I would keep a very close eye on that battery charger because of the dried cells. Cells with levels below the top of the plates will accelerate the death of the battery for sure, but it does not mean they go bad right away. Depending on how dry the batteries were, they might loose their charge quickly, etc.

Don't get me wrong, I'm not trying to question your knowledge or anything, but with electrical systems you have to start with the very, very, very basics.......first of all, with the shore power connected, do you have voltage on your AC/DC or whatever system you have? If so, then is the charger on?...just because you have shore power on, it does not mean that the charger is on. Typically it will have it's own circuit that you need to "turn-on", in order for it to work.

Second, if it is on, what voltage it's putting out to the batteries? Depending on the type of battery that you have, the charging voltage level will be different.

If you have proper voltage, let them charge, until you reach "float voltage" point. Most chargers now a days will tell you when they reach that point.

You might have something else going on, since a new battery, even if it has been on a rack for some time, should start your engine. Doesn't mean that it will always, but generaly speaking, it should. First make sure that your charging system is working.
