合理使用充电电池是保障家用电器正常工作、延长充电电池寿命的关键。正确使用充电电池的方法是:首先要根据充电电池的容量确定充电时间。要测出充电器的充电电流,然后计算电池的合理充电时间,充电电池的充电安时数应为额定容量的1.4～1.5倍。例 The rational use of rechargeable batteries is to protect the normal operation of household appliances, rechargeable batteries to extend the life of the key. The correct method of using rechargeable batteries is: first of all, according to the capacity of rechargeable batteries to determine the charging time. To measure the charger’s charging current, and then calculate the battery’s reasonable charging time, charging the battery charging safety hours should be rated capacity of 1.4 to 1.5 times. example
