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.

Misleading Charger/Maintainer

I've read other people's problems with this charger and Sears doesn't want to stand behind it. They keep saying it's the customers lack of knowlege on what they are using it for. When it's being used first it works fine then the charging light will start to blink/flash which it is NOT supposed to do!! Then once in a while if it does actually work right it will not kick back onto charge if the voltage goes down by running something off of the battery that it is hooked up to. Overall DON'T BUY THIS BRAND OR MODEL!!!

Served its purpose

|

Did absolutely what it stated it would do and worked pretty good I want to say it worked better than a friends that had a better looking model and brand but this one was cheaper and worked just as good if not better in my opinion. Only thing that was a little annoying was the terminal clamps were really small could have been just a tad bigger and had more of a handle to them for better gripping and attachment but worked fine just the same.

Excellent Product! Typical Craftsman Quality.

|

I first had doubts about this unit given its small, light weight size, but it restored a completely drained car battery in about 24 hours. It shut off when the battery was completely charged. Easy to hook up, with common sense (!) although the manual could be a bit clearer. Very happy with this trickle charger.
