危險，一般不(bu)建議這樣用，雖然(ran)沒有脈沖功(gong)能的(de)充(chong)(chong)電(dian)(dian)(dian)器(qi)，理論(lun)是可(ke)以給鋰電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)的(de)，但是依然(ran)可(ke)能會(hui)傷害鋰電(dian)(dian)(dian)池(chi)(chi)，雖然(ran)鋰電(dian)(dian)(dian)池(chi)(chi)有保護板，理論(lun)過(guo)(guo)充(chong)(chong)或者過(guo)(guo)放時候能起到保護作用，如果充(chong)(chong)電(dian)(dian)(dian)時經(jing)常觸發過(guo)(guo)充(chong)(chong)保護電(dian)(dian)(dian)壓(ya)(ya)，那這個充(chong)(chong)電(dian)(dian)(dian)器(qi)的(de)輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)設置就不(bu)正確。發生這樣的(de)現(xian)象(xiang)后，那落后的(de)電(dian)(dian)(dian)池(chi)(chi)永遠落后。有保護板也(ye)盡(jin)量不(bu)要(yao)高。因(yin)為電(dian)(dian)(dian)池(chi)(chi)在電(dian)(dian)(dian)池(chi)(chi)盒里(li)使用，平時是看不(bu)到電(dian)(dian)(dian)池(chi)(chi)的(de)一致(zhi)(zhi)性狀態(tai)的(de)，不(bu)知什么時候，萬一它的(de)一致(zhi)(zhi)性出(chu)問(wen)題了(le)，這時電(dian)(dian)(dian)壓(ya)(ya)又高了(le)幾V。那電(dian)(dian)(dian)池(chi)(chi)就要(yao)倒大霉了(le)。

實際上，鉛酸蓄電池充電器為(wei)了(le)克服鉛(qian)酸的(de)(de)(de)大(da)內阻,在恒(heng)(heng)流(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)把(ba)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)提高了(le)5%左右,也就是(shi)說(shuo)就是(shi)你選用了(le)一(yi)樣電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)充電(dian)(dian)(dian)(dian)(dian)(dian)器，給鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)候，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)會高出(chu)來一(yi)點的(de)(de)(de)，因(yin)為(wei)鉛(qian)酸的(de)(de)(de)內阻大(da)，恒(heng)(heng)流(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)為(wei)了(le)達到效率都是(shi)在恒(heng)(heng)流(liu)(liu)時(shi)把(ba)恒(heng)(heng)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)升高，這(zhe)樣對(dui)鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池是(shi)很不利的(de)(de)(de)。

主要(yao)是鉛(qian)酸電(dian)(dian)池充電(dian)(dian)過程(cheng)中有(you)二個電(dian)(dian)壓(ya)(ya)(ya)點(dian)會(hui)析氫(qing)和(he)析氧，析氧電(dian)(dian)壓(ya)(ya)(ya)點(dian)為13.8V，析氫(qing)電(dian)(dian)壓(ya)(ya)(ya)點(dian)為14.7V，所以鉛(qian)酸充電(dian)(dian)器的高(gao)恒壓(ya)(ya)(ya)定在(zai)14.7V*塊數；低恒壓(ya)(ya)(ya)（浮充電(dian)(dian)壓(ya)(ya)(ya)）定在(zai)13.8V*塊數。

鋰電(dian)(dian)池保(bao)(bao)(bao)護(hu)板(ban)的保(bao)(bao)(bao)護(hu)電(dian)(dian)壓(ya)點如果是4.2V,那放(fang)心使(shi)用(yong),無非就不要(yao)恒壓(ya)而已充電(dian)(dian),但普通的保(bao)(bao)(bao)護(hu)板(ban)啟動電(dian)(dian)壓(ya)時(shi)4.25V,加上+/-0.035V的誤差,不是很安(an)全吧? 18650可(ke)能(neng)沒多(duo)大事,鋁殼大單體(ti)難(nan)說了(le)，很多(duo)鋰電(dian)(dian)池使(shi)用(yong)的是正(zheng)常普通的保(bao)(bao)(bao)護(hu)板(ban),保(bao)(bao)(bao)護(hu)板(ban)截止保(bao)(bao)(bao)護(hu)電(dian)(dian)壓(ya)4.25V ，所以這(zhe)個保(bao)(bao)(bao)護(hu)在關鍵時(shi)候可(ke)能(neng)會起(qi)不到作用(yong)。

鋰(li)電(dian)池(chi)(chi)內阻小，比如13串鋰(li)電(dian)池(chi)(chi)也就是(shi)48伏(fu)，截止電(dian)壓要控制在54.6伏(fu)因為，而鉛酸(suan)電(dian)池(chi)(chi)恒流截止電(dian)壓是(shi)57.9伏(fu)，高出幾伏(fu)了(le)。

當然，鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)池如(ru)果(guo)改進一下(xia)是可(ke)以(yi)給(gei)鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的，比如(ru)去掉低(di)(di)恒壓階段(duan)電(dian)(dian)(dian)(dian)(dian)(dian)路和脈沖電(dian)(dian)(dian)(dian)(dian)(dian)路，是可(ke)以(yi)用的。如(ru)果(guo)你如(ru)果(guo)觀察鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)曲線，可(ke)以(yi)發現在恒流階段(duan)充(chong)(chong)(chong)入約為(wei)96%的總容(rong)(rong)量；恒壓減流階段(duan)只(zhi)充(chong)(chong)(chong)入4%的容(rong)(rong)量，如(ru)果(guo)轉燈就(jiu)(jiu)拔時，那鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)已經充(chong)(chong)(chong)入了99.5%的容(rong)(rong)量了。所以(yi)鉛酸充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器充(chong)(chong)(chong)鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)，也就(jiu)(jiu)是少了最后的均衡和浮充(chong)(chong)(chong)那0.5%的電(dian)(dian)(dian)(dian)(dian)(dian)量而已。將(jiang)鉛充(chong)(chong)(chong)的高低(di)(di)恒壓都低(di)(di)調點，就(jiu)(jiu)都可(ke)以(yi)給(gei)鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)了，只(zhi)不(bu)過(guo)(guo)充(chong)(chong)(chong)不(bu)滿(man)而已。不(bu)過(guo)(guo)鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)又不(bu)會硫化，充(chong)(chong)(chong)不(bu)滿(man)就(jiu)(jiu)充(chong)(chong)(chong)不(bu)滿(man)吧，又不(bu)影響使(shi)用，壽命還會延長呀。

還有一(yi)個方法，打開外殼，把三極(ji)管C極(ji)串聯那個電(dian)(dian)阻阻值提升10倍,恒流(liu)只(zhi)提升0.5%電(dian)(dian)壓,再(zai)調節下恒壓點,盡(jin)量做到(dao)(dao)每一(yi)個電(dian)(dian)池電(dian)(dian)壓均衡到(dao)(dao)4.18V左右為(wei)好。
