Embodiments of the invention disclose a charging-discharging method and apparatus for a standby battery of a vehicle-mounted terminal. The charging method for the standby battery of the vehicle-mounted terminal comprises the steps that when the voltage of the standby battery of the vehicle-mounted terminal reaches a charging threshold value, the standby battery is initially charged by a first current; the charging voltage of the standby battery in the charging process is monitored; when the charging voltage is boosted to the voltage threshold value for switching the charging current, the standby battery is continuously charged by a second current, wherein the second current numerical value is less than the first current numerical value. By adoption of the charging method, the condition of over-charge or over-discharge of the standby battery can be avoided, so that the service life of the standby battery is prolonged. 本发明实施例公开了种车载终端备用电池充放电方法及装置。其中，车载终端备用电池充电方法包括：当车载终端备用电池电压达到充电阈值时，以第电流对备用电池进行初始充电；监控充电过程中备用电池的充
