You can coarsely determine their state of charge by measuring their quiescent voltage -- i.e. their voltage when you haven''t tried charging or discharging them in the last few hours. Lead-acid batteries (and, well, a lot of batteries) become less charge-efficient as they get nearer to top-of-charge. ...

One of the failure modes of Lead-Acid batteries is that one or more cells can develop internal short circuit paths that result in varying amounts of self-discharge current. If your existing battery maintains its voltage above 12.5 Vdc for a week or more while sitting disconnected from anything else, it should be good.
