After reading many reviews about on-board battery chargers I've found one
common thread - they all fail relatively quickly. I'm not certain if only
those that have problems post their reviews or if the darn things really
fail at such a high rate. What's the best you can expect out of a charger
and who makes the most robust ones? I'm looking for a 15 amp three bank
charger - I usually have the time to charge my batteries overnight so I
don't need to pump 100 amps/hour in to them.

The only thing that I've found in a commonality is that they're a great
invention. Some are better than others, but they're all better than
charging batteries via a battery charger. I had great luck with mine in my
last boat, I believe it was made by Dual Pro. Four years and never a
problem. As far as I know, it's still going strong.

The onboard system I have now is made by Stealth. The neat thing about this
system is that all three type 31 batteries are charged either via AC power
or by the outboard when the motor is running.

36 volt trolling motor hard all day and it's back up to peak charge in mere
hours after I get home.
