🔍 Key Concepts

• Edison-type storage cells use an alkaline electrolyte and are known for durability but still have limits • How temperature and overheating affect battery chemistry and capacity over time • Why electrolyte quality (purity, strength, age) matters to cell performance and capacity

💭 Think About

• Think about which listed conditions would cause permanent loss of capacity, not just temporary changes in performance • For each option, ask: would this likely damage plates, change electrolyte properties, or otherwise shorten the cell’s useful life? • Consider whether a lower-than-normal charge rate harms capacity, or whether other charging problems are usually more dangerous

✅ Before You Answer

• For choice involving temperature, recall what prolonged operation at high temperature does to internal components and electrolyte • For the choice about charging rate, distinguish between undercharging, overcharging, and normal slow charging effects on alkaline cells • For the choice about impure or weak electrolyte, consider what contamination or loss of strength does to chemical reactions inside the cell
