The percentage indicator indicates the point of freezing for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electrolyte solution batteries.

If the specific gravity measures between 1.100 and 1.220, the battery must be recharged. If the specific gravity is below 1.225 or a variation of .20 or greater specific gravity between battery cells indicates a need for battery equalization charging or indicates a weak cell. If the specific gravity is between 1.225 and 1.265, the battery is ok to test. If the hydrometer has a temperature correction chart, be sure to adjust the reading for the battery’s temperature. Variance of specific gravity between cells is not significant on discharged batteries (batteries with specific gravities below 1.225). However, if there is a variance of 50 points (0.050) in a battery whose specific gravity is 1225 or more, that battery is defective.
