Interesting comments BFL13 and pnichols. Though I highly doubt it, I cannot prove that my charging method did not contribute to my two pairs of 12V lead acid battery troubles. Does innocent until proven guilty apply here? Ha ha.
One thing we seem to agree on.........AGMs are worth the extra expense, whether two-12V/parallel or two-6V/series. They seem to take abuse much better.
Are you sure you belong on the internet? Far too polite! :)
AGMs are good until they aren't, same as other batteries.
Big thing is to have an ammeter (I use my Trimetric) to know they are down to 0.5 amps per 100AH at 14.4 volts before dropping them to spec Float voltage on a recharge to "full".
If your charger won't hold 14.4 that long, like most converters won't, then you will pay the price eventually, and if you don't have a DC ammeter either, you will not be able to tell they are full, so likely leave them undercharged and sulphating.
It's only money, and you will have to get new batteries every so often anyway, so it is just about when, really.
