TOPDON BT600 Car Battery Tester

If you're looking to test 6v batteries separately, this isn't for you. At the time of my purchase, I was just thinking about all the 12v batteries I have in all my vehicles and toys (as my wife outs it). I purchased this piece of equipment in May of 2024 and totally forgot I had it until recently when my truck wouldn't start. Then I had an aha moment and remembered that I had this battery tester. I found that one of the batteries in my truck was bad. I also tested my other vehicles and found that I have two more batteries in other vehicles that will probably need to be replaced when the weather gets cold due to their age. Unfortunately, I can't test my 6v deep cycle batteries separately since this tool won't test 6v batteries. Anyway, this battery tester can test any 12v battery, along with a few different testing modes/applications and various types of batteries. I really like this battery tester since I no longer have to take the battery to somewhere else to get it tested. I can also print the test results and keep those results either with the tested vehicle or a file folder. Unfortunately, you have to record the vehicle tested, the date of the test and whatever info you want to write on the printed test receipt to keep test results straight. Would I buy it again, most likely, but would like to have a battery tester that could also test 6v batteries. TOPDON has a BT600 Plus which can test 6v batteries too. Testing is very simple and from what I can see, it's quite accurate. Keep in mind, you should charge your battery for 24 hours or at least till you know your battery is completely charged before testing.

Works just as described. Easy to setup and use. Printing were simple. Helps with learning about your battery. The screen is big enough and clear to read.

Super quick and easy to use! It can test several different types of batteries. I elected to use it over our interstate tester at my shop. Reliable results, and my customers appreciate the printed receipt every time.

For years, I used a multimeter to test batteries. Which was ok except I needed someone else with me. I found this, was intrigued by it, so I ordered it. I got it. I unpacked it and everything you need was in the case. I was expecting a hard case but it came with a zipper soft case. It is as big as a OBD reader that your mechanic would use. The display is relatively easy to read in various angles ( more on that later). I tested it out on my Grand Cherokee. If you never tested, or replaced your car battery before- read the instructions. I connected the leads and went inside. This is where it lost a star. The lead wires are about 1 foot short. I prefer an additional 2 feet. So I had to roll down my window in order to use it- wouldn’t have been bad if it was warmer than 10 degrees Fahrenheit outside. Because of this, I had to hold the reader in various angles to accommodate the testing. The testing process is pretty straightforward. The instructions come on the screen for each test. It is able to print the results after each test which gives you a record. I had access to another vehicle that was experiencing battery issues. Did the same test- only to diagnose that the battery needed a good charge ( since it is not driven much and the colder temperatures don’t help). So it saves some money ( ~$200ish) car batteries are not cheap. Definitely something to buy for home mechanics.

Best purchase good quality for the price. Works great recommend for purchase for personal use as well as business.

This thing is awesome. I’ve used it multiple times. Couldn’t be happier with it. Got it at a good price. It was on sale so far. I’m very happy with Topdon products that I have tried.

I have used it a few times and seems to be a quality battery, charging tester. I really wanted a printer option. I paid 450 dollars for a basic snap on tester and it has no print option. This Topdon starts quickly, easy to use and I can print the results for battery warranty. I would recommend.

Really works great use it everyday many times a day
