🔍 Key Concepts

• Effects of low temperature on lead-acid battery capacity • How electrolyte freezing point changes with state of charge (specific gravity) • Manufacturer and safety guidance for charging/discharging batteries in cold conditions

💭 Think About

• Think about what happens to a lead-acid battery’s available capacity when it gets very cold. Does it increase, decrease, or stay the same? • How does keeping the battery well charged affect the temperature at which the electrolyte will freeze? • Which answer choice best matches both the performance effect and the safety/freezing concern at low temperatures?

✅ Before You Answer

• Verify how low temperature affects battery capacity (ampere-hours) for lead-acid cells • Check whether a fully charged vs discharged battery is more likely to freeze • Confirm whether the correct option must address only one effect or both major effects of low temperature
