🔋 KONNWEI KW208 12V Car Battery Tester: Reliable Digital Auto Battery Analyzer for Car, Truck, Motorcycle, Boat, and More Review

I have a KW208. 1) No need to install battery. So I think it can measure a partially discharged battery as the tester needs power. This may be a scam for some. On the other hand, this can be a plus since you don't have to worry about the tester itself. 2) This model doesn't have a download option, but it's not a big deal for the homeowner. So it works, but you need to know the car battery type, CCA and tester functions.

I have several cars, a boat, a garden tractor, etc. and I wanted a simple device that would allow me to check the SOH, SOC and CCA of the batteries of these vehicles, especially when they are running during be stored during the winter months. KONNWEI KW208 does everything I wanted very well. It's easy to use and makes a big difference. The ability to analyze demarcation systems is a huge bonus. The manual could have been written a little better, but I suspect most buyers of this type of product

This battery load tester provides simple instructions for checking the condition of a CCA battery compared to when it was new. I bought this to test a 6 year old Optima battery that was dying. After charging the battery and comparing it to a one year old battery purchased at Walmart, I was surprised when the tester showed that both batteries were basically the same condition. From now on, whenever I need to buy a new battery, I'll take it with me to check the status of the "new" battery. I…

After reading the reviews of Revain I decided to give it a try. I do a lot of auto work myself and this is the easiest battery tester I've ever come across. I recently bought the KW208 and tested three batteries with it. I first used my voltmeter to get a reading before using the KW208. Surprise. I got almost identical readings between the two instruments. It was very easy to use and gave accurate results. The included step-by-step guide helped to optimize the product usage and purpose. This…

I'm an electronics engineer and automotive systems expert. So when I say I'm impressed with this review unit, it really means something. I've tested it with three different batteries that I've already run manual stress tests on to determine their health, state of charge, and CCA (one new battery, one used but good, and one defective); and it correctly identified the status of each battery. It has menus that are very easy to navigate and can run many tests in addition to the most important…

I mainly use this to test 12v AGM batteries. This worked well for most batteries and most car batteries, but ran into a problem. When I applied a slightly overcharged 12 volt battery that charged to 13.3 volts it showed -0.24v and got stuck there and hasn't tested the others since. Thinking I had a broken one, I ordered the same one again. The new one did exactly the same thing. After a few days the tester worked again but was afraid to test batteries over 13.3V. Since the charging system is…

Pros: -- Works as advertised. Calibrated for different types of batteries - traditional flooded, flat AGM, wound AGM and gel. - Measures both state of health, state of charge, cold cranking current, internal resistance as well as summary feedback such as "GOOD - RECHARGE", "REPLACE" or "BAD CELL" etc. - Supports autonomous battery measurement as well as in-car. in the latter case, the starting and charging behavior as well as a graphical representation of the voltage over time (to assess the…

Initially I liked this device. It has good build quality and looks well made. When I first plugged it in, I was told to replace the battery and that my charging system was fine. My battery is under warranty and I took it to Ford who has a very expensive tester and battery warranty tests over an hour. Ford tester shows that it is good. Ford's CCA test showed that my 760 CCA battery could deliver over 800 amps. Their other tests were about the same - Ford says my battery is still fine, Konnwei…
