P0A80: Replace Hybrid Battery Pack
This is the definitive diagnostic code indicating hybrid battery failure. It triggers when your vehicle's computer detects that the voltage variation between individual battery blocks has exceeded the acceptable threshold (typically 1.2V).
Why did I get this code?
- Cell imbalance: One or more cells have degraded faster than others.
- Phoenix Heat: The harsh Arizona summer accelerates chemical breakdown, causing premature resistance buildup.
- High Mileage: Natural wear and tear after 100k+ miles.

While a dealership might automatically quote you upwards of $3,500 to $5,000 for a completely new OEM battery, our mobile replacement options start at just $800 with a warranty.

Why is my hybrid fan running so loud?
If you hear what sounds like a vacuum cleaner coming from the backseat or cargo area of your Prius or Camry, that is the hybrid battery cooling fan working overtime.
When the battery begins to fail, its internal resistance increases. This resistance generates excess heat. To prevent a catastrophic thermal event, the vehicle's computer commands the cooling fan to run at its highest speed continuously. If your fan is constantly loud, battery failure is likely imminent.
