🔍 Key Concepts

• Lead-acid battery chemistry and what changes as it charges/discharges • Difference between voltage measurements and electrolyte measurements • How state of charge is typically checked in routine battery maintenance

💭 Think About

• When a lead-acid battery discharges, what physical or chemical property of the electrolyte changes in a measurable way? • Are voltage readings always stable and reliable, or can they be misleading under certain load or rest conditions? • Which option is something you can measure for each cell that directly reflects how much chemical energy remains?

✅ Before You Answer

• Which method is least affected by temporary load or surface charge conditions? • Which option reflects a direct change in electrolyte composition, not just electrical behavior? • Which option is most commonly used with a hydrometer during battery inspections?
