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

I was able to have this ready for pick up at my local sear hometown store after our local kmart had closed down. So i got this as soon as i ordered it the same day free pick up. Thanks sears and shop your way.


This battery charger was affordable. Very easy to use. Small sized and light weight. It got the job done. Alittle bit slower than i wanted but it done exactly what it should. I used this on my car battery my husband left his lights on at work. It charged it back to useing in no time.

Must have for long battery life


I own 2 of these to keep the batteries on my two motorcycles from discharging. If your bike sits un-ridden for more than a week you need a good trickle charger. The LED charge indicator is very useful.

Good little battery charger


These battery chargers are great for leaving on vehicles. Work great. I have several of these. These take a little longer to charge the battery than a big charger, if the battery is very low, but a slow charge is better for the battery anyway. I would highly recommend this charger, especially if you have a vehicle that isn't driven all that much.
