Battery Acid Tester Jonnesway AR030001

The Jonnesway AR030001 handheld battery acid tester is a portable diagnostic tool designed to measure the specific gravity of electrolyte in lead-acid batteries. The device helps evaluate the acid level and relative charge state of battery cells, providing a quick indication of battery condition for automotive, motorcycle and other lead-acid battery applications. Its compact size and simple operation make it suitable for routine maintenance and on-the-go inspections.

Advantages

This battery acid tester offers straightforward, manual measurement of electrolyte specific gravity without the need for vehicle disassembly. The handheld design enables easy access to battery cells and the transparent fluid chamber allows clear observation of the test sample. The device is lightweight and portable, allowing technicians and vehicle owners to perform quick checks in workshops, garages or roadside situations. Measurements provide practical data that can inform maintenance decisions and help detect weak or sulfated cells.

Suitable for

• Routine maintenance of automotive lead-acid batteries
• Checking motorcycle and small vehicle batteries
• Inspection of battery banks in backup power systems
• Pre-purchase battery condition checks

Key specifications

• Measurement type: specific gravity of electrolyte (acid density)
• Design: handheld, manual hydrometer-style tester with transparent chamber
• Application: lead-acid batteries (flooded/wet cell types)
• Portability: compact and lightweight for field use
• Operation: simple sample suction and reading of density value

How to use

Ensure the battery area is well ventilated and remove any cell covers as required by the battery design. Insert the tester’s tip into the cell electrolyte and draw a sample into the transparent chamber according to the tool’s operating method. Observe the float or scale inside the chamber to read the specific gravity value and compare it to the appropriate range for the battery type. After testing each cell, safely return electrolyte to the battery if required and clean the tester following the manufacturer’s care guidelines.

Usage recommendations

Use appropriate personal protective equipment such as gloves and eye protection when handling battery acid. Test cells one at a time and avoid cross-contamination between cells. Perform measurements when the battery has been at rest or after a short recovery period following charging or heavy discharge for more consistent readings.
