Which of the following statements are true when safely handling of batteries and portable computer case assemblies with built-in battery? (Choose three.)

Question

Options

• ALift batteries or case assemblies using the battery cable.
• BIf a battery is dropped, it can be reused after visual inspection.
• CTechnicians should put on nitrile or lint free gloves when dealing with hot batteries.
• DIf something unusual is noticed (such as an odor, swelling, discoloration, deformity or overheating),
• ENever attempt to separate or remove the battery from a case assembly that has a built-in battery.
• FDo not expose lithium batteries to high temperatures.
• GWhen performing a visual inspection, view the battery from about one foot away.

• A
  4% (1)
• B
  92% (22)
• D
  4% (1)

Explanation

Looking at the given answer key (B, C, G), I want to be transparent: this answer key appears to have errors, and explaining it as written would be misleading for exam preparation.

Here's why B and G are actually the wrong choices, while E and F are almost certainly correct:

• B is false: A dropped battery should generally not be reused even after visual inspection - internal damage (like separator tears in lithium cells) is invisible externally. The safe answer is disposal.
• G is false: Inspecting from one foot away defeats the purpose of a visual inspection. Close-up inspection under good lighting is standard practice.
• E is true: Never attempting to separate a built-in battery is correct safety guidance - it risks puncture, short circuit, and thermal runaway.
• F is true: Avoiding high temperatures for lithium batteries is a fundamental safety rule (heat causes pressure buildup and fire risk).

The three most defensible correct answers are C, E, and F:

• C: Nitrile or lint-free gloves protect against chemical exposure from hot/compromised batteries.
• E: Built-in battery assemblies must not be forcibly separated - correct handling means replacing the whole assembly.
• F: Lithium batteries must never be stored or used near heat sources.

Memory tip: Think "Protect, Preserve, Prevent" - gloves protect you (C), intact assemblies preserve safety (E), and avoiding heat prevents thermal events (F).

I'd recommend cross-referencing this question against your study guide or official source, as the listed answer key (B, C, G) conflicts with standard battery safety practices.
