How long will the button cell battery in my torque screwdriver last?
扭矩螺丝刀的纽扣电池能使用多长时间？
The service life of a button cell battery is approximately two to three years. This is heavily dependent on the number of times it is used and the environmental conditions. The power consumption is much lower with a closed cap than when the cap is pulled back (adjustment mode).
钮扣电池的使用寿命约为二至三年。这在很大程度上取决于使用次数和环境条件。端帽关闭时的耗电量远低于端帽向后拉（调节模式）时的耗电量。
