Precision battery hydrometer 1.100-1.300

Precision Battery Hydrometer 1.100–1.300 — Lead-Acid Battery State-of-Charge Tester

This syringe-style battery hydrometer draws electrolyte directly from the battery cell and reads specific gravity instantly via a built-in red/green float indicator — telling you exactly whether your lead-acid battery is fully charged, partially discharged, or needs replacement.

What Does the 1.100–1.300 Scale Mean?

The scale measures the specific gravity of battery electrolyte (sulfuric acid solution), which directly indicates charge level:

• 🟢 1.265–1.300 — Fully charged (green zone)
• 🟡 1.200–1.265 — Partially charged, recharge recommended
• 🔴 1.100–1.200 — Discharged or sulfated, battery may need replacement (red zone)

Compatible Battery Types

• ✅ Standard flooded / wet cell lead-acid batteries
• ✅ Car, motorcycle, forklift, and marine batteries
• ✅ Any vented lead-acid battery with removable cell caps
• ❌ Not compatible with sealed (VRLA), AGM, EFB, or lithium batteries — these cannot be sampled

Typical Use Cases

• Car & motorcycle owners: Check each cell individually to find a weak cell before the battery fails completely.
• Auto repair shops: Fast electrolyte sampling without removing the battery — result in under 30 seconds.
• Forklift & industrial battery maintenance: Monitor charge levels across large battery banks to schedule recharging efficiently.
• Seasonal vehicle storage: Verify battery charge before storing a vehicle for winter or extended periods.

How to Use

1. Remove the battery cell cap to access the electrolyte.
2. Insert the nozzle into the cell and squeeze then release the rubber bulb to draw electrolyte into the glass tube.
3. Hold the hydrometer level and read the float position against the graduated scale.
4. Compare to the red/green indicator: green float = charged, red float = discharged.
5. Return the electrolyte to the cell and replace the cap.

Note: Test after the battery has rested for at least 1 hour after charging or discharging for the most accurate reading. Electrolyte is corrosive — wear gloves and eye protection.
