So when I got the tool, my first thought was, it was not gonna be very accurate, but to my surprise, this tool was extremely easy to use for testing batteries and very accurate!! It also test the starters and alternators for load/ripple. Absolutely amazing deal for the money. Testers that do this many features typically run upwards of $150 and if you want printer with it, obviously it would be that. My only complaint would be that it feels very light and a little bit flimsy so if it fell on floor It would possibly break easily. Lastly, the complaint I have is for the screen. When using outside on a sunny day, there is a lot of glare and it’s very hard to see but if used indoors, it should not be a problem. It would be nice to have some sort of screen or be able to turn up the brightness perhaps. Other than that less than $50 I don’t think there’s anything Anyone could complain about this thing is fantastic and very quick!!! I’m thinking of keeping this in my shop for a bit just to Perform. I’m surprised. I’d rate it 4.5/5 Review: I like it. I did a comparison with an analog.... - First off, I'll say it does have two things I'd like to have better. The backlight on the screen is weak, especially working in the sun it's hard to see. I also think it would be better if this had an internal battery, as it depends on the car battery for power. However, this is a functional, easy to use tool to have around. I love that it comes in a carrying case. It's going to more portable than my analog tester. In my comparison against the analog tester, it was accurate in it's measurements. It will do a battery health test, charging test, and starting test. Would I buy it again? Yes - but I could have survived fine with my analog tester only. So I will recommend this if it's your first tester, but if you already have an analog unit, you're probably fine without. ## 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.
