TopDiagBT200 Pro Car Battery Tester, 12V 24V Load Tester, 100-2000 CCA Automotive Charging Cranking System Tester Digital Auto Battery Analyzer for Car Truck Motorcycle SUV Boat (BT200 Pro)

Quick and easy to setup, does a health check, load test, state of charge, alternator, and wave test. I Compared it against a voltmeter, it is very accurate regarding the state of charge and provides an excellent assessment of the battery condition. The functions are clearly marked with the following symbols, Quick, Standard, Start, Charge, Wave test, and setup. No batteries required, just connect to the vehicle negative and positive terminals.

Very easy to use item that gives a reliable reading on the current state of a batteryYes it does test 24v charging tooNo it doesn’t test 24volt battery set up IE 2 batteries at once, batteries need to be tested one at a time.I’ve not tried it on 6v .Tests..I went to a friends workshop and tested it on brand new batteries, mediocre batteries and knackered batteries, also knackered batteries that had been charged, I am amazed at how accurate this unit is.To use, enter the amp hour EG 120 AH the follow the instruction to perform the tests, it even tells you how old the battery is .. 100% is brand new, 45% is obviously old. I will add pictures later.The charge test seems a bit daft, rev the engine to 2000 RPM and switch the lights on for 3 seconds then back off, I understand why you do it but your just as well off with an Amp meter and volt meter for that.Battery testing though… it is extremely accurate.NB to properly test batteries you need them on trickle charge over 24 hours, leave them for 24 hours and then test them, it’s rare people ever do this but that is how you are supposed to test a battery properly.

Really accurate tester that gives you warning of low charge state before your battery is completely discharged and your car fails to start. Feed in the type and basic specifications of your battery and the tester will give you an accurate measure of the state of charge and battery health.

as long as you input the battery details you are ok good tool

Have a new 1 year old car which reviews say needs new battery after one year . Still showing 78% so turning off stop start doing a good job . So many electrics on modern cars turnig engine off everytime one stops just run’s battery down .

Very easy to use.Clear displayGood value for moneyTested a number of batteries now and results do appear very accurate.Instructions are a little basic but the menu is fairly self explanitaryOnly bit of advice I would like to pass on is if you pick GB for battery type you can set Amp Hour Not the CCA cold cranking amps

Wow, how complicated can 1 tool be. Unless you have a degree I suggest getting something better

Just received this less than 24 hours after ordering. I use alot of leisure batteries ( 4 or 5) to provide power for my remotely parked caravan, including a 12 volt fridge etc. I use a couple of solar panels to keep me topped up. The problem is, I never know what state of discharge they are in after extended use, and which battery is most in need of charging. This tester provides me with a fairly accurate reading. Also, an indication of the state of health of the battery. It works using CCA & also using AH ( quick check).Early days, but appears to be just what I've been looking for.

This thing works great multiple screens in color gives you multiple readings for the price it's good

Absolutely the best bang for your buck! Had some doubts buying this as it’s only 50$. But those doubts are out the window. Works fantastic, great quality, very easy to navigate. I’ve used Snap On AVR testers and I prefer this indefinitely.

The media could not be loaded.  Très content : simple d'utilisation et résultats rapides. Il permet aussi (modestement) de diagnostiquer un problème d'alternateur.EDIT : Sauf qu'il est tombé en panne après quelques semaines, impossible de le refaire fonctionner

He revisado las baterías de todos los coches de la familia y hemos descubierto que alguna ya está mal y sería mejor cambiarla antes de que muera. Creo que es un aparato bastante útil y por el precio que tiene merece la pena tener uno a mano para no llevarse la sorpresa de quedarse sin batería.

Needed to run some tests on the car battery and decided to give it a try.Most important - it works overall.It can test the batteries and from what I can tell it is reasonably accurate. The results are close to other testers. I'm saying close - because they differ from test to test but they are in the same ballpark.From time to time you'd get results that are totally wrong and don't make any sense but disconnecting and reconnecting the tester seems to fix the issue.The manual is lacking. It tells you how to use some of the functions which is not really necessary because you will see the same prompts on the screen. What I found missing is some of the additional info that would be really nice to have. Like for example the explanations regarding some of the measurements and value ranges.Screen is readable and it is easy to use. Overall it's not a bad device but not perfect either.
