🔍 Key Concepts

• Lead-acid battery capacity testing and why a full discharge is sometimes used • Difference between capacity, state of charge, and specific gravity • What battery plate composition means and how (or if) it is checked in service

💭 Think About

• Which of the choices would reasonably require completely discharging a battery under controlled conditions? • Which items can be checked quickly with simple instruments (like a hydrometer or voltmeter) without a long discharge test? • In normal shipboard maintenance, when would engineers schedule a long, timed discharge on a battery bank?

✅ Before You Answer

• Identify which option refers to a measurement that is time‑based under a known load. • Eliminate any options that are normally checked with a hydrometer reading or voltage test, not a long discharge. • Ask yourself which test is usually done infrequently and under supervision, often after installation or periodically in service.
