(de)化學(xue)反應物質較(jiao)多，端(duan)(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)較(jiao)高，內(nei)阻(zu)較(jiao)小（12V新(xin)(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)內(nei)阻(zu)只(zhi)有0.015-0.018Ω）；而舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)端(duan)(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)較(jiao)低，內(nei)阻(zu)較(jiao)大(da)（12V舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)內(nei)阻(zu)在0.085Ω以上(shang)）。如果(guo)(guo)(guo)將新(xin)(xin)(xin)、舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)串聯混(hun)用，那么在充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)下(xia)，舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)兩(liang)端(duan)(duan)(duan)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)將高于新(xin)(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)兩(liang)端(duan)(duan)(duan)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，結果(guo)(guo)(guo)造(zao)成(cheng)(cheng)新(xin)(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)尚未(wei)充(chong)足(zu)而舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)早(zao)已(yi)過(guo)高；在放電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)下(xia)，由(you)于新(xin)(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷容量比舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷容量大(da)，結果(guo)(guo)(guo)造(zao)成(cheng)(cheng)舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)過(guo)量放電(dian)(dian)(dian)(dian)(dian)(dian)，甚至造(zao)成(cheng)(cheng)舊(jiu)(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)反極。因(yin)此對(dui)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)決不(bu)能新(xin)(xin)(xin)、舊(jiu)(jiu)(jiu)混(hun)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量充電或放(fang)電，縮短(duan)其使(shi)用壽命。
