🔍 Key Concepts

• Hydrometer temperature correction for lead-acid batteries • How specific gravity changes with temperature (denser/less dense) • Standard reference temperature (around 80°F for most battery charts)

💭 Think About

• When a battery is warmer than 80°F, would the electrolyte be more or less dense, and would the hydrometer reading be artificially high or low? • If the hydrometer reading is affected by temperature, do you need to add or subtract points to bring it back to what it would be at 80°F? • Look at the size of the correction: is it more common to correct by about 10 points per small temperature change, or a smaller number of points per larger change?

✅ Before You Answer

• Confirm whether higher temperature makes the apparent specific gravity increase or decrease. • Identify whether the correction factor is expressed per 4°F or per 10°F, and how that compares with standard marine battery practice. • Make sure the direction (add vs subtract) would move the observed reading toward what it would be at the standard 80°F reference.

What should be done when correcting specific gravity readings of a lead-acid battery for existing temperature conditions?

add 10 correction points for each 4°F the battery temperature is above 80°F

subtract 10 correction points for each 4°F the battery temperature is above 80°F

add 4 correction points for each 10°F the battery temperature is above 80°F

subtract 4 correction points for each 10°F the battery temperature is above 80°F
