## Long description

Hazet 4650-1 Battery Acid Tester is a handheld battery electrolyte tester designed for measuring the specific gravity of electrolyte in lead-acid batteries. The single-piece, portable instrument provides quick readings to assess state of charge and identify issues such as sulphation or stratification. Intended for use in workshops and mobile service environments, the tester delivers fast, practical information to support battery maintenance and diagnostics.
Advantages

Its compact format supports convenient handling in confined spaces and during mobile service calls. Readings help technicians make informed maintenance decisions by indicating charge level and electrolyte condition without complex procedures.
Suitable for
 Routine battery maintenance in workshops and garages
 Mobile service and roadside battery checks
 Diagnostics of lead-acid starter, deep-cycle, and maintenance-free batteries where electrolyte access is available
 Assessing state of charge and detecting sulphation or electrolyte stratification
Key specifications
 Type: handheld electrolyte/acid density tester for lead-acid batteries
 Measurement purpose: specific gravity of battery electrolyte to assess state of charge
 Form factor: single-piece portable instrument for direct sampling
 Application environment: workshop and mobile service use
 Suitable battery chemistry: lead-acid (including flooded starter and deep-cycle batteries where electrolyte access is possible)
How to use
Access a battery cell vent or remove the cell cap following the battery manufacturer’s safety instructions. Insert the tester’s sampling tube into the electrolyte and draw a sample according to the instrument’s handling method, then read the specific gravity value indicated by the device. Compare the measured specific gravity with standard state-of-charge reference values for lead-acid batteries to evaluate charge level and electrolyte condition. After measurement, return electrolyte to the cell if relevant and clean the tester following safe handling procedures for acidic fluids.
Usage recommendations
Always wear appropriate personal protective equipment, including gloves and eye protection, when working with battery electrolyte. Perform measurements in a well-ventilated area, avoid contact with skin or clothing, and dispose of or neutralize any excess electrolyte per local regulations. Do not use the tester on sealed or maintenance-free batteries where cell access is not intended by the manufacturer.
