Sounds like this one:

I have used this model for eight years and have never had a battery failure.
I've had quite a few battery chargers and this one is the best (in my opinion). They ain't cheap, but good stuff never is unless you buy Flipmeister stuff.
Here is the one I have http://www.battery-rechargeable-charger.com/auto-vector-car-battery-charger-products.html
I have the model VEC 1093A. It gives up to 100 amps but for little batteries it idles down to 2 amps or less. It's a helluva charger for 120 bucks. I did have to replace the alligator clips. I inadvertently ran over them with the car. It has internal cooling fans and it's well made.
Cabela's has them too http://www.cabelas.com/prod-1/0037994018462a.shtml
I never buy anything at Cabelas. We have a big store about 5 miles from here and so I get socked sales tax. I'd rather buy elsewhere like LL Bean.
