Last question...the other battery was a Yuasa 5-series. The battery had a small black hose (1/8th" no more than 3/16ths") that fit into a plastic 90-degree black plastic elbow, which stuck into the battery. Some kind of a drain?
So, was this the original battery? The new battery doesn't have a drain hole. But I am not too concerned about that.
Your Yuasa battery was an old lead-acid battery, the tube was an electrolyte overflow tube. Newer batteries maybe be sealed, gel, glass-matte (sp?), or other technology that doesn't require a vent. The newer ones are better in many respects, most notably, they won't as likely spill acid and cause corrosion around the battery compartment.
The Yuasa may have been the bike's original battery, I've forgotten what was original, but a lead-acid like that certainly may have been the original.
Rebuilding old AirHeads and similar early bikes almost always requires rebuilding of the battery box due to corrosion.
Charging requirements maybe different for some newer battery types so I suggest checking what type of battery you have.
I'm no battery expert, others on this board know much more than I do about 'em.
BTW, congrats on the new bike. I have a 2000 and wouldn't trade it for a newer one. Yours with less than 40k miles is like a new bike.
