You will see "All bolt or recpetacle" lists 6CA which is 6 time the Ah rating of the battery. In our case 17.2 times 6 = 103.2A maximum Amps.

That sure looks like a maximum
discharge current spec to me. The maximum charge current of 0.25CA appears immediately below it, as well as being repeated in the charging section on pages 10-12.

The battery charger should be a smart charger with voltage limiting based upon state of charge. I verified all this information with my battery supplier and was told that you cannot overcharge these batteries unless you charge at too high a voltage. He recommended no more than 30A or so, but for longer battery life 10-20A max would be ideal.

I don't know what your battery supplier thinks he's telling you, but 30A is more than five times the recommended value. "High charging current can cause abnormal internal heating which may damage the battery."
