便携式无线通信设备使用的电池都具有恢复效应，在非连续放电模式下放电时，电池的能量转换效率明显提高，所以合理设计电池的放电模式对于低功耗无线通信设计具有积极的意义。电池的恢复效应涉及复杂的物理化学反应，不易建立简单实用的数学模型，通过电池放电实验，给出电池在不同放电占空比条件下的性能曲线。实验结果表明，随放电占空比的减小，电池能量转换效率不断提高，但存在放电占空比门限。

The batteries used in portable wireless communication devices were with recovery effect. When discharge in the non-continuous mode, the energy conversion efficiency of battery was improved significantly. Therefore, the rational design of battery discharge mode had a positive gain for low power wireless communication design. Complex physical and chemical reaction were involved in recovery effect of battery. It was difficult to establish a simple and practical mathematical model. The experiments for the battery performance with different discharge duty cycle was performed. The experimental results show that the battery conversion efficiency gets higher when discharge duty cycle gets smal er, but there is a threshold of discharge duty cycle.
