2025 Toyota Camry XSE — need advice: Battery keeps dying after two or three days parked

TowCommuter12Community StarterMar 23, 20262025 Toyota Camry XSENYC / Long Island

2025 Toyota Camry XSE, about 78,000 miles. Battery tested okay at a parts store, but if the car sits for a weekend it sometimes won't crank. Alternator voltage looks normal while running. How would you narrow down a parasitic draw without pulling every fuse blindly? If I fix it I'll come back and update the thread.

Log the conditions before you spend. Get a real battery/charging test on the 2025 Toyota Camry, not just resting voltage, before blaming a module. That's the branch I'd chase this week. On “need advice: battery keeps dying after two,” that was the fork that mattered for me. Run the total, not the monthly, before you commit. Climate here is different, so treat that as a local data point. Trying not to diagnose from the couch.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2025 Toyota Camry, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. Happy to compare notes if your setup is different. Worth doing even if the car feels fine right now. Wrote this up on my lunch break.
