A 2005 Corolla twice fell to around 8.5 volts after sitting. The replacement battery and a roughly 14-volt charging reading had not prevented recurrence.
What the report actually shows
The owner noticed the radio could remain on with the ignition off and measured different draw values on separate attempts. The radio was a clue, not a proven cause.
Reported outcome
The question did not document a verified repair.
What to take from this case
Observe the current only after modules settle, then isolate the circuit during an actual high-draw period. A new battery does not rule out an intermittent electrical load.
