Car Battery Tester, TOPDON BT600 12V, 12V/24V Cranking Tests and Charging Alternator Load 100-2000CCA Digital Battery Voltage Tester, 3.5" Screen with Built-in Printer

very good tester, well made and all parts have good quality. Great instruction manual and actual testing procedure from the tester are very clear. Reading were accurate and matched to some tests done with a multimeter

I use it on a daily basis. Works great and very accurate. Great value for the price

I’m so glad I chose this Battery tester. It’s very easy to use. The color screen is easy to read. The printer is a game changer, I can print all the tests and use them to help diagnose and put with customer invoices. The information it gives for the price is remarkable. I needed one that would show me the health of the battery and be able to measure cca of the battery when tested before re-charging. Cranking test and charging test work great and gives great information including a ripple mV charging test. Cranking test gives cranking voltage and cranking time. I really like that it gives an Internal Resistance of the battery too. Very Happy with this tester.

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.

Work better than snapon

Great product easy to use automotive technician will love this

I have several vehicles and this device allows me to keep an eye on how the batteries health. When one is getting weak I can replace it before it leaves me stranded. I can also determine how the charging system is doing.

I work at a Honda dealer and love this tester it’s quick and easy to use definitely recommend this.
