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!

  • 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.

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!

LENGTH: 40″/100cm

CHARGE CONNECTOR (INPUT): 2-pin SAE (+set batteryclips)

My last Timex and why.
Color: Black/Gray/Digital, Color: Black/Gray/Digital
New edit. Upon further reflection, I’ve only had, a couple of exploratory years with Swatch excepted, Timex watches. My first one was when my mother replaced the Chicita Banana “tickity tock” sticker with a real Timex wind up watch before my first Cub Scout camp. In addition to many other Timex products, I’ve had these Ironman watches for the past 25+years. Usually the band wears out and can’t be replaced after three or four years. This particular watch fell apart less than six weeks old. It wasn’t hit by impact. It just came apart while I was driving down the road. I wonder if they’ve changed their manufacturing process. See photo for details. What is truly infuriating is that rather than replacing it, because it is truly a warranty issue, the told me to ship it to their offshore repair facility (which could take 3-5 months) and pay what might be half the value of the watch. Things happen, but the intentional friction they have created to avoid their obligations borders on malpractice and speaks to their indifference toward customer experience and subsequent lifetime value.

As expected
Color: Gray/Gray/Digital
Just an old school digital timex. Tried and true. Has both 12hr and 24hr function on the time setting. Has a standard stop watch and timer. The battery is great, just as it always is on a timex. Good water resistance and very easy to use. Overall very good watch for the price!

Can’t read numbers

Love the Timex Ironman Shock watches!!
Color: Black/Black/Digital
I really like the Timex Ironman Shock watches. They are very durable and reliable. Simple to use and modeled after the. Original Ironman watches of the late 80s and 90s. Buttons are clearly marked and easy to press. They used to make many colors of this Shock model of the watch inc a cool shiny red color my wife still has . I have been a runner many many years and at 65, am still out although a lot slower than my 20s. But Timex Ironman watches have. Been my constant companion on the roads and track for 35 years now.
