A lithium-ion battery should never be:
- A left overnight at room temperature
- B short-circuited
- C recharged
- D left disconnected
Correct answer: B — short-circuited. From the official ISED question bank, verified word for word.
Why
A lithium-ion battery should never be short-circuited because connecting its positive and negative terminals directly with a wire causes a massive, uncontrolled surge of current. The full explanation — and one for every question — is in Pro.
