Whew! I thought you were disagreeing with Klaus for a second there, Bill.
Terry, that is some small battery you have there, mine is 14 Ah @ 6V. Anyway, if you have a good dynamo and regulator (like a DVR-2), unless you have an electric starter, or plan to read by your headlight at the campsite, or plan on laying on your horn for an hour or so, extra ampere-hours probably don't mean much.
