電瓶一直充電可能會造(zao)成損害，縮短其使用壽(shou)命。

正常(chang)情況下(xia)，電(dian)(dian)(dian)瓶4到5個小時就能充(chong)滿(man)。若是使用具備過(guo)(guo)充(chong)保(bao)(bao)護功能的充(chong)電(dian)(dian)(dian)器，充(chong)滿(man)后(hou)會(hui)(hui)自動斷電(dian)(dian)(dian)，不過(guo)(guo)即便如此，充(chong)滿(man)后(hou)也建議拔掉充(chong)電(dian)(dian)(dian)器。但(dan)普通充(chong)電(dian)(dian)(dian)器沒有過(guo)(guo)充(chong)保(bao)(bao)護功能，若一直充(chong)電(dian)(dian)(dian)，會(hui)(hui)對電(dian)(dian)(dian)瓶產(chan)生輕微(wei)損(sun)害。過(guo)(guo)充(chong)會(hui)(hui)讓電(dian)(dian)(dian)瓶極板硫化(hua)加劇(ju)，使得內阻增大，進而導致充(chong)放電(dian)(dian)(dian)性能變(bian)差(cha)，電(dian)(dian)(dian)量也會(hui)(hui)隨之減(jian)少，這不僅會(hui)(hui)影響(xiang)汽車啟動，還會(hui)(hui)影響(xiang)其運行。而且，過(guo)(guo)充(chong)產(chan)生的大量熱量會(hui)(hui)加速電(dian)(dian)(dian)瓶的老化(hua)。

汽車長(chang)時間停放時，電(dian)瓶電(dian)量會自然(ran)流失，過度放電(dian)同樣(yang)可(ke)能損壞電(dian)瓶。所以建議(yi)長(chang)期停放時，每隔一周啟動車輛(liang)5分鐘(zhong)以上給電(dian)瓶充(chong)(chong)電(dian)。總之，正確的充(chong)(chong)電(dian)方(fang)式很(hen)重要(yao)，充(chong)(chong)4到5小時為宜，避免(mian)過度充(chong)(chong)電(dian)，才能更好地延長(chang)電(dian)瓶使用(yong)壽命(ming)。
