Optimate test state of charge | TECMATE

Product description

For use on any vehicle with a 12V lithium battery system – Any battery size, any charging system. 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.
