Q

With a fully automatic GMDSS compliant battery charger / power supply, when must the high charging process be interrupted?

🔍 Key Concepts

• GMDSS battery charger behavior during normal operation and high-rate (boost) charging • What happens inside a lead-acid battery at high charge rates (temperature, gas production, electrolyte boiling) • Purpose of an automatic, voltage-sensing charger in preventing battery damage and safety hazards

💭 Think About

• When a GMDSS charger is in "high charge" or "boost" mode, what physical or chemical change inside the battery becomes the primary safety concern? • Of the choices given, which one relates directly to a gas hazard that an automatic system would be designed to prevent before it becomes dangerous? • Think about which condition, if allowed to continue, could create an explosion risk in a confined battery compartment.

✅ Before You Answer

• Identify which option refers specifically to gas generation rather than just temperature comfort or general overheating. • Recall that lead-acid batteries produce hydrogen and oxygen gas when overcharged—verify what the charger is trying to avoid. • Confirm that an automatic GMDSS charger is designed to switch from high charge to float mode when a certain battery voltage / charge state is reached, to prevent excessive gas production.
