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)(de)最高電(dian)(dian)(dian)壓應(ying)有限制，6V電(dian)(dian)(dian)池的(de)(de)(de)充電(dian)(dian)(dian)電(dian)(dian)(dian)壓為(wei)7.2―7.5V，12V電(dian)(dian)(dian)池充電(dian)(dian)(dian)電(dian)(dian)(dian)壓為(wei)14.4―15V，充電(dian)(dian)(dian)最大電(dian)(dian)(dian)流(liu)不大于額定容(rong)量值的(de)(de)(de)30%A（比如2A．H的(de)(de)(de)蓄電(dian)(dian)(dian)池最大充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)不能大于2×0.3=0.6安(an)培）；以10小時充電(dian)(dian)(dian)率為(wei)宜（比如2A．H的(de)(de)(de)蓄電(dian)(dian)(dian)池以0.2安(an)培為(wei)宜），若充電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)過大，則(ze)蓄電(dian)(dian)(dian)池易發熱(re)，造成極(ji)板脫落、斷(duan)裂、短路以致造成爆炸、燃(ran)燒等事故。
