Tecmate OptiMate Battery Cranking & Charging System Tester (TS-121)

The ultimate pocket tester for on-vehicle battery performance & alternator voltage testing that every service technician or 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 (starts engine) poorly.
• Start engine. OptiMate TEST records and indicates (for 20 sec) the lowest start volts.
• With engine running, verify charging voltage from alternator and voltage regulator.

TIP: 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!

• Microprocessor accuracy.
• Easy to follow instructions on rear panel of the tester.
• Industry standard SAE 2-pin connector.
• 40? / 100cm battery clip set.
• Fully sealed.
