・if I have spare power
・if I have reserve strength

「如果有餘力的話」在英語中可以用 if I have spare power 或 if I have reserve strength 等來表達。

I'm pretty busy today, so if I have spare power, I'll do it.
（我今天很忙，所以如果有餘力的話，我會做的。）

If I have reserve strength, I would like to deal with it, but honestly, I have to say that it is difficult in the current situation.
（如果有餘力的話，我想處理它，但老實說，在目前的情況下很難。）
