Battery Chargers

Does anybody make a "dumb" battery charger any more? I have a NAPA "smart" charger and it's driving me nuts with all the safety features. Any alternatives?
I've had many of the Schumacher smart chargers, and they work pretty good....for awhile. They just aren't durable at all. I've had at least 3 fail on me. I think they're made with Chinese parts which won't stand up to frequent use.
Try this. I've heard good things. Kinda expensive.
