1、48V新電(dian)池要求充電(dian)器參數(shu)，最高(gao)電(dian)壓(ya)58.5---59.7，不(bu)低于58V，低于58V造(zao)(zao)成充電(dian)不(bu)足(zu)，高(gao)于59.7V可能造(zao)(zao)成充電(dian)不(bu)轉燈。轉燈電(dian)流約(yue)0.4---0.7A，實(shi)際電(dian)壓(ya)約(yue)55.5V，低于50V造(zao)(zao)成充電(dian)不(bu)足(zu)，長時間充電(dian)電(dian)池虧電(dian)。

2、4820電池要求充電最大電流2.4----3.3A，低(di)于2.2A充電慢(man)，充電效果差。

3、市場上低于30元的(de)充電器實(shi)際功率(lv)小(xiao)，參數設計不(bu)精確，請(qing)注意區分。

4、充電器穩(wen)壓(ya)(ya)電路失效會造(zao)成輸出電壓(ya)(ya)75---130V，充電電池滾燙不轉燈。

5、當新電(dian)池出現，續航里(li)程20A電(dian)池低于30公(gong)里(li)，12A電(dian)池低于25公(gong)里(li)請檢查(cha)充(chong)電(dian)器各項參數，如(ru)果(guo)無法判斷是，請更換優(you)質充(chong)電(dian)器再次使用，即可解(jie)決問題(ti)。

6、新(xin)電(dian)池(chi)遇到不轉燈時(shi)，請更(geng)換另外(wai)一個優(you)質(zhi)充電(dian)器試機。

7、正常(chang)情況下(xia)。4820新電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)(jian)(jian)約10小(xiao)時(shi)左右，續航(hang)里程(cheng)40---60公里，4812新電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)(jian)(jian)約10小(xiao)時(shi)內，里程(cheng)達到(dao)25---40公里，如果正常(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)(jian)(jian)超過以上，請更(geng)換優(you)質充(chong)(chong)(chong)電(dian)(dian)(dian)器再次使用(yong)。

8、有很(hen)多充電(dian)(dian)器(qi)內部電(dian)(dian)路、輸入輸出連線(xian)老化(hua)，造(zao)成，有時候能(neng)充、有時候不能(neng)沖。嚴重影響電(dian)(dian)池，或者充電(dian)(dian)過(guo)程中(zhong)電(dian)(dian)路失效，造(zao)成充鼓包(bao)，如(ru)果出現這種(zhong)情況，請直接(jie)更換優質充電(dian)(dian)器(qi)再次使用。
