Quick & Accurate Battery Health Testing Tool

The Metro Battery Hydrometer 82520 is a simple yet essential diagnostic tool used to check the state of charge of lead-acid batteries by measuring the electrolyte’s specific gravity.

It works by drawing battery fluid into the tube and reading the float level, which indicates whether the battery is fully charged, low, or discharged.

🔧 Key Features:

✔️ Fast & Accurate Testing – Instantly checks battery condition
✔️ Easy to Use Design – Simple suction bulb operation
✔️ Color-Coded Indicator – Quick reading (Green / White / Red)
✔️ Durable Construction – Suitable for workshop and garage use
✔️ Factory Calibrated – Ready for accurate measurement
✔️ Portable & Lightweight – Easy to carry

⚙️ How It Works:

Insert the nozzle into the battery cell
Squeeze and release the bulb to draw electrolyte
Read the floating indicator scale

Green → Fully charged
White → Low charge
Red → Discharged

⚙️ Applications:

Car battery testing
Bike & inverter battery maintenance
Workshop diagnostics
Industrial battery servicing
