Review: Another Great tool u need - Worked as intended. Another electronic tool you definitely need if you’re a person eho enjoy’s DIY on car maintenance. Cable and alligator clips are sturdy. This is a compact size easy to hold and handle unlike others which are expensive and bulky
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.

## Questions & Answers

**Q: Can this product be used on a deep charge golf-cart battery?**
A: It can only be used to detect the car battery, not to charge the battery. Our BM550 battery tester can test all 6v 12v 24v 100-2000 CCA car batteries.

**Q: Will this tester accurately measure internal resistance in a 12V deep cycle lawnmower battery?**
A: It measures 6v 12v and 24v system batteries. It does read internal resistance but I’m not sure how accurate that particular measurement is because I have never compared this other battery testers.

**Q: How do i know if my car battery test result soh, soc, and cca numbers are good or not?**
A: Not sure about social or soh.  Cca is one of two prompted questions.  If you are not sure of target cca, you might need to look up you battery model and confirm.  Once you input cca, the meter goes through a test cycle and gives you actual cca.  It decides good or bad based on the cca you input.

**Q: Will it give the remaining ah  amp hours for batteries or just cca?**
A: Reported values are CCA's.  Remaining AH isn't part of the output.   You could, roughly, determine the remaining AH through the SOC (State of Charge).   For sake of example, if the battery is a 10AH battery, and the SOC = 80%, then you have, roughly, 8AH "left" in the battery.   That's not exactly the best way to derive that but it's a ballpark.  The element that isn't taken into account is why the battery SOC is where it's at (e.g. age, degradation, discharge due to parasitic draw, etc.).  Depending on the combination of those factors will determine what the actual AH capacity is, at that SOH and SOC.

### ⭐⭐⭐⭐ 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.
