Hybrid Battery module failures

Well... A charge and balance of pack after replacing modules can make a big difference... But each rebuild of modules replaced DIY style lasts a shorter period of time and it seems like time for you to move on.

The advantage with GreenBean and similar companies is they handle the install/swap and warranty stuff can sometime be to your advantage. Another option is Professor Joe sells rebuilt packs from Gen 4 Prius (2016-2022) and those are as close to brand new as you can get for OEM because brand new OEM prices have nearlly doubled: Prius | 2nd Life Battery

Also check the link in my signature about Sodium-Ion, which I think is your best option.

 

If you plan to continue driving this car, think carefully about the amounts and reasonable investments in repairs.
There may be a small investment associated with the purchase of one or two pairs of modules for a year. Then the problems with the battery will return. The new and old modules cannot work the same. Put an old nag and a young frisky horse in the same harness, make them run fast and soon one of them will die.
Evaluate more expensive methods yourself.

Food for thought.
The original high-voltage Toyota battery has a warranty for 8-10 years, for a mileage of up to 150,000 miles. And it works for the entire warranty period and much more.
The cost from the manufacturer Toyota of a new battery kit consisting of 28 modules for replacement, which will allow you to drive at least another 150,000 miles, can cost from $ 3,000 to $ 4,000.
You can save some of this money or even half of the cost of a new original battery if you buy reconditioned batteries from a private company or non-standard "ersatz-replacement" batteries with different battery chemistry, but no one will give you a guarantee that in a year or two, after ten to twenty thousand miles, you will not have another problem with repairing such a battery. An extended warranty will cost even more than original batteries. Additional expenses may be required for replacement, delivery, testing and adjustment of non-OEM batteries. You can also be denied warranty under any far-fetched pretext. There are several topics on the Prius chat website where hybrid owners deceived in their hopes later faced a refusal to replace batteries and returned to the decision to buy and install a new original set.

The choice is always yours.

My Gen2 has original batteries installed from the factory, in a short period they will be 20 years old. And when they fail, I will replace them with original Toyota batteries of recent years of production.

 

The other option is to get a couple packs on the cheap that need work because you already know to rebuild them and then you'll have a backup pack on your shelf ready to swap out with a rebuilt pack in your car at the first sign of trouble. Of course that's time consuming unless you enjoy that type of work...

 

2007 battery with almost 200k miles is most likely dead, dried out. The modules will fail one by one until eventually all 28 modules are replaced.
I would buy a used Corolla battery from a junk yard and restore the capacity using the Hybrid automotive method before using the modules.
