TecMate Cranking And Alternator Tester

The TecMate Cranking And Alternator Tester is the ultimate pocket tester for on-vehicle battery performance and alternator voltage testing that every gear head should have.

Easy to use. Connect clips to the battery or connect to an installed SAE battery lead, then check battery charge level. A low battery cranks poorly. Start engine. OptiMate TEST records and indicates (for 20 seconds) the lowest start volts. With engine running, verify charging voltage from alternator and voltage regulator.

Low charge voltage causes poor battery performance. Too high charge voltage causes excessive gassing and will eventually damage a lead-acid battery. Too high charge voltage is fatal for a LiFePO4 starter battery.

Features:

  • Microprocessor accuracy
  • Easy to follow instructions on rear panel of the tester
  • Industry standard SAE connector
  • 40″ (100cm) battery clip set
  • Fully sealed
  • Premium tester designed by TecMate
  • 3-year limited replacement warranty
