2023 Acura Integra — battery dies after the car sits for a weekend

QuietCollector76Community StarterMar 15, 20262023 Acura Integra A-SpecBrooklyn
Battery passes a quick test and charging voltage looks normal, but after two or three days parked the car sometimes will not crank. What is the cleanest parasitic-draw test on a modern car that takes time to go to sleep?

Ask what changed right before it started. Loaded-suspension checks on the 2023 Acura Integra catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Did the worksheet show tax yet? Happens in gear, not in park, for what that's worth.

OP update: scanned the 2023 Acura Integra again and still only have the one pending code, no new lights. I'm keeping receipts and dates in one folder.

I wouldn't throw parts yet. A pressure test beats staring at a dry driveway if the 2023 Acura Integra is losing coolant with no puddle. If the cheap test changes it, stop and reassess. Time, temperature, and whether it's in gear are the notes that actually help a shop. If the story changes I'll post the new data.

Checked the easy stuff on the 2023 Acura Integra and found one clue worth chasing before I book a shop. Happens in gear, not in park, for what that's worth.

This is usually cheaper to test than to guess. A pressure test beats staring at a dry driveway if the 2023 Acura Integra is losing coolant with no puddle. Save the big job until that test fails. I'd want that in writing, not as a promise. Checking again after work.
