The Matson E55-2012 is a professional grade carbon pile load tester designed for 12V automotive battery and starting system diagnostics. Delivering up to 500 amp load capacity, it simulates engine cranking to reveal weak batteries and marginal starters quickly and reliably. The tester uses carbon pile technology with variable load control to apply a controlled current while monitoring battery voltage and performance, making it ideal for workshops and mobile technicians who need a fast assessment of battery condition under load.

• Maximum load capacity 500 amps for realistic cranking simulation
• For 12 volt systems only
• Carbon pile variable load for precise load application
• Integrated meter for voltage and load readouts
• Heavy gauge test leads with insulated clamps for secure connections
• Rugged portable construction with carry handle for workshop or mobile use

This tester helps identify weak cells, poor charging and starting system faults and speeds up diagnosis and repair. Follow safe connection procedures and observe meter readings during load application. If using for a specific vehicle or battery type, use the Parts Checker to confirm suitability before purchase.
