Received V200 Pro in couple days after order.
Have not had chance to use.

It is a tool everyone needs to save money on expensive trips to the repair shops. This has truly impressed me with all the many options. I know there are bigger bidirectional scanners but this one is affordable and works great. I highly recommend

Tests different vehicle batteries quickly and accurately. Very handy!

Features are all most DIYers will need, would like to see a crank test in motorcycle mode.
Functionality is good, everything seems to work spot on to what I expected and accurate.
Ease of use is right on the money, buttons have an obvious feel and audible click to them.
No battery, must be plugged in with the usb cord or hooked to a battery.
USB offers upload and print features.
As far as value for the money, I’d say that depends on the user, it’s in an acceptable range for most.

The unit has a really bright backlight or interior light? As you can see in the pictures, seems excessive especially at night.

Build quality seems toyish, the backlight, the weight and feel seems like it may not last in a mechanics environment for long. The clips seem ok, but on the small side for what I prefer like clips designed for a hobbyist.

I love this very useful tester, and recommend everyone to keep one of these in your car. I purchased and received it in a few days. I tested two of my vehicles, one auto and one pickup. The results showed a good battery for my truck, however although, operational, my auto battery getting near end of life and will replace before the next winter season. Also, a coworker's car would not start and used the tester, and found out battery was in good condition, only the connectors needed cleaning and to retighten. This saved him the purchase of a new battery as he had planned to do, before using my tester. The tester is well made and very easy to use. It allows for testing while fully connected to vehicle or if removed from vehicle. It provides a good general test and also cell test, giving you a good understanding of the health of battery. Additional testing including cranking, charging and more. Upgradeable software, so it will be good for years to come. The tester is good for various types of 12v and 24v batteries. I will keep this tester in my car for use when needed for my own vehicles, but expect to use it for others in need, as well.

Good Product

Shows exactly what the battery needs—no guesswork.

The BT500 Car Battery Tester is an outstanding tool for anyone looking to stay on top of their vehicle’s battery health.
One of the standout features is its wide compatibility it works on all 12V and 24V batteries, like regular flooded, AGM, GEL, and EFB batteries. It’s perfect for cars, trucks, SUVs, motorcycles, and more. No need to worry about whether your vehicle’s battery type is supported; as long as it’s not a lithium battery.
The reliable performance of the BT500 is something you can count on. It provides detailed insights into your battery's health (State of Health), charge status (State of Charge), internal resistance, and cold cranking amps (CCA), giving you a complete overview of the battery’s condition. This level of detail helps you determine if it’s time to replace or recharge your battery.
The starter and alternator tests are equally impressive. Just remember to turn off electrical devices like air conditioning, headlights, and radios during the charging test for optimal accuracy.
The device also includes advanced safety features like reverse polarity protection, spark-proof functions, and over-voltage/temperature protection, so you can use it with confidence without worrying about mishaps.
Overall, the BT500 is an essential, must-have tool for anyone who values the health of their vehicle’s battery and wants to avoid inconvenient breakdowns. Its combination of ease of use, comprehensive testing capabilities, and top-notch safety features make it an excellent investment for vehicle owners of all kinds.

The shipping of this tester was really fast, received tester in 3 days to Hawaii. It came in a box and the box was packed well to prevent damage. Battery tester's quality is excellent! The tester is thick plastic, the cord does not retain memory when bending, and the battery clip open wide to make sure you have a good connection. The price of this tester is awesome!! It has many features for it's super low price. I have bought a lot of meters and testers in the past. Some only check voltage, a few is a percentage and voltage meter, and usually the load tester is separate. I would carry at least 3 meters to check voltage, load, and percentage. This BT500 can do all those tests and more. It is very simple to set up by connecting the red clip to the positive post and then the black clip to the negative post on your battery. It turns on and the displays show you your options. There are 3 lights to show you off hand your batteries condition. Green is good, yellow means you need to charge, and red is charge and if it can't be charged, it is time to get a new battery. You can verify the lights by going to the testing options. The menu is easy to follow. It will ask you 12 or 24 volts, what type of battery, and the cold cranking amps. The label on the battery has all this information. This tester will tell you the volts, amps, state of health, state of charge, and provide you with a waveform. You can have a tester that tells you your battery has 12 volts but that is meaning less. You need to put a load on the battery and if you have a weak battery with less then 10.5 volts, your car will have a hard time starting if it starts at all. the BT500 tester will also indicate how much your alternator is putting out. You usually need around 13 to 15 volts for your battery to be recharged. I really do not have anything negative to say about the tester itself because it is accurate, durable, and it does everything the company says it does. Very easy to use and very compact.

Two things that does not affect my rating because it is not negative. One, I wish it came with a little plastic carrying case, but that is no problem because you can always find one. Two I wish it was touchscreen and that is not a problem because the buttons are marked clearly and is very easy to use. I have tried this tester on my boat, riding mower, motorcycles, and cars and trucks. What I found out on my outboard motor is that the motor has no rectifiers and parts to recharge the battery, and my riding mower had the ability to recharge the battery except when I flipped the mower over it lost its ability to recharge. Now I know exactly how long my boat battery will last before I leave the dock. Being stranded on the ocean due to a dead battery is no fun. All this time I thought my boat battery was being recharged when using the boat. This tester may have saved me from being stranded with a dead battery. I do not think this tester is waterproof so if you take it on your boat, make sure to keep it dry. I am impressed with all the features this tester has and what it can do.

BT500 is easy to use and gives accurate results. I always know my battery’s status in seconds.

Great for any electrical work. Makes your work cut in half by finding wiring issues plus jump wires and components on your vehicle. Can’t wait to use it for my next repair.

Works just great. Easy to use, easy to read and pretty good instructions. I am happy with this.

This works pretty well. I had a faulty battery that would eventually fail, so it was useful to check its condition. Easy to use too, I'm happy with the results.

These are one of the best tools I’ve ever used. I used it to check if there was any wiring problems in my minivan. It helped me detect the exact location of trouble on wire . It came with so many accessories. I can use it for so much - checking voltage, electricity, battery levels component amper , wiring issues, and much more. It comes with so many different plug types. The wiring is also long . The best part is that it even comes with an extension cord. It even has LED lights at the end, which saved me from using my own flashlight. So convenient.

I have used the previous version for some time now and it works great so I ordered the newest one. I was not disappointed. The swivel screen is much handier than the fixed screen and the circuit breaker finder works flawlessly.
