Will leaving my hood open for an extended period of time, like a week or so, cause a draw on my battery?? 09 S5 V8

Why even chance it, buying a Battery Tender (what, $79) is way cheaper than a new battery and it'll monitor the battery and only send it a charge if it needs to. Plus you can lock it in the trunk if needed while it's tending your battery.
