New - Hydrovolt Battery Acid Tester

The Hydrovolt measures the specific gravity of wet cell battery electrolyte and determines the charge status of the battery/cell. This information is crucial to determine if acid was lost due to sulfation, acid/ water solution "boiling over" the cell or evaporation. 

• Handy & compact
• Large, easy-to-read scale
• Automatic air-lock prevents fluid loss and air bleed
