Works well... manual isn't great.

It seems to work well for me. The manual could use some improvement, though. I had a severely discharged 12V battery. When I connected it at the 2A/12V setting, the amber Charging light came on... but after 3-5 minutes, it would switch to flashing and stop sending charge to the battery. A flashing Charging light is not explained in the manual. I thought that the battery or the charger were shot (even though both have barely been used). Here's a tip, though... I unplugged it, switched to the 4A/6V setting and plugged it back in... and the Charging light stayed on. So, I let it charge all day long. When I checked later that day, the battery's voltage had gone from 5.8V to 12.4V. I unplugged the charger, switched to 2A/12V and let it charge for another two hours before the green Charged light came on.

I have bought about 4 of these in the past 2 years and each one has never lasted more than a few months. The first two I dropped from a height of about 3 feet. They are my fault (even though they should be able to take some abuse) but the other two the condition lights stop working and it freezes on the green fully charged light or no lights at all. I hooked one up the other week to my Harley. It showed a green light. Left it plugged in. Went to start the bike after two weeks. The green light was still on. Guess what?....Dead flippin battery. I also have a battery cutout switch so it wasn't anything on the bike. These things are junk.......I buy alot of Chraftsman stuff but these are terrible.........thanks

Works as good if not better than most inexpensive chargers, like the 12 to 6 auto option. I have multi units all on different cars and no issues

Never received the item..


I wish I could, I ordered this item about 8 months ago. It was going to be shipped to my home, instead it was shipped to the store. When I went to the store, their wad no record of my purchase. Uhhm, then how am I writing this review on the item that I never received? Even though I offered to pick up the item myself the over the phone service rep refused to allow me to pick up item from another sears. Customer support has really gone down hill at Sears, and now craftsman tools area made in China!!
Sears really needs to re- evaluate their service practices, we have been loyal customers for many decades and do not deserve to be treated this way.
This however might be an excellent device, but I will never know.
Thanks for nothing sears customer service.
