危險，一般不(bu)(bu)建議這(zhe)樣(yang)用，雖然(ran)沒有脈沖功能(neng)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，理論是(shi)可以給鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)，但是(shi)依然(ran)可能(neng)會傷害鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，雖然(ran)鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)有保護(hu)板(ban)，理論過(guo)充(chong)或者過(guo)放(fang)時(shi)候能(neng)起到保護(hu)作用，如(ru)果充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)經常觸發過(guo)充(chong)保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，那(nei)(nei)這(zhe)個充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓設置就不(bu)(bu)正確。發生這(zhe)樣(yang)的(de)(de)現象后(hou)，那(nei)(nei)落(luo)后(hou)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)永遠(yuan)落(luo)后(hou)。有保護(hu)板(ban)也(ye)盡量不(bu)(bu)要(yao)高(gao)。因為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)盒里使用，平時(shi)是(shi)看(kan)不(bu)(bu)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)一致性(xing)狀態的(de)(de)，不(bu)(bu)知什么時(shi)候，萬(wan)一它的(de)(de)一致性(xing)出問題了，這(zhe)時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓又高(gao)了幾V。那(nei)(nei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)就要(yao)倒大霉了。

實際上，鉛酸蓄電池充電器為了(le)克服鉛(qian)酸(suan)(suan)的大內阻,在(zai)恒流充(chong)電(dian)(dian)(dian)時把(ba)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)提(ti)高了(le)5%左(zuo)右,也就是(shi)說就是(shi)你選用了(le)一樣電(dian)(dian)(dian)壓(ya)(ya)充(chong)電(dian)(dian)(dian)器，給鋰電(dian)(dian)(dian)池(chi)供電(dian)(dian)(dian)時候(hou)，電(dian)(dian)(dian)壓(ya)(ya)會高出(chu)來(lai)一點的，因為鉛(qian)酸(suan)(suan)的內阻大，恒流充(chong)電(dian)(dian)(dian)為了(le)達到(dao)效率都是(shi)在(zai)恒流時把(ba)恒壓(ya)(ya)電(dian)(dian)(dian)壓(ya)(ya)升(sheng)高，這樣對鋰電(dian)(dian)(dian)池(chi)是(shi)很(hen)不(bu)利(li)的。

主要(yao)是鉛酸電(dian)(dian)池充電(dian)(dian)過程中有二個(ge)電(dian)(dian)壓點(dian)(dian)會析氫和析氧，析氧電(dian)(dian)壓點(dian)(dian)為(wei)13.8V，析氫電(dian)(dian)壓點(dian)(dian)為(wei)14.7V，所(suo)以鉛酸充電(dian)(dian)器的高恒壓定(ding)在14.7V*塊數(shu)；低(di)恒壓（浮(fu)充電(dian)(dian)壓）定(ding)在13.8V*塊數(shu)。

鋰電(dian)池保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)板(ban)的保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)電(dian)壓(ya)(ya)點如果是(shi)4.2V,那放(fang)心使用,無非就不要恒壓(ya)(ya)而已充電(dian),但(dan)普通的保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)板(ban)啟動電(dian)壓(ya)(ya)時4.25V,加上+/-0.035V的誤差,不是(shi)很安全(quan)吧(ba)? 18650可(ke)能(neng)沒多大事,鋁殼大單體難說了，很多鋰電(dian)池使用的是(shi)正常普通的保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)板(ban),保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)板(ban)截(jie)止(zhi)保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)電(dian)壓(ya)(ya)4.25V ，所以這個保(bao)(bao)(bao)(bao)(bao)護(hu)(hu)(hu)在關(guan)鍵(jian)時候(hou)可(ke)能(neng)會起不到作(zuo)用。

鋰電(dian)池(chi)內阻小，比如13串鋰電(dian)池(chi)也就是48伏(fu)，截止電(dian)壓(ya)要控制在54.6伏(fu)因(yin)為(wei)，而鉛酸電(dian)池(chi)恒流截止電(dian)壓(ya)是57.9伏(fu)，高出(chu)幾伏(fu)了。

當然，鉛酸(suan)電(dian)(dian)(dian)池(chi)如果(guo)改進(jin)一下是可以(yi)給鋰(li)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)的(de)，比(bi)如去(qu)掉低恒壓階(jie)(jie)(jie)段電(dian)(dian)(dian)路和脈沖電(dian)(dian)(dian)路，是可以(yi)用的(de)。如果(guo)你如果(guo)觀察鋰(li)電(dian)(dian)(dian)的(de)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)曲線，可以(yi)發(fa)現在恒流階(jie)(jie)(jie)段充(chong)(chong)(chong)(chong)(chong)(chong)入(ru)約為96%的(de)總容量；恒壓減流階(jie)(jie)(jie)段只(zhi)充(chong)(chong)(chong)(chong)(chong)(chong)入(ru)4%的(de)容量，如果(guo)轉燈就拔(ba)時，那(nei)鋰(li)電(dian)(dian)(dian)已經充(chong)(chong)(chong)(chong)(chong)(chong)入(ru)了99.5%的(de)容量了。所以(yi)鉛酸(suan)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器充(chong)(chong)(chong)(chong)(chong)(chong)鋰(li)電(dian)(dian)(dian)，也就是少了最后的(de)均衡和浮(fu)充(chong)(chong)(chong)(chong)(chong)(chong)那(nei)0.5%的(de)電(dian)(dian)(dian)量而已。將(jiang)鉛充(chong)(chong)(chong)(chong)(chong)(chong)的(de)高(gao)低恒壓都低調點，就都可以(yi)給鋰(li)電(dian)(dian)(dian)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)了，只(zhi)不(bu)過充(chong)(chong)(chong)(chong)(chong)(chong)不(bu)滿(man)(man)而已。不(bu)過鋰(li)電(dian)(dian)(dian)又(you)不(bu)會硫化，充(chong)(chong)(chong)(chong)(chong)(chong)不(bu)滿(man)(man)就充(chong)(chong)(chong)(chong)(chong)(chong)不(bu)滿(man)(man)吧，又(you)不(bu)影響使用，壽命(ming)還會延長(chang)呀。

還(huan)有一(yi)個(ge)方法，打開外殼，把(ba)三極管C極串聯(lian)那(nei)個(ge)電(dian)阻阻值提升10倍,恒流只提升0.5%電(dian)壓,再調節下恒壓點,盡量做到每一(yi)個(ge)電(dian)池電(dian)壓均衡到4.18V左右(you)為好。
