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.
Works as advertised keeping my classic fully changed and ready to fire. Sleek shape fits well under hood even shut.
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
