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(ti)供(gong)的(de)最高(gao)電(dian)(dian)(dian)壓應有限制，6V電(dian)(dian)(dian)池的(de)充電(dian)(dian)(dian)電(dian)(dian)(dian)壓為(wei)(wei)7.2―7.5V，12V電(dian)(dian)(dian)池充電(dian)(dian)(dian)電(dian)(dian)(dian)壓為(wei)(wei)14.4―15V，充電(dian)(dian)(dian)最大(da)電(dian)(dian)(dian)流(liu)(liu)不大(da)于額定容(rong)量值的(de)30%A（比如2A．H的(de)蓄電(dian)(dian)(dian)池最大(da)充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)不能大(da)于2×0.3=0.6安培）；以10小時充電(dian)(dian)(dian)率為(wei)(wei)宜（比如2A．H的(de)蓄電(dian)(dian)(dian)池以0.2安培為(wei)(wei)宜），若充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)過大(da)，則蓄電(dian)(dian)(dian)池易發熱，造成極板脫落(luo)、斷裂(lie)、短路以致造成爆炸、燃(ran)燒等(deng)事故。
