prius c P0A80 replace battery pack ~ 2wks after parked rear end

That code indicates a balance issue among the modules in the pack. That indicates a failed pack, not a drained one.

 

it's fine to drive. i would pull the pack and have a look around. 6 years is a bit unusual.

how many miles on her?

 

Balance issues can often be caused by one cell self-discharging faster than other cells... Or if a cell is weaker than others as high amp loads charge and discharge is what throws the warning lights. The former can be fixed w/charge & balance of pack and the latter is fixed by simple reconditioning or replacement.

HybridAutomotive.com has a system that makes charging and balancing easy, as well as reconditioning. Or alternatively you can try force charging the pack: put car in drive, foot on brake floor the gas pedal.

If you lived near me, I'd simply put in a loaner pack and recondition and replace bad cells in your pack and you'd be back on the road for up to a few years and cost would be less than $500...

But if you buy brand new pack then pack is good for a decade....

 

If you’re lucky the major issue may be bus bar corrosion. Cleaning or replacing and retorquing the nuts may help buy some time.

 

Sometimes you can reset the computer to make it forget that it detected the failing battery pack, and then keep driving. And some people can get away with quite a lot of normal driving after doing this- but not everybody. It really could fail the same way again, and it is really, really hard to make predictions about it.

Has the car been parked much lately? These hybrids (their batteries really) appreciate daily use. Doesn't have to be a lot, but they need frequent exercise to stay in good shape. Sitting is bad.

Also, check your battery cooling fan. If the fan or ductwork is blocked, the battery can show failure symptoms prematurely, and if the poor ventilation isn't fixed the battery can be damaged permanently.

 

Anything is possible but no. Just like a flashlight with a dim yellow light is (almost certainly) due to nearly dead batteries not because someone dropped it last week and put it back on the shelf.

 

Once the pack is charged up the computers will stop you from charging it further... But it's best to use Dr. Prius app to better monitor the details of it all as it happens so you know how each of your 10 blocks of 12 cells each is responding to that kind of relatively high amp charge. Here's buyer's guide for device you need to make app work: Hybrid battery diagnostic and repair tool for Toyota and Lexus

 

What are the error codes and sub codes you're getting via Dr. Prius app? You can monitor and clear codes as they pop up on your 100 mile trip and things will likely succeed without incident. But if you don't know what the codes are pointing to than you're flying blind and may end up broke down on side of the road. Let us know the codes and we'll be able to explain what your chances are for your trip?

 

yeah that code is just saying there's a problem with the pack, but you have to access the subcodes to know the specifics of the problem.

 

Dr. Prius is good enough in most cases...
