Nice little charger.

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.

Chager did not show bad battery.

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.

False Advertising!!!


Purchased this item based on the video that was presented that showed wifi capablility and an app for your cell phone to turn the charger on/off as well as monitor the progress. Once I received it, it was a plain jane model. Called Sears and they offered me 5% off the "Smart" charger and then after I didn't bite, said they could do 10% off. I understand it was a mistake by having the video posted on the wrong product, but I wasted gas and time going to pick this up in the store! Thanks a lot Sears. I'll just return this one and pick up the "Smart" charger during your "Going out of Business" Sale!
