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. ## Features - 【6V 12V 24V Battery Tester】 KINGBOLEN BM520 car battery tester can test all 6v 12v 24v 100-2000 CCA lead-acid batteries, including Regular Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB batteries for cars light trucks SUV ATV boats motorcycles etc. Based on CCA, BCI, CA, MCA, DIN, IEC, EN, JIS, GB and SAE battery standards.

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 BM520 6V 12V 24V Car Battery Tester, 100-2000 CCA Automotive Load Tester Accurate Digital Auto Battery Analyzer Cranking and Charging System Tester for Cars Trucks SUV Motorcycle - Watris Veiyi Rapid Battery Hydrometer Tester, Deep Cycle Battery Tool, Fast Detection Tool for 6V 12V 24V Golf Cart Battery System (Inhalation) - LubriMatic 75-033 Battery Filler w/ Rubber Spout, red, 1 Count (Pack of 1) --- ## 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/625971339-kingbolen-bm520-6v-12v-24v-car-battery-tester-100-2000](https://www.desertcart.vu/products/625971339-kingbolen-bm520-6v-12v-24v-car-battery-tester-100-2000) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
