Review: Great Stuff! - Unbelievable! This gaget works really well! I was skeptical at first when getting this product, I was thinking that.... it's not going to be very accurate. It's actually very very accurate! You can see in my picture that I compare the voltage with my high dollar multimeter. The reading came out exactly the same! The other features that I've noticed that it's automatically reading the CCA. It seems like it was communicating with the battery and tells you all of the battery specifications. It's also can do 6 volts as well. The unit itself is not big at all! You can put it in your tool box with ease! It is very easy to use and straight forward. So if you want something that can read your battery voltage and find out the specs for your battery, you need to get this unit. Well worth the money spent! I highly recommended for your garage..... it'll come in handy.
Review: Great Car Battery Tester - I recently received the KINGBOLEN BM550 Car Battery Tester on my car. As mentioned, this tester is compatible with 6V, 12V, and 24V batteries, supporting a wide range of types including regular flooded, GEL, and EFB batteries, making it suitable for cars, trucks, and more. It’s a practical tool that quickly displays the battery’s State of Health and State of Charge, as well as conducting internal resistance and voltage tests. It has a clear 1.8-inch HD screen to show the data, making it easy to understand the battery's condition. One of the standout features is the reverse connection protection, which prevents damage if the wires are accidentally reversed—an excellent safety measure for long-term use. The tester is plug-and-play, requiring only a correct connection to the battery to start working, whether the battery is in or out of the vehicle, or even if it’s dead. The KINGBOLEN BM550 is straightforward to operate. It’s a perfect tool for DIY enthusiasts, garages, and car factories, offering peace of mind by helping to avoid unexpected battery failures.

### ⭐⭐⭐⭐ Basic, but looks like it has the essentials
*by D***. on December 5, 2025*

Very basic battery tester, but will allow testing by CCA or AH capacity ratings so it works on more than just cranking batteries (I am testing non-start rated deep cycles for an electric motor and on-board electronics). It DOES REQUIRE that the battery have SOME juice in it as the unit does not supply its own power. Also, I have not tested it on a weak battery with a bad cell to see if it indicates the error or would just report poor condition. All-in-all, for the low price it is a decent unit if a basic test is all you require. It for sure isnt the one you would use at an auto repair facility, but it did the job I needed to do testing three batteries after sitting idle for more than 18 months. Does NOT come with a case of any kind.
