🚗 Keador 12V/5A Automotive Smart Battery Charger: Efficient Trickle Charger for Car, Motorcycle, Boat, RV, and More (Yellow) Review

Product worked as advertised. The ad is good. The fan helps the device charge (not the battery. Just to clarify). I bought it to continuously charge my Allis Chalmers 6140 tractor battery. It needs at least 14.5 volts and a starting current of 1000 amps. This helped me reach a full charge and start my tractor. Many Thanks.

Much better than expected, especially for the price. Used 10 times, works great! I love how once charging has started it shows a simple bar graph in 20% increments of how low the charge level you are at the moment. I'm surprised that with only 8 amps it can handle a 12v deep cycle from 20% to 60% or 80% in just 2 or 3 hours. I reported this to my boss and he kept it and gave me the money I paid for. Now I'll buy another one!

I bought blue and green for 2 of our cars that are not used very often. They are a bit big to leave them in place for the charger. But for occasional charging, they work really well! When using a 12V AGM battery, does the state of charge display seem a bit confusing? I just bought a small 1.5A 12V charger to permanently mount in the engine bay. This should make it easier to use as a battery maintenance tool!

I bought this to simulate a 50w solar panel. I'm excited about this device. and run it. I was skeptical due to the lack of sparks but didn't see any. Trust me, I've tested many functions and this has always been something I've been looking for to make or break connections. If I had to say something bad, I could use my imagination and say that the fan is a bit noisy. I can still hear NPR (radio) set to background levels above the fan. I recommend this device.

I used it to charge and repair my car battery which was no longer able to hold a charge after just a year of use. To be honest, I only drive my car once or twice a week. Actually I wanted to send the battery back because it was still under warranty. I bought this charger/impulse repair to charge my lawn tractor battery because my old charger gave up the ghost. I decided to try it on my car battery in repair mode and charge mode. To my surprise, he completely repaired my car battery and now it…

After looking at many similar battery care products, I chose this product based on price and features. It didn't get many reviews but I thought wth why not try it. I like it! What I didn't notice in the details of the product is that it increased the temperature. Of course it's a C, not an F. That's the only negative I can say right now. But it's better than nothing. Could this affect charging? In any case, after using HF's Float charger which didn't let my plow truck's battery sit in the…

I tested this charger on: 1) gel cell which I know is bad. Does the charger say the failed battery is fully charged? Nothing about the battery, even charging is not accepted. I don't expect this pulse charge to fix the battery, but it says it does. This charger is anything but smart. 2) The gel cell that I know for sure is only good at 8 volts. This charger runs for about 45 seconds and reports that the battery is fully charged. The fact is that when tested with a Fluke voltmeter, it charges…
