Need new battery - keep getting low warning
This battery thing is confusing me. It's been throwing the low warning for a while now once I shut the car off. I was wondering why my angel eyes weren't turning on when I approached and unlocked the car but I just learned that's what the battery does, shut down some things since it's low. I just had a misfire and was wondering if this was part of it as well so looking to get a new battery.
What are the specs of the aftermarket batteries you guys have bought? I have no clue what these mean AGM XX AH blah blah. What do i need to buy? haha any links?

I can't recall the exact part number, but look at the top of your existing battery and get the specs off of it. Advance auto parts carries a direct replacement (they had them in stock at my local store), it was around $200 or so I believe, and they'll give you a credit for your core trade-in.

Depending on the brand of choice or availability, you can search manufacturers.

Below thread has some info, I believe I went with the duralast platinum H8-AGM when I did mine. You can save some dough at autozone.
