人們在使用鉛酸蓄電池的過程中(zhong)常常會陷入(ru)誤區當中(zhong)，以下就介紹常見的幾種(zhong)使(shi)用(yong)誤區，給大家借鑒(jian)避免。

鉛酸蓄電池電荷容量與發動機不(bu)匹配

根據發動(dong)機(ji)類型和使用條(tiao)件(jian)合理選(xuan)用鉛酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)，是提(ti)高(gao)鉛酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池的(de)經濟(ji)性(xing)，延(yan)長其使用壽命的(de)重要(yao)(yao)途徑之(zhi)一。起(qi)動(dong)機(ji)起(qi)動(dong)發動(dong)機(ji)時(shi)，鉛酸(suan)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池輸出的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)很大(da)，在(zai)一般情況下(xia)為150A-200A，在(zai)低溫（-10℃）起(qi)動(dong)時(shi)輸出的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)高(gao)達250A-300A。如果(guo)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)與發動(dong)機(ji)不(bu)(bu)匹配，蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)偏小，則(ze)在(zai)起(qi)動(dong)阻力(li)大(da)時(shi)，小電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)的(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池在(zai)劇烈放電(dian)(dian)(dian)(dian)(dian)的(de)情況下(xia)，勢必(bi)加速單位(wei)時(shi)間(jian)內活(huo)性(xing)物(wu)質(zhi)與硫酸(suan)的(de)反應(ying)(ying)，使蓄(xu)電(dian)(dian)(dian)(dian)(dian)池溫度升高(gao)，極板(ban)因過負荷(he)而(er)彎曲，結果(guo)造成活(huo)性(xing)物(wu)質(zhi)大(da)量(liang)(liang)(liang)脫落(luo)，極板(ban)早期損壞，從而(er)使蓄(xu)電(dian)(dian)(dian)(dian)(dian)池壽命大(da)大(da)縮短。如果(guo)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)偏大(da)，雖然不(bu)(bu)會(hui)發生(sheng)上述問(wen)題，但不(bu)(bu)能充分(fen)利用其活(huo)性(xing)物(wu)質(zhi)，使蓄(xu)電(dian)(dian)(dian)(dian)(dian)池經濟(ji)性(xing)下(xia)降(jiang)。因此(ci)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)，一定要(yao)(yao)與發動(dong)機(ji)相匹配。通常蓄(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)容(rong)量(liang)(liang)(liang)的(de)選(xuan)擇，應(ying)(ying)根據起(qi)動(dong)機(ji)功率、電(dian)(dian)(dian)(dian)(dian)壓和用電(dian)(dian)(dian)(dian)(dian)設備的(de)負荷(he)而(er)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)(chong)電，極易造成極板活(huo)性(xing)物質脫落，影響(xiang)其使用(yong)壽命。同時蓄電池并聯后(hou)并不(bu)能提供給起動機(ji)很大的起動電流(liu)，更不(bu)利于(yu)發動機(ji)的起動。正確的方(fang)法應當是把存電不(bu)足(zu)(zu)的蓄電池拆下，換上(shang)充(chong)(chong)足(zu)(zu)電的蓄電池，然后(hou)再起動發動機(ji)。

鉛酸蓄電池串聯混用

在蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)使(shi)用(yong)中，有時會(hui)出(chu)現新(xin)(xin)、舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)串(chuan)聯使(shi)用(yong)的(de)(de)(de)現象，殊不知，這(zhe)種做(zuo)法會(hui)縮短(duan)蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)的(de)(de)(de)使(shi)用(yong)壽(shou)命。因為新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)內的(de)(de)(de)化學反(fan)應物(wu)質較(jiao)多，端(duan)電(dian)(dian)壓(ya)較(jiao)高，內阻較(jiao)小（12V新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)內阻只(zhi)有0.015-0.018Ω）；而(er)(er)舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)端(duan)電(dian)(dian)壓(ya)較(jiao)低，內阻較(jiao)大（12V舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)的(de)(de)(de)內阻在0.085Ω以上(shang)）。如果將新(xin)(xin)、舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)串(chuan)聯混(hun)用(yong)，那么在充電(dian)(dian)狀態(tai)(tai)下(xia)，舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)兩端(duan)的(de)(de)(de)充電(dian)(dian)電(dian)(dian)壓(ya)將高于(yu)新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)兩端(duan)的(de)(de)(de)充電(dian)(dian)電(dian)(dian)壓(ya)，結果造(zao)成新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)充電(dian)(dian)尚未充足(zu)而(er)(er)舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)充電(dian)(dian)早已過高；在放電(dian)(dian)狀態(tai)(tai)下(xia)，由(you)于(yu)新(xin)(xin)蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)荷容量(liang)比(bi)舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)荷容量(liang)大，結果造(zao)成舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)過量(liang)放電(dian)(dian)，甚至造(zao)成舊蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)反(fan)極(ji)。因此(ci)對蓄(xu)(xu)(xu)(xu)(xu)電(dian)(dian)池(chi)(chi)決不能新(xin)(xin)、舊混(hun)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(liang)充電(dian)或(huo)放電(dian)，縮(suo)短其使用壽命。
