KONNWEI KW600 Car Battery Tester 12V Professional 100-2000 CCA Automotive Battery Load Analyzer and Alternator Tester Waveform Voltage Test for Car/Boat/Motorcycle…

Excellent , way to use & fast Delivety

I used the Konnwei battery tester on two cars (one very old, one brand new), and 4 small lead-acid batteries used in a UPS (Uninteruptable Power Supply). The new car had a battery that was in very good shape, but didn't have much of a charge, as it was sitting at the dealer lot, and was shipped from abroad. The new car was a 2019 Hyundai Kona with a 60 AH, 640 CCA AGM battery, and it was at 100% SOH (State of Health), but at 56% SOC (state of charge). After charging it, the Konnwei unit showed the charge up to 98%. It is important to keep lead-acid cells near full charge, as if they are allowed to sit partially discharged, they will form sulfates on the plates, shortening the life of the battery. The second battery, on a 2003 Hyundai Santa Fe was about 3 years old, and the car isn't driven much, so the battery loses its charge because of typical parasitic current draw from the on-board computer, clock, radio, etc. The pictures show the SOC, SOH, and a photo of the Konnwei connected to the battery with a disconnect switch on the battery. While the battery is good, it shows 82% SOH, as the photo was taken at 28 degrees Fahrenheit, and lead acid batteries don't have as much 'get up and go' at lower temperatures. The four small lead-acid batteries that I checked that came from a UPS were 7 years old, and only showed about 2% SOH, so they were ready to be recycled. I also like the feature where you can get an 'oscilloscope' style display (graph of voltage over time during the car starting up), and so you can see if the battery is getting near end of life, or is still good for a few more years. Both batteries in both of my cars showed good starting performance at 30 degrees Fahrenheit. This is a must-have for folks with cars more than a few years old, as you will know when to replace the car battery before it gives you trouble, and leaves you stranded somewhere. This unit uses a new technology where it judges SOH from the rated CCA (cold cranking amps) and the internal resistance of the battery. An excellent tool to add to your garage.

I found this to be easy to use and the instructions were good. I would have given it 5 stars but the screen is not very bright in sunlight. In addition it worked well on my truck’s flooded battery, but had trouble on my Chevy Volts AGM. The Volt obviously does not have a conventional starter motor and generator. MGA (the generator) functions as a starter for the ICE. It runs off the HV battery, so no typical start chugging involved. Therefore I cannot determine how to check the CCA, and do a thorough analysis of the battery. The book does not address this and I have not heard back from the manufacturer yet. Any thoughts would be appreciated.

Battery Tester was everything it was described to be, packaged very nicely, looks very professional. No internal battery needed just hook it up to your car battery and it comes on by itself. Much better screen than those other testers out there, easier to read and gives you a very bright readout. Measures everything you could want battery voltage, cranking amps and charging status. I have tried a few of the others and this one is faster with the tests results. Unit has a great warranty and you can even update the software on it, unlike most of the others. Case is plastic but it is very solid, it has nice long cables on it and the alligator clips are really heavy duty with great bite. Instruction book is nicely laid out but honestly it is so easy to use you won't need it. Like the others there is no case but the box it comes in is very strong with a nice compartment insert, which is great for storing. This one has everything you could ask for in a tester, don't waste your time with the others. Seller is very professional they know how to take care of there customers.

KONNWEI KW600 Car Battery Tester 12V Professional 100-2000 CCA Well worth the price. Works on lawn mowers so I get peace of mind before taking them into town.

While viewing DIY auto repair channels on Youtube, I came across Conductance Battery Testers. While looking up a few models on Amazon similar items came up such as this Konnwei KW600. I saw some videos and looked at the specs. Obviously, I had my doubts about something inexpensive doing so much. I received the product the next day and tested a deep cycle AGM battery out of the boat, then my car and then another car. It took me more time to open the hood then it did to do the testing. A main feature I looked for was the milli-Ohms to help me determine the health of the battery. This product does it all for testing my batteries, alternator and starter. There may be more expensive one out there, but I can't see what they do that this doesn't. This is almost as much fun as finding Pokemons. I'm looking for more batteries to test. I would recommend this product to anybody who doesn't want to get scammed by a dishonest mechanic/shop. Know what is wrong with your battery, starter or alternator, then find the best person to fix/repair/replace the part if you decide to let somebody else do it. The knowledge will save you and your family $$$. I think anybody of any age could use this device since it is very intuitive. I'm now looking at more of their products for diagnostics.

facil y pratico

Muito bom!

Usage pro, très efficace

Collegato direttamente alla batteria e preciso. Poi fare pure test della carica batterie con vizualizatione tipo oscilloscopio a vedere la forma del segnale. Lo uso insieme a "Doctor 50-Telwin". Per me va bene. Grazie.

Works very well, is very sturdy and easy to use. You get a lot for your money!
