You probably would be okay if you had taken the day off and spent 8 or so hours riding instead. Simply put, 45 minutes riding isn't enough to charge it from flat. How old is the battery? Depending on that, you could probably get away with buying a battery charger and leave it on over night. But then no matter what, you'll have that niggling wonder in your head of whether it's going to die on you in the middle of nowhere sometime soon.
Me, I would charge it with my charger, and use it.
Oh, by the way, there will likely be a lot of opinions on this. This is just mine. The same thing happened to me about 4 years ago. I'm still using that battery.
Ride every day, it's good for you.
