First time charging new batteries
I just bought a pair of Costco/Interstate 6 volt batteries. On the first two charges, they don't seem to be accepting charge as fast as I expected. They have not gone above 31 amps either time. I a...

Keep charging them 'til current drops to about 1% of Capacity. You're very near full, now, but that last few percentages can take a long time. Make sure the voltage is holding steady... if it is rising continually, current will be held higher, as well.
Then do as others here have suggested, and EQ them. See how that goes.
Again, keep an eye on the amount of gassing. Check SG throughout EQ'ing, and stop once readings stop rising. There will be some lag, so expect to see slightly higher readings the next day or so. If they do not equalize out after one or two attempts at EQ'ing, return them. Some folks say a difference of 30 points is acceptable, while others prefer to EQ at a difference of 10-15 points. I lean to the latter.
