Get a Hydrometer (about $10 at the auto parts store), and check both batteries. It sounds like you have a bad cell (perhaps more than one), that is pulling them down. If so it will take a charge but once a load is applied the batteries will quickly discharge.
What you should see is that all of the cells have approximately the same reading (specific gravity). As long as they all read about the same level you are fine. If one cell reads significantly lower than the others it is bad and there is nothing you can do but replace the battery. One bad cell can easily pull down both batteries if they are wired together.
