🔍 Key Concepts

• Basic battery maintenance practices on vessels • Purpose of electrolyte level and separator plates in storage batteries • Effects of overcharging and high charging rates on batteries

💭 Think About

• Which choice describes routine, ongoing care you would perform on almost any lead-acid storage battery? • Which options mention conditions that would actually damage the battery or reduce its life rather than preserve it? • Think about safety: which practice reduces fire, explosion, or corrosion hazards around the battery?

✅ Before You Answer

• Confirm which option keeps good electrical contact and reduces corrosion risk. • Check whether the electrolyte in a healthy battery should be above or below the separator plates. • Recall whether a continuous high charging rate is recommended or harmful for most storage batteries.
