🔍 Key Concepts

• Lead-acid battery charging stages (bulk, absorption, float) • Effects of overcharging on temperature and gassing • What happens chemically as a battery approaches full charge

💭 Think About

• As a lead-acid battery gets closer to fully charged, what changes in how efficiently it can accept current? • Which choice directly addresses what could go wrong if you kept the initial high charging rate all the way to 100%? • Think about which options describe a problem to avoid versus a benefit to gain near the end of charging.

✅ Before You Answer

• Identify which option is focused on protecting the battery from damage near full charge • Ask: Which effect happens naturally as part of charging, and which must be limited or controlled? • Verify which process (gassing, overheating, lead peroxide formation, equalization, sulfate reduction) is most critical right before full charge.
