🔍 Key Concepts

• Behavior of a lead-acid battery during normal charging vs overcharging • What causes gassing (bubbling) in the electrolyte of a lead-acid battery • The relationship between charging rate, temperature, and gas production

💭 Think About

• Think about what physically creates gas bubbles inside a lead-acid battery when current is applied. • Ask yourself: which option directly relates to the amount of current being pushed into the battery, rather than a condition of the compartment or the electrolyte? • Consider what would most likely happen if you continued charging in this condition—what component or setting would you want to adjust first?

✅ Before You Answer

• Identify which choice refers to a problem with the charging process itself, not the battery construction or compartment. • Recall that some gassing is normal at the end of charge, but violent gassing usually indicates an abnormal condition. • Verify which option would most likely cause overheating and excessive electrolysis of water in the electrolyte.
