KONNWEI KW600 12V Automotive Battery Tester Professional 100-2000 CCA 220AH Car Battery Load Analyzer and Alternator Tester for Car/Boat/Motorcycle

I have to confess that I was dubious when i purchased this. How could a battery tester at this price be good enough. Well I didn't have to worry, it's brilliant. The last battery tester I bought was well over £200. This does more at a fraction of the cost. Is it accurate? Yes it is. Is it easy to use? Most definitely. I really can’t think of any negatives. If you want an accurate, simple to use battery tester this is the one.

I ordered this product and received this today and i can say i am very happy. First of all it arrived on time with no issues. i updated the software very easily and smoothly. Today i tested this on three cars in my family and i am very happy with the results and information provided by the battery tester. Wonderful little gadget, easy to use and would recommend to anyone looking to buy!

For automotive tools go this may not beexpensive but wish I had this at the beginning of pandemic lock downs rather than towards the end. Lack of use of cars meant the 12V lead-acid batteries ran down rather quicker than anticipated. Bought and replaced battery on wife's car. As my car had a recent battery change was disappointed with it so sent it back for investigation to see if mine was a dud but before that had to get a battery for the car so as to avoid internal rechargables batteries (there must be many for the various sensors) from going flat. The battery dealer rejuvinated the first one. So now have 3 batteries between two cars so wish I had this before we inadvertently drained the batteries. Anyhow, this meter is easy to use. However, probably due to inexperience rather than fault of the meter (or the car battery) the results were not consistent, or so it appeared. However, after lock lodwn ended and cars being used weekly (or put on a charger weekly) results became more consistent. Whether batteries were healthier, me being more experienced in using the meter, not conclusive. All I can say is the meter would give me earlier warning to go get the battery topped up on the charger whereas previously I relied on a multimeter only, so guess the multimeter was late to give me a warning. If your battery is nearly dead, then this won't work as it takes energy source from the battery you are testing to pwoer it up.

I needed a battery tester that I could quickly use every day and rely on its diagnosis of car Batteries/Alternators. I have tested on many batteries and alternators over and over, known good and bad batteries and every time it comes up with the correct diagnostic outcome. Very confident and pleased with this tester. A little on the small side but I purchased a Fluke case for it which holds it firm and stores all the leads.

We purchased this battery tester in a professional capacity for our engineers out on site and have not been disappointed. Used daily it has performed very well. The variety of functions have been well received by the guys and they are using most of them, including the download to their laptops. The small size has not been a problem and we intend purchasing more for the rest of the service team.

Simple to use, compact and amazingly useful. Great item, definitely recommend this battery tester in our current environment with restricted travel being a major issue to car batterys recently.

Had been having problems with battery draining. supposedly checked by garage who found no fault. Ran tests and found battery was sulphated and not fully charging and probably discharging quicker than it should. Starting from no knowledge of car battery testing etc. got the results I needed in less than 10 minutes after reading instructions, set-up and running tests.

Please see attached photos. The same battery at the same time. Measured according the provided manual and instructions on screen. Now is battery ok or no? I still don't know. I can see that after removing surface charge (per instructions on screen) the longer you would be setting battery parameters the more voltage your battery would recover and this will affect displayed result. Returning as software + manual are note providing a way of reliable checking the battery with consistent and repeatable results. Maybe if you are expert and know how to measure properly then it may be device for you. If not, then you would have troubles.

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!
