OptiMate 12V Battery Tester TS-121

This pocket-sized premium tester designed by TecMate is solid, reliable and easy to use. Simply connect the clips to your 12V LiFePO4 battery or connect to an installed SAE battery lead, then:

  1. Check battery charge level. A low battery cranks (starts engine) poorly.
  2. Start engine. The OptiMate TEST unit records and indicates (for 20 sec) the lowest start volts.
  3. 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!
