Prolong for this battery pack, or just wait to replace?

I have a new to me 2010 with 200k, this is my first hybrid. I bought the car prepared to do a traction battery if needed, but have been driving it daily for over 2 weeks with no drivability issues seen. The car shows P0A80 stored. As far as I know this is the original battery.

Would you invest $700+ in a Prolong system for this pack, or just wait it out and drop the $1,600 for a new pack when the day comes? With the Prolong at nearly half the cost of a new battery I'm questioning if it's worth installing.

Any other suggestions besides these? Another charger I haven't seen? Something else to keep the car going?

I'm not up to speed on these batteries yet, but I've attached some screen shots from some testing if any of you would mind taking a look.

 

I'm the DIY type.
No prior hybrids.
I believe so, $2500.

The car seems solid and drives well, it performs as well as I'd expect, good acceleration, no quick SOC changes, can go well on just battery, holds charge overnight... I've nothing Prius wise to compare to though other than a few short gen 2 test drives as I was shopping. Much preferred the gen 3, though this is the only one I've driven.

If I'm reading those basic scans right the battery doesn't seem in imminent danger of failing, but I was hoping some of you who know them better could verify how things look. What's throwing me off the most is that the car holding the code, P0A80, no cel or triangle. Just from driving I wouldn't suspect an issue.

The one thing I've noticed off about it is the dash clock resets overnight. No radio resets, just the clock. The 12v was 12.8 with the car off and 14.5 in ready.

In case there's something else I should pull up, I currently have Dr Prius, Carrista and Bluedriver available, and just downloaded Hybrid Assistant but haven't played with it yet.

 

I assume techstream will get me further than the elm stuff I have, especially with reading deeper codes, but how much more detailed is it than the attachments above for reading battery condition?

What I have now shows the block voltages, resistance, etc. My limited understanding seems to be everything looks to be in line, high and low voltage difference in the .1x range, resistance close. Is there anything in the screenshots that I should be worried about?

 

Thanks, I'll add these to the to do. I'm also planning to change all the fluids.

So far I've driven about a thousand miles with no noticeable oil consumption, hopefully it holds, seller said he had just changed it. Are folks doing the catch can when no oil is burning, or only once it starts?

 

Fair advise.

I've seen them as low as $1600 from some dealers, much higher from others, just depends where you are. When I checked with my local dealer they were willing to work on the price, we'll see when the time comes.

I've also been leaning towards the new design from newpriusbatteries for $1600, it seems he has a good reputation here, though I don't think he's been going very long. He doesn't give much warranty either at 2 year/25k, that's about my annual mileage, to be fair OEM warranty sucks too, but is proven. Anyone know how long his packs have been out in the wild? Any known failures?

 

Ah, gotcha. Looks like it's still $2100+ for the gen 3. Hopefully it comes down before I need one.

 

That's my concern. I'd find it valuable for maintenance and reconditioning, but don't expect it would compare to a new pack.

I know there are lots of rebuild threads here, but don't know that I've seen anything specific to how well a Prolong build will last compared to someone balancing with hobby chargers. My understanding is that most rebuilders are playing wack-a-mole pretty often, and I'm sure the Prolong makes that easier, but does it make it less often? Do these rebuilds last longer?
