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.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Stuff! *by M***T on November 6, 2023* Unbelievable!

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. ## Frequently Bought Together - KINGBOLEN BM550 6V 12V 24V Car Battery Tester, 100-2000 CCA Voltage Tester 2Ah-220Ah Internal Resistance Tester Accurate Digital Auto Battery Analyzer for Cars Trucks SUV ATV Boats Motorcycles Vehicle - Battery Restore For Lead Acid Batteries - Made In USA - 64oz Formulated Solution Extends Battery Life & Expands Charge Capacity - Safe & Effective For Golf Carts, Motorcycles, Boats & ATVs - Non-Toxic - Watris Veiyi Rapid Battery Hydrometer Tester, Deep Cycle Battery Tool, Fast Detection Tool for 6V 12V 24V Golf Cart Battery System (Inhalation) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/418733428-kingbolen-bm550-6v-12v-24v-car-battery-tester-100-2000](https://www.desertcart.vu/products/418733428-kingbolen-bm550-6v-12v-24v-car-battery-tester-100-2000) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-06*
