新電瓶每次啟動(dong)都會掉一格電嗎(ma)？答案是(shi)不一定。

新電(dian)瓶(ping)啟動掉一格電(dian)，在某些情況(kuang)下(xia)是正常的。比如起步時力(li)矩大(da)，電(dian)流(liu)也大(da)，短時間大(da)功率(lv)輸出會讓(rang)瞬間電(dian)池壓降(jiang)嚴(yan)重，電(dian)量顯示盤電(dian)壓下(xia)降(jiang)，勻速行(xing)駛后可能就滿(man)格了。

要避免新電(dian)(dian)(dian)瓶啟動掉電(dian)(dian)(dian)，得注意(yi)正確使用充電(dian)(dian)(dian)器(qi)。充電(dian)(dian)(dian)器(qi)輸出電(dian)(dian)(dian)壓要和電(dian)(dian)(dian)瓶額定(ding)電(dian)(dian)(dian)壓相符。先(xian)插充電(dian)(dian)(dian)器(qi)與(yu)電(dian)(dian)(dian)池盒相連(lian)的插頭，再插交流(liu)電(dian)(dian)(dian)源插頭。充電(dian)(dian)(dian)時要注意(yi)防(fang)潮、防(fang)震動，放在通風散(san)熱的地方，嚴(yan)禁覆蓋(gai)。

鉛酸電(dian)池(chi)不是鋰電(dian)池(chi)，不能(neng)隨(sui)時(shi)(shi)充(chong)(chong)(chong)電(dian)，它的壽命(ming)按充(chong)(chong)(chong)放電(dian)次數算，最怕虧(kui)電(dian)，經(jing)常保持電(dian)量充(chong)(chong)(chong)足(zu)能(neng)延長壽命(ming)。充(chong)(chong)(chong)電(dian)時(shi)(shi)，充(chong)(chong)(chong)電(dian)器先紅燈后(hou)綠燈，變綠后(hou)要浮充(chong)(chong)(chong) 2 小時(shi)(shi)，能(neng)抑制(zhi)電(dian)池(chi)硫化。

長期深幅度(du)放電(dian)會讓電(dian)瓶(ping)極(ji)板(ban)軟(ruan)化，縮短使用壽命。還要防(fang)止長時間放電(dian)，電(dian)量降低 1/2 時就該充(chong)電(dian)。長期不用的電(dian)瓶(ping)，每月要充(chong)足電(dian)一次，一般充(chong)電(dian)器紅燈(deng)(deng)轉綠燈(deng)(deng)后繼(ji)續(xu)浮充(chong) 5 小時好。

如果新(xin)電(dian)瓶充滿(man)電(dian)后啟動掉(diao)一格(ge)且沒(mei)回(hui)升，要看看電(dian)池(chi)(chi)是(shi)不是(shi)全(quan)新(xin)的，是(shi)不是(shi)翻新(xin)電(dian)池(chi)(chi)，不是(shi)這(zhe)兩種情況可能是(shi)電(dian)池(chi)(chi)生(sheng)產質量有問(wen)題，得趕緊找商家更換(huan)。不是(shi)電(dian)池(chi)(chi)的問(wen)題，那就(jiu)可能是(shi)充電(dian)器故障導致(zhi)誤充。

想降(jiang)低新(xin)電瓶(ping)啟(qi)動掉一格(ge)電的(de)(de)概率，可以選擇合適的(de)(de)電瓶(ping)，定期檢(jian)查(cha)，避(bi)免(mian)過度放(fang)電，保持電瓶(ping)清潔。要是電瓶(ping)性能(neng)不(bu)足(zu)、容量小或者性能(neng)不(bu)好，可能(neng)滿足(zu)不(bu)了車輛啟(qi)動的(de)(de)電流需求。
