Led readout is easy to read and tells when the battery is charged and on auto maintaining the battery charge. I use it for my lawn tractor battery and it works very well.
I was looking for a charger to keep my car battery charged though the winter. I came across this one and watched the video and thought it would be a nice one. Looked at the reviews and most of the reviews were good. So I thought I would give it a try. Once I got it and read through the manual I found out that the video is for a different charger. Diehard got me. I will take the reasonability that I did not read all info for the charger, but the video they have for this charger is very miss leading as it is for the higher end charger. So that is one of the reasons why I give it a 2. The other reason is that it says that it will tell you if your battery is bad. The unit that I got does not. My vehicle was dead it would not even unlock the doors. I Pulled out the battery and hooked it up the charger said everything was good and started changing two hours later the unit said that the battery was fully charged. I put it back in and nothing the car was still dead. Got new battery and my car started up just fine.
Love this item. I use it to charge a battery that I use to power a slow cooker to keep chili warm for football tailgates. It works perfectly.
I already had the 6 amp, larger version of this unit & was very happy with it. I purchased two of these smaller 3 amp units & am just as pleased with them. When you first attach this charger to a battery it analyzes the state of charge of the battery in a % reading. It will also automatically go into a desulfation mode, if needed, to attempt to restore a bad battery. The box also contains a cord to permanently attach to a battery for a quick connect and a 12V plug to charge your car battery from the passenger compartment of a vehicle. Keep in mind though, at 3 amps it is primarily a maintainer charger but will charge large dead batteries if you are willing to wait.
Purchased this product on June 4, 2017 and the display only worked for a very short couple of days. This was in fact a waist of my money
Great little charger. 3 Amps is not much, but it has many nice features to offset that. You may want a bigger charger as well as this one.
The only problem I've had with mine, almost 2 years old now, is that when your 12V battery gets almost fully discharged, near 0V, and you try to charge it with this ... the charger thinks it is a 6V battery and takes it to 6V and that's it. There is no way to override this, it is too smart (but not really).
Great as a maintainer, analyzer, conditioner.
Good for slowly (the best, patient way to do it) bringing a slightly depleted battery back to full charge.
Fails when trying to bring a 12V battery back from full discharge.
So very good product. 4 stars. I bought an extra one and gave it to my parents.
It says slow charger and means slow charger 3hrs from dead and not even a light works. Also, it can't read the difference between a 6v and 12v. It said fully charged at 6v but cars are typically 12v so of course it doesn't turn on. Piece of junk and waste of money!!!
It detects 6v or 12v ... it analyzes the battery (including, detecting if the battery is bad) begins charging and displays the percent of charge. When battery is fully charged it goes into maintain mode and will not engage until it detects the battery needs a charge. Small portable and easy to use!
Got as a present used it on my old truck worked great
