The ultimate pocket tester for on-vehicle battery performance & alternator voltage testing with either 12V lead-acid or 12.8V LiFePO4 starter battery – Easy troubleshooting from cranking to charging!

Connect the 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.


FEATURES

• For vehicles fitted with 12V AGM, GEL and STD lead-acid or 12.8V LFP / LiFePO4 starter battery.
• As easy as 1-2-3, connect to battery, check state of charge, start engine tester displays cranking voltage and vehicle charge voltage simultaneously – 15 sec is all you need!
• Display cranking volts down to 6V and charge voltage range up to 15V – Check weak battery or overcharging!
• Easy to use! Connect with the included clips to the battery or connect to an installed SAE battery lead.
