Click click crank

[MKR]

I think I just drained the battery by starting too much and using too much power, but it can't hurt to ask.

1. Drove to get a haircut
2. Drove 500 feet to Wal-Mart
3. Drove 2 miles to the grocery store

I also had the fan and AC running at full blast the whole time. It clicked once when I turned the key at the last stop, then clicked again on the second turn. It cranked on the third try.

This was after it sat for 2 days. Is this a symptom of putting too much on the battery without giving it time to charge up?
