Description of ๐Ÿ”‹ OptiMATE TEST: 12V Battery State, Cranking & Alternator Performance Analyzer - TS-121

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.; Verifies charging voltage when engine is running.

Actually, I can't say that I gave him a good test.

Actually I can't say that I tested it well. This assumes that the two cars that don't have headlight problems also don't have codes. But in that respect it worked.

Pros
  • Delivery was very fast
Cons
  • 0

Stable readings are best in a battery tester

Very stable readings (all solid state). I used it to test the self-discharge of a LiFePO4 battery. Assuming the battery voltage remains constant, the last 40 daily readings have been the same (within 0.1V).

Pros
  • Nice packaging
Cons
  • There are disadvantages

Mini voltmeters and battery charging systems

Delivered on time and works exactly as expected. Buy cables that are permanently connected to your battery so you can just plug them in and then use them to test your battery and charging system once the engine is running.

Pros
  • Easy to install
Cons
  • Frequency

Great tool for battery testers

Why did I buy this tool? The voltmeter shows the same. The graphics on the front of the instrument are the reason I bought it. You don't have to look up the specifications for each battery type, lead-acid, AGM, gel or lithium. It sits right in front of you and makes the analysis very fast and accurate.

Pros
  • Sturdy construction
Cons
  • Long delivery time

Really does what it says on the tin

Simple product, does the job well. A small problem - the cable is not very long. So for my trunk mounted battery I can't get the gauge to the dash to see it. I mounted it on the trunk lid and could see it in the rearview mirror, upside down but still clear. It takes the guesswork out of diagnosing the charging system and battery condition.

Pros
  • Very good price
Cons
  • Not bad, but...

Revainrating 5 out of 5

Ease of use and accuracy.

Easy to use. Leave the voltmeter on the shelf and just use this tool. It is essentially a voltmeter but uses LEDs to show voltage and therefore acceptable operation of the battery cranking voltage and engine charging system. Use it together with a portable battery tester and/or a battery load tester like a coal heap charging box and you will get a 95% accurate car system diagnosis.

Pros
  • Slim design
Cons
  • Big and bulky

Small and Light: Tools and Equipment

This little block looks like plastic but is as strong as it should be. Works right out of the box 1 shows battery status after plugged in 2 then shows how good the battery is in terms of braking performance (how good the battery is at giving you power when you start the car) just how long you can the sound you hear when you press the start button or turn the key to fire the engine3 indicates how well your alternator is charging the battery. Use this if you are having trouble starting your carโ€ฆ

Pros
  • Absolutely Amazing!
Cons
  • Empty

Great tool! good for diagnostic, testing and measuring tools

Almost no car today is equipped with a voltmeter that continuously measures the battery voltage. Digital voltage indicators are available as an option and are easy to install. But even if you have an aftermarket digital voltmeter, they only retain their readings for the display update time, which is a mere fraction of a second. Since the lowest starting voltage occurs very quickly, the digital voltage display cannot reliably detect and hold the lowest voltage the way the Optimate does. THIS ISโ€ฆ

Pros
  • Good price
Cons
  • Some problems
