You are reading page 11 under initial charge current limit. Go to page 6 in the chart at the bottom which lists "Maximum Permissable Current(Amps)"
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.

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.
