Even after reading a bunch of posts, I can’t figure out what’s draining my battery. I replaced the original battery after 3.5 years, and even with the new one, I’ve needed jump starts after not driving for a week. Now, it’s down to every 2-3 days. Auto daytime lights are off, and my remote key is more than 10 feet away. Any ideas?
Could it be the alternator not charging the battery right? You should check the voltages while running, both with and without a load. Also, check for parasitic drains—sometimes it’s something like a bad ground or hitch wiring.

I’ll have someone check the voltages. It has a dealer-installed remote starter, but I rarely use it. Could that be causing the drain?

Could be! If the remote start is protected by a fuse, maybe try removing it to see if that fixes the issue.
I feel you on this… electrical issues are the worst. I had a bad ground on my Maxima years ago, and nobody could find it. Turned out to be the ground cable after replacing the battery and alternator!
@Clove
Yeah, I had a similar issue with an old car. Took forever to figure out it was the ground! Hopefully, this one isn’t that bad, lol.
Is the dashcam in parking mode? That can drain the battery without you realizing it.

Nope, no dashcam. I’m trying to keep it simple, but something’s still pulling power.
Maybe there’s a hidden light staying on, like the visor or glove box light. Those can be sneaky battery drainers.

That’s a good thought, I’ll check for any lights staying on. I didn’t even think about that.
