What is the effect of low temperature on the operation of a lead-acid storage battery?

🔍 Key Concepts

• Effect of temperature on chemical reactions in a lead-acid battery • Relationship between specific gravity (sg) of electrolyte and freezing point • How battery capacity (available amp-hours) changes in cold conditions

💭 Think About

• Think about what happens to most chemical reactions when temperature drops — do they speed up or slow down, and how would that affect a battery’s capacity? • How does a lower specific gravity (weaker acid solution) affect the freezing point of the electrolyte inside the battery case? • Could more than one of the listed effects realistically happen to a lead-acid battery at low temperatures?

✅ Before You Answer

• Confirm whether cold temperatures reduce the effective capacity (usable energy) of a lead-acid battery. • Check if electrolyte with low specific gravity is more likely to freeze and damage the battery case or plates. • Ask yourself if both listed effects can occur together, and whether any choice reflects that combination.

What is the effect of low temperature on the operation of a lead-acid storage battery?

Electrolyte may freeze and split the battery if sg too low

The capacity is decreased

A & B

None of the above
