🔍 Key Concepts

• Lead-acid battery charging stages (bulk, absorption, float) • What gassing indicates about battery voltage and state of charge • Effects of overcharging on electrolyte level and plate condition

💭 Think About

• When a battery starts gassing freely under a normal charge, what does that suggest about how close it is to full charge? • How does continuous heavy gassing affect the battery’s plates and electrolyte over time? • Which action best protects battery life while still allowing proper charging?

✅ Before You Answer

• Confirm what "gassing freely" usually means in terms of reaching or exceeding gassing voltage • Consider which choice might lead to overheating or excessive water loss • Eliminate any option that would clearly increase stress on the battery once gassing has started
