I left my Si in my parent's garage for 9 days while I was relaxing in Mexico, and when I got there to pick it up the battery was dead. Is that typical performance for the stock battery in these cars? If so, how long can it sit without needing a charge? It seemed like it was on the cusp cuz it tried to start but died after a several groggy cranks.

If storing the car for more than a month Honda recommends disconnecting the battery. If yours went dead in 9 days something is not right or you left something turned on.

I'd take it to the dealer for a check, a faulty battery should be covered by warranty.
