2010 Prius Hybrid Battery P0A80 pinpointing which cells need replaced Techstream diagnostic included

What you're doing is considered a "whack a mole" type of repair. It most likely will not last long and you will have to do this over and over again.

I think your car is still fairly low mileage and with the car prices being so inflated now, it would be a good idea to keep this car running reliably for a longer period of time. The best solution to your problem is to put in a brand new battery for $1600+ and then you'll have trouble free (in terms of battery) for 8+ additional years. And when it's time for you to sell the car, the new battery will add significant value to your car. So it's something that will pay for itself eventually

 

whack a mole type of repair will not guarantee anything. If you want it to last 15k miles (remember the modules are older than when you first repaired them), you'll need to properly recondition and balance ALL of the modules. That way you'll have a longer lasting repair, possibly giving you 15k miles of trouble free driving

 

These words above are most often said by wealthy people with zero experience in rebuilding hybrid packs because they don't think twice about spending $2500 on a something that only costs a pack rebuilder $30 per bad module.

Many people get lucky and get a year or more when they replace the first bad module or two. And the more you learn how to properly test and recondition modules, the easier it is to offer a 3 year warranty with a rebuilt pack. It's such a relief when the warranty expires on your pack and it never came back!

 

I don't know how any rebuilder can comfortably offer a 3 year warranty on a rebuilt pack. Of course if you charge enough money for a rebuilt pack, it wouldn't be so bad to service a pack a few times during it's warranty period.

I've rebuilt many packs and have the equipment to do so. But all my cars have newer batteries in them. Call me lazy, but I like easy and trouble free driving.

 

Whack a mole problems can show after a few hours or a month. After a month, it should be good until the next module fails

 

Going on 2 months now and no update......sounds like the OP hasn't had to use that mallet! Nice!

 

Replaced a few cell recently and used car scanner for diagnostics, this tell you which cell has brought on the check hybrid system light, change both cells on the failed block and you should be good to go.
