Age of the battery would be my concern. Did the dealer do a load test on the battery? If not, you could be in a world of hurt on the side of the highway with a dead battery on your long trip in August. (I don't trust dealers with the ST1300 model as they don't see many of them).
A load test measures the battery's ability to hold the charge during the cranking/starting of the ST1300. A voltmeter is needed to perform a load test. You can pick up a voltmeter for about $20 at your local auto supply store, hopefully, in Nova Scotia. A voltmeter is also good for testing household batteries.
Steps:
1. Make sure battery is fully charged.
2. Turn on high beams for 30 seconds to eliminate "surface charge" in battery.
3. Put a Voltmeter on battery.
4. Volts should be in the 12.3 volt(V) to 12.6V range.
5. Perform load test A - turn on ignition/headlight but don't start engine. Voltmeter should show at least 11.2V. If reading is less than 10V, replace the battery.
6. Perform load test B - watch voltmeter while starting motorcycle. If volts dip below 10V, during the starting process, replace the battery. (the video below is only a small part of information I've read/watched on the internet)

Also note from MCNews article (http://www.mcnews.com/mcnews/articles/battery.htm) - "A fully charged battery is only 65% as strong at 32? as it was at 80?, and at zero, it drops to only 40% capacity."
