Tecmate TS-121 Mini - Battery & Charging System Analyzer

The easy- to-understand battery & charging system analyzer for all 12V starter batteries. The TestMate mini is more than just a voltmeter, it’s a super fast recorder of instant volt drop during ‘engine’ cranking – the best indication of a starter battery’s ability to deliver power when the engine needs it most. Once the engine runs it checks if the charging system is able to bring the battery back to full charge. This unique, handheld on vehicle battery & charging system tester:

• Checks Battery Voltage – Your battery’s ‘rest’ voltage is an indication of battery health.
• Checks Battery Starting Power – A reading in the red zone indicates a problem!
• Checks Vehicle Charging System – Is the charging system causing the problem?
