The ultimate pocket battery charging tester for on-vehicle battery performance & alternator voltage output testing.

Suitable for use with both 12V lead-acid and 12.8V LiFePO4 starter battery – Easy troubleshooting from cranking to charging!

  • 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 the battery charging tester to your battery, check state of charge, start engine tester displays cranking voltage and vehicle charge voltage simultaneously – 15 seconds is all you need!
  • Display cranking volts down to 6V and charge voltage range up to 15V – Check weak battery or overcharging with this Battery charging tester!
  • Easy to use! Connect with the included clips to the battery or connect to an installed SAE battery lead.

Easy to use! 

  • Connect clips to the battery or connect to an installed SAE battery lead. Connect clips to the battery or connect to an installed SAE battery lead.
  • Check battery charge level. A low battery cranks (starts engine) poorly.
  • Start engine. OptiMate Battery charging tester 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!

Great product

Great product. Easy to understand and use. I have it hooked up to my bike, which has a lithium battery and it’s working like a charm.

OptiMate Lithium 0.8A LiFePO4

All seems good, hard to give a accurate review in the few weeks that I’ve had it but it’s working as expected.

By far the best charger we have in the shop. Was amazed at two lipo battery's that were both bellow 0.5v and both were able to be reset and charged and now working as new in their respective bikes. The added bonus is the power supply function for when we are flashing ecu's or running diagnostics on Ducati's we can maintain full power to the bike without the need to run slave batteries and chargers.
Perfect for our shop and diverse range of bike we have to work on.

Thanks Darren.
