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.

Would not buy.. Overcharges.. Sears /Schumacher 2 amp charger

Charger over chargers and runs over 17 volts and will destroy batteries. Does not continually monitor voltage, only every 12 hrs etc California rule BS. Schumacher no longer makes a good Charger, I would opt for other chargers.

Dependable and Long Lasting


The last one I had lasted about 15 years. Considering it was used most of the time, I was satisfied to stick with the same product as a replacement

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.
