Battery Tester ARL-BT-302

Battery Tester ARL-BT-302

The ARL-BT-302 Battery Tester is a handheld, quick, and economical device for testing battery internal resistance/conductance, inter-connection strap, and voltage. It helps eliminate weak batteries to ensure optimal performance in your battery systems, including VRLA, Vented Lead Acid (VLA), GEL, and Ni-Cd batteries used in standby critical power systems. It supports a wide test range up to 6000Ah and is capable of accurate, repeatable measurements of battery health.

Key Features

• Tests Internal Resistance and Conductance: Two units in one, with a smart switch to test both internal resistance and conductance.
• Wide Battery Compatibility: Capable of testing single Lead-Acid or Nickel-Cadmium cells or strings, supporting 1.2V, 2V, 6V, 12V, and other customized cell types up to 6000Ah.
• Rapid Testing: Performs fast and consistent tests on single or multiple batteries in seconds.
• Advanced Measurement: Adopts advanced measurement of AC signal discharge to test internal resistance.
• Data Management: Up to 100,000 cells can be stored internally, with unlimited storage via USB drive exportation.
• User Interface: User-friendly TFT touch screen and keypad for alternative operation.
• Rugged Clamps: Includes a three-in-one alligator test clamp with a metal jaw (6cm long, 3mm thick) for quick testing of internal resistance and inter-connection strap.
• Functional PC Software:  Data View software for data analysis, battery condition tracking, and easy report generation in Excel.
• Long Battery Life: Powered by a Li-ion battery (4000mAh) providing 8–12 hours of working time.
