饱和标准电池有优越的长期稳定度,在现代标准实验室中都用一组饱和标准电池来维持其电压标准。标准电池的稳定度将受到机械震动和温度骤变或改变的影响。受机械震动而使电压变化是短暂的,几分钟或儿小时即能恢复,但因温度骤变而引起的电压变化却需较长时间才能稳定,有的甚至需要几个星期,这是由于电池固 Saturated standard batteries have excellent long-term stability, in a modern standard laboratory with a standard set of saturated batteries to maintain their voltage standards. The stability of a standard battery will be affected by mechanical shock and sudden changes in temperature or changes. By mechanical vibration and voltage changes are brief, a few minutes or hours can be restored, but due to sudden changes in temperature caused by the voltage change takes a long time to stabilize, and some even take a few weeks, it is because the battery solid
