一個100AH的蓄電池，充電電流最大不能大于30A。循環充電時，充電器提供的(de)(de)最(zui)高電(dian)(dian)(dian)壓(ya)應有(you)限(xian)制，6V電(dian)(dian)(dian)池(chi)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)為7.2―7.5V，12V電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)為14.4―15V，充(chong)(chong)(chong)電(dian)(dian)(dian)最(zui)大(da)電(dian)(dian)(dian)流不(bu)大(da)于額定容量值的(de)(de)30%A（比如(ru)2A．H的(de)(de)蓄(xu)電(dian)(dian)(dian)池(chi)最(zui)大(da)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流不(bu)能大(da)于2×0.3=0.6安培）；以(yi)10小(xiao)時充(chong)(chong)(chong)電(dian)(dian)(dian)率為宜（比如(ru)2A．H的(de)(de)蓄(xu)電(dian)(dian)(dian)池(chi)以(yi)0.2安培為宜），若(ruo)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流過大(da)，則蓄(xu)電(dian)(dian)(dian)池(chi)易發(fa)熱，造(zao)成(cheng)(cheng)極板脫落、斷裂(lie)、短路以(yi)致(zhi)造(zao)成(cheng)(cheng)爆炸、燃(ran)燒(shao)等(deng)事故。
