時鐘入鹼性電池和碳性電池的分別？

Both types of batteries 鹼性電池和碳性電池 can work. No problem and no different.

But, I suggest you do NOT use alkaline battery 鹼性電池.
Because,
1. It is not economic to use alkaline battery in electronic clock.
2. Alkaline battery can drive you clock to run very long time without replacement, but as time goes on, the alkaline battery is very easy to leak and damage your clock.

時鐘入鹼性電池和碳性電池的分別在於耐用 時鐘本身有限流 穩壓功能 不存在 勁得濟 之慮

其實時鐘是不能入鹼性電池，因為時鐘是行石英的，而鹼性電池與石英是相“黑”的
