+1 on trying to save them. Fully charge, then have a proper load test or conductance test done and see how they do.
If you have an ammeter, you can set up a test with your MH by turning on enough "loads" to do a reserve test. Example: you have a combined amp-hour capacity of 400. You turn on enough loads to draw 20 amps. (5% of total amp hours) After 10 hours, you should be down to 50% of battery capacity (if all are good) or 12.0 volts approx.
