Why does 배터리가 없으면 mean if the tablet battery is dead / if there’s no charge, instead of if there is no battery physically inside it?

In everyday Korean, 배터리가 없다 often means the battery has run out or there’s no battery left, not necessarily that the battery is physically missing.

So in this sentence:

• 태블릿 배터리가 없으면 = if my tablet has no battery left / if the tablet is dead

Native speakers often use 없다 this way with batteries, money, time, etc., to mean not having any left.

More explicit alternatives would be:

• 배터리가 다 되면 = if the battery runs out
• 배터리가 방전되면 = if the battery is discharged

But 배터리가 없으면 is very natural in conversation.

Why is it 수업 전에 and not just 수업 전?

Both are possible, but they feel slightly different.

• 수업 전 = before class as a compact noun phrase
• 수업 전에 = before class / before the class starts with the time particle 에

In many everyday sentences, 전에 sounds more complete and natural when describing when something happens.

Compare:

• 수업 전 복습해요. = I review before class.
• 수업 전에 복습해요. = I review before class.

Both work, but 수업 전에 is very common in normal speech.

Also remember:

• 전 by itself is a noun meaning before
• 전에 is 전 + 에, used adverbially to mean before (something)
