人們在使用鉛酸蓄電池的過程中常(chang)常(chang)會陷入誤區當中，以下(xia)就介紹常(chang)見的幾種使用誤區，給大家借鑒避免。

鉛酸蓄電池電荷容量與(yu)發動(dong)機(ji)不匹配

根據發動(dong)(dong)(dong)機(ji)(ji)(ji)類型和(he)使(shi)用(yong)(yong)條件合理選(xuan)(xuan)用(yong)(yong)鉛酸(suan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)，是提(ti)高鉛酸(suan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池的經(jing)濟性(xing)(xing)，延長其使(shi)用(yong)(yong)壽命(ming)的重要途(tu)徑之(zhi)一(yi)。起(qi)(qi)動(dong)(dong)(dong)機(ji)(ji)(ji)起(qi)(qi)動(dong)(dong)(dong)發動(dong)(dong)(dong)機(ji)(ji)(ji)時(shi)(shi)，鉛酸(suan)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池輸出的電(dian)(dian)(dian)(dian)(dian)流很大(da)，在一(yi)般情(qing)況下(xia)為150A-200A，在低溫（-10℃）起(qi)(qi)動(dong)(dong)(dong)時(shi)(shi)輸出的電(dian)(dian)(dian)(dian)(dian)流高達250A-300A。如(ru)果蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)與發動(dong)(dong)(dong)機(ji)(ji)(ji)不匹(pi)配，蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)偏小(xiao)(xiao)，則在起(qi)(qi)動(dong)(dong)(dong)阻(zu)力大(da)時(shi)(shi)，小(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)的蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池在劇(ju)烈(lie)放電(dian)(dian)(dian)(dian)(dian)的情(qing)況下(xia)，勢必加速單位(wei)時(shi)(shi)間內活性(xing)(xing)物(wu)質與硫酸(suan)的反應，使(shi)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池溫度升高，極板(ban)因(yin)過負(fu)荷(he)(he)(he)而彎曲，結果造(zao)成活性(xing)(xing)物(wu)質大(da)量(liang)脫落，極板(ban)早(zao)期(qi)損(sun)壞，從(cong)而使(shi)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池壽命(ming)大(da)大(da)縮短。如(ru)果蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)偏大(da)，雖然不會發生上述問題，但(dan)不能充分利用(yong)(yong)其活性(xing)(xing)物(wu)質，使(shi)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池經(jing)濟性(xing)(xing)下(xia)降(jiang)。因(yin)此蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)，一(yi)定(ding)要與發動(dong)(dong)(dong)機(ji)(ji)(ji)相匹(pi)配。通(tong)常(chang)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)荷(he)(he)(he)容(rong)量(liang)的選(xuan)(xuan)擇，應根據起(qi)(qi)動(dong)(dong)(dong)機(ji)(ji)(ji)功(gong)率、電(dian)(dian)(dian)(dian)(dian)壓和(he)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)設備的負(fu)荷(he)(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(xing)物質脫(tuo)落，影響(xiang)其使用壽命。同時蓄電(dian)池并聯后并不能提供(gong)給起動(dong)機很大的(de)(de)(de)起動(dong)電(dian)流，更不利(li)于發動(dong)機的(de)(de)(de)起動(dong)。正確的(de)(de)(de)方法應當是把存電(dian)不足(zu)(zu)的(de)(de)(de)蓄電(dian)池拆(chai)下(xia)，換上(shang)充足(zu)(zu)電(dian)的(de)(de)(de)蓄電(dian)池，然后再(zai)起動(dong)發動(dong)機。

鉛酸蓄電池串聯混用

在(zai)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)使用(yong)中(zhong)，有(you)時會出現(xian)新(xin)(xin)、舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)串聯使用(yong)的(de)(de)現(xian)象，殊不(bu)知(zhi)，這(zhe)種做法會縮(suo)短蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)使用(yong)壽命(ming)。因(yin)為(wei)新(xin)(xin)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)的(de)(de)化學反(fan)應物(wu)質較(jiao)多，端(duan)(duan)電(dian)(dian)(dian)(dian)壓較(jiao)高(gao)，內(nei)阻較(jiao)小（12V新(xin)(xin)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)阻只(zhi)有(you)0.015-0.018Ω）；而舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)端(duan)(duan)電(dian)(dian)(dian)(dian)壓較(jiao)低，內(nei)阻較(jiao)大(da)（12V舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)內(nei)阻在(zai)0.085Ω以(yi)上(shang)）。如(ru)果將新(xin)(xin)、舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)串聯混用(yong)，那么(me)在(zai)充(chong)電(dian)(dian)(dian)(dian)狀態下(xia)，舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)兩端(duan)(duan)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓將高(gao)于(yu)新(xin)(xin)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)兩端(duan)(duan)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓，結(jie)果造(zao)成新(xin)(xin)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)尚未(wei)充(chong)足而舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)早已過高(gao)；在(zai)放(fang)電(dian)(dian)(dian)(dian)狀態下(xia)，由(you)于(yu)新(xin)(xin)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)荷容量比舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)荷容量大(da)，結(jie)果造(zao)成舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)過量放(fang)電(dian)(dian)(dian)(dian)，甚至造(zao)成舊蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)反(fan)極。因(yin)此對蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)決不(bu)能新(xin)(xin)、舊混用(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(chong)電或放電，縮(suo)短其使(shi)用壽(shou)命。
