Description of 🔋 KZYEE KS21 Battery Tester - Accurate 12V Analyzer for Auto Car Batteries, Health Fault Detection, Cranking & Charging System - 100-2000 CCA, Digital Load Testing

🏆🏆【BATTERY HEALTH CHECK】Applied with the latest conductivity method to measure, the tester will scan the battery and get the results in 3 seconds, including the State of Health, the State of Charge, the Internal Resistance and the Testing Conclusion (Excellent>80%, Passable>60%, Attention>45%, Replace<45%). The Battery Standards includes CCA(SAE), IEC, EN, DIN, JIS#, etc. 🏆🏆【WIDELY APPLICATION】Works on 12V 100-2000CCA lead acid batteries , including Regular Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB. Also, it is suitable for cars, motorcycles, trucks, ATVs, SUVs, boats, yachts, mowers, and even golf carts and lawn tractors batteries. 🏆🏆【CRANKING & CHARGING SYSTEM TEST】Presents you with the test results (actual cranking voltage & cranking time) of the starter system in milliseconds to indicate if the cranking system is working as expected. Also, the battery load tester conducts a throughout check on the 12V charging system to make sure a normal generator output,perfectly working rectifier diode and under controlled charging current. 🏆🏆【SAFE PROTECTION DESIGN】The battery tester doesn’t emit light, heat or spark, and won’t discharge the battery. It also has polarities wrongly-connected protection, over-voltage protection and automatic temperature compensation. What's more,it is safe for you, your cars, your batteries, and battery tester automotive itself. 🏆🏆【EASY OPERATIONS】The strong and lightweight construction, well-arranged keypad, and menu-driven operation make this battery alternator tester easier to operate. The tactile of click buttons give good physical feedback of a positive push, even when working with gloves. Even a beginner can use this car battery tester at ease.

This little thing works great!

I had a car that I thought had battery problems so I decided to take this thing to check the problem. It was easy to connect and easy to read. I did a test and found that the battery is actually good, it's a charging system that doesn't do the job. I'm glad I didn't spend $$ on a new battery first! I decided to try it on a lawn mower battery just to see if it would work on them too and it reads well and this battery is great tested. Cool tool and one I will have for years to come.

Pros
  • cool product
Cons
  • I vaguely remember

Convenient, compact size and ease of use

Just a week ago I was at a friend's auto shop and asked if they had a battery tester. I tried his compact battery tester he has and the battery life is 66% which is not bad for a four year old battery. The one he has doesn't do a charging system test or start test. The reason I bought the KZYEE battery tester is that it does all three tests: battery charging, charging system and starting test. The battery test almost reached the displayed percentage with 2%. The instructions are easy to follow,

Pros
  • Everything is great!
Cons
  • Low Repairability

Ensure a good connection

The first car battery I tried with this tester led me to believe it was dead or damaged. The tester looked at some strange and unfounded readings. 8856 cca for a 600 cca battery that is 5 years old and dead. It was a side carrier battery outside of the car and I eventually realized I might not be getting the best connections. I screwed some new and clean 3/8" x 16 screws into the battery and got good contact. After that the tester worked as expected. The battery then tested 92 CCA, 2% and 11.94

Pros
  • Beautiful packaging
Cons
  • The list will be long.

Seller quick to respond to questions

When I received my KS21 I tested it with two 1 year old batteries. For both batteries, the CCA was significantly higher than the battery label. I was concerned that the device was not working accurately. I contacted the seller who responded in less than 24 hours. He explained that the device worked well and that when the battery was healthy, the meters often showed more CCA than the label said. Batteries are labeled CCA at 0 degrees Fahrenheit, and obviously I haven't come close to that…

Pros
  • Amazing
Cons
  • Some bugs

Provides what you need to know.

I dreamed of a battery that seemed to be running low and wanted to know the true state. The result of the stress test was not clear. Purchased the KS21 analyzer after reading about the benefits of testing with conductive test equipment to get a more accurate indication of actual battery health parameters. Took the battery to the local NAPA with a question for a warranty replacement. NAPA staff tested the battery with their impressive professional analyzer. The results from their analyzer were…

Pros
  • A sea of positive emotions
Cons
  • No indicators
