## Features

- 🚗【Auto Car Battery Tester】KINGBOLEN BM550 battery tester can test all 6v 12v 24v 100-2000 CCA car batteries, support 2Ah-220Ah(need to enter the corresponding CCA value on the battery), including regular flooded(Regular battery), AGM flat plate(AGM tablet battery), AGM spiral(AGM winding battery), GEL and EFB batteries, battery analyzer for cars trucks SUV ATV boats motorcycles vehicle etc.
- 🚗【Quick Tests & Accurate Data】The results of the battery test are based on the CCA standard, which can be quickly and accurately displayed on the 1.8-inch HD screen, allowing you to quickly know the status of the battery. The clip is made of pure copper, with a strong bite force. The red wire is connected to the positive "+", and the black wire is connected to the negative "-".
- 🚗【Multifunctional Battery Analyzer】KINGBOLEN BM550 car battery analyzer can quickly and accurately display multiple data of the car battery. It can test the SOH (state of health) and SOC (state of charge) of the battery, easily test 100-2000 CCA, internal resistance test and voltage test. With our battery tester, you can easily grasp the current state of your car battery and avoid accidents.
- 🚗【Plug and Play】It is simple to use, just connect the clip of the battery tester to the car battery correctly and it can start working, whether the battery is in vehicle or out of vehicle, or a dead battery can be tested.Start your test now!

## 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.
