Associated Equipment makes some of the heaviest duty and Made in the USA chargers on today's market, but you buy once, cry once.
I have their 9425 20amp benchtop model, which is in their Intellimatic series. That series are smart chargers that can also be left attached indefinitely in float mode, after the smart charge sequence has finished. The 9425 also has a dead battery assist.
For the OP's specs,
this model 6010B would be better suited. It is not a smart charger, however, but a manual type.
Link to the 6010B charger on the Associated web site.
