Frequently Asked Questions
How do I use a battery hydrometer?
Insert the intake tube into the battery cell, squeeze the rubber bulb, and release it to draw electrolyte into the hydrometer. The float will rise to a level indicating the specific gravity. Compare the reading with the battery manufacturer's specifications to determine charge status.
What is the correct specific gravity reading for a fully charged battery?
A fully charged lead-acid battery typically shows a specific gravity between 1.265 and 1.285 at 25°C (77°F). However, always refer to the battery manufacturer's data for exact values. Readings lower than this may indicate a discharged or faulty cell.
Can I use this hydrometer on sealed or maintenance-free batteries?
No. This hydrometer is designed for serviceable lead-acid batteries with accessible liquid electrolyte. Sealed or gel-cell batteries require a conductance tester or other specialized equipment.
How should I clean and store the hydrometer?
After each use, rinse the hydrometer with fresh water and shake out excess liquid. Store it in a dry place away from direct sunlight and corrosive chemicals. Periodically inspect the rubber bulb and tube for cracks or deterioration and replace if necessary.
