人們在使用鉛酸蓄電池的過程中(zhong)常常會陷入誤區(qu)當(dang)中(zhong)，以下就(jiu)介紹(shao)常見的幾種(zhong)使用(yong)誤區(qu)，給(gei)大家借(jie)鑒避免。

鉛酸蓄電池電(dian)荷容量與(yu)發動(dong)機不匹配

根據發(fa)動(dong)機(ji)類型和(he)使(shi)(shi)用(yong)(yong)條(tiao)件合理(li)選(xuan)(xuan)用(yong)(yong)鉛(qian)酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)，是提(ti)高鉛(qian)酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)經(jing)濟(ji)性(xing)(xing)，延長(chang)其使(shi)(shi)用(yong)(yong)壽命的(de)重要(yao)途(tu)徑之(zhi)一。起動(dong)機(ji)起動(dong)發(fa)動(dong)機(ji)時，鉛(qian)酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)輸(shu)出的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流很大(da)，在(zai)一般(ban)情(qing)況(kuang)下(xia)為150A-200A，在(zai)低溫（-10℃）起動(dong)時輸(shu)出的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流高達(da)250A-300A。如(ru)果(guo)(guo)(guo)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)與(yu)發(fa)動(dong)機(ji)不匹配(pei)，蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)偏小，則在(zai)起動(dong)阻力(li)大(da)時，小電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)的(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)劇(ju)烈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)情(qing)況(kuang)下(xia)，勢必加速單位時間內活(huo)(huo)性(xing)(xing)物(wu)質(zhi)與(yu)硫酸(suan)的(de)反應，使(shi)(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)溫度(du)升高，極板因(yin)過(guo)負荷(he)(he)而彎曲，結果(guo)(guo)(guo)造成活(huo)(huo)性(xing)(xing)物(wu)質(zhi)大(da)量(liang)脫(tuo)落，極板早期損壞，從而使(shi)(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)壽命大(da)大(da)縮(suo)短。如(ru)果(guo)(guo)(guo)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)偏大(da)，雖然不會發(fa)生上(shang)述(shu)問(wen)題，但不能充分利用(yong)(yong)其活(huo)(huo)性(xing)(xing)物(wu)質(zhi)，使(shi)(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)經(jing)濟(ji)性(xing)(xing)下(xia)降(jiang)。因(yin)此蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)，一定(ding)要(yao)與(yu)發(fa)動(dong)機(ji)相(xiang)匹配(pei)。通常蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)容(rong)(rong)(rong)量(liang)的(de)選(xuan)(xuan)擇，應根據起動(dong)機(ji)功(gong)率、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備的(de)負荷(he)(he)而定(ding)。

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)，極易造成極板活性物質(zhi)脫落(luo)，影響其使用(yong)壽(shou)命(ming)。同時(shi)蓄(xu)電(dian)池(chi)并聯后(hou)并不能提供(gong)給(gei)起(qi)動(dong)機很大的(de)起(qi)動(dong)電(dian)流，更不利(li)于發(fa)動(dong)機的(de)起(qi)動(dong)。正確的(de)方法應當是(shi)把(ba)存電(dian)不足的(de)蓄(xu)電(dian)池(chi)拆(chai)下(xia)，換上充足電(dian)的(de)蓄(xu)電(dian)池(chi)，然后(hou)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)池(chi)(chi)(chi)(chi)(chi)(chi)使用(yong)中，有時(shi)會出現(xian)新(xin)(xin)、舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)串聯(lian)使用(yong)的(de)(de)現(xian)象，殊不知(zhi)，這種做法會縮短蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)使用(yong)壽命。因為新(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)化學反應物(wu)質較(jiao)(jiao)(jiao)多，端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)較(jiao)(jiao)(jiao)高，內(nei)阻(zu)較(jiao)(jiao)(jiao)小（12V新(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)內(nei)阻(zu)只有0.015-0.018Ω）；而(er)(er)舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)較(jiao)(jiao)(jiao)低，內(nei)阻(zu)較(jiao)(jiao)(jiao)大（12V舊(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(zai)0.085Ω以上）。如果(guo)將新(xin)(xin)、舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)串聯(lian)混用(yong)，那么在(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)狀態(tai)(tai)下，舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)兩(liang)端(duan)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)將高于新(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)兩(liang)端(duan)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，結果(guo)造成新(xin)(xin)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)尚未充(chong)(chong)(chong)足而(er)(er)舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)早(zao)已過高；在(zai)放電(dian)(dian)(dian)(dian)(dian)(dian)狀態(tai)(tai)下，由于新(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(liang)比舊(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(liang)大，結果(guo)造成舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)過量(liang)放電(dian)(dian)(dian)(dian)(dian)(dian)，甚至造成舊(jiu)(jiu)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(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)(chi)(chi)決不能新(xin)(xin)、舊(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(dian)或放電(dian)，縮短其使(shi)用(yong)壽命。
