New HV Battery to be installed in my Taycan -- will it be a new or rebuilt battery?

[Briguy]

A question for guidance please. PAG has advised my dealer that it will replace my ‘20 Taycan 4s’ HV Battery. It suffered the red circle of death (late November) and has been sitting at my dealer ever since. Late december PAG advises of the plan.

Should i be expecting a truly “new” 93 kvw battery or a rebuilt version? Is PAG even producing still the 93 kvw battery anymore?

BTW, still no ETA on the arrival of the replacement battery.

You will get a rebuilt version that will be Part Numbered that way. I would capture that and share with us if you could. I am going by the most recent experience of the battery replacement by @Maelstrom and we measured the battery SoH together and it clocked at brand new 99%+.

Does it matter if it comes with a new 8 year warranty?

Will it come with an 8yr warranty though?

If it does, win win. But I'm not sure that's how these things roll.

I think you are correct.

Most warranty replacements will come with the warranty to match the original time frame. The fact that one has a completely new part is of course a lot of comfort.

It maintains the old 8 year warranty it doesn’t start over.

Thanks for that. Given the issues PAG seems to be encountering on the first gen battery packs, it left me wondering what their strategy would be in this situation.

While I dont understand the tech to know what is flawed in their original battery packs design, it appears to generally be good enough (absent a more unique “one off” defect) to last 3-4 years of strong performance.

A more cynical approach might be to say they will replace it with whatever is required to get the car to the end of the 8 year warranty period.

I'd certainly ask the question and push for it if not given the inconvenience etc.

There will be stocks of J1.1 batteries (replacement parts etc) held by Porsche / LG / whomever manufactured in the first place just like any other component.

I don't disagree that it would be the fair thing to do. It's just ever how it works.

Would be even nicer if they figured out a path to using the J1.2 battery in a J1.1 and gave that as an option....longer term it would make sense for them IMO. But customer satisfaction doesn't seem high up the agenda!

Porsche missed a trick here and should have road mapped the inevitable switch in battery chemistry (it didn't happen overnight) and offered this as an upgrade path.

The underlying issue (my guess) is that the architecture of J1.1 and J1.2 is different - both are 800v BUT the J1.2 has 2 x 400v rails effectively splitting the battery when it comes to charging - but implementation of the booster a little different hence faster and negates the nonsense of the additional DC booster (400v to 800v) we added to our J1.1s to ensure we got 150kW from 400v EVSEs. So the battery type is one thing but the plumbing another.

My HV battery failed last year in my 2020 4 S with the larger battery. I noticed a loss of range in a short time period and brought it to the dealer. While troubleshooting was underway the battery failed. After about a month my car received a 2023 remanufactured HV battery with the part number 9J1-915-100-EX. No additional warranty, it continues with the 8 year warranty from purchase of the car.

that’s a good result. Fresh new battery is a win ?

Remanufactured is not fresh new, it’s the broken battery of some other bloke, that got fixed and now they put it in your car. And the bloke from which you get the battery got the same, from some other bloke.

For anyone interested in this red circle of death/battery replacement story...an update.

Porsche shipped from Europe to my Toronto, Canada Porsche dealer a brand new 93kwh battery to be installed in my '20 Taycan 4s. It has now been installed and the car is going through some final programming/checks before being returned to me.

I got a brief education from the service tech dealing with my car about battery issues. Apparently PAG is now (or has been for a while) approaching battery issues in gen 1 Taycans on the basis of model year. I was told that MY2020 (first version of the car) will get a brand new battery if the original battery has issues. For MY2021-2024, battery issues are solved by replacing individual battery cells which have problems. I understand that PAG evolved battery design after MY2020 for the later generation 1 Taycans.

That said, now that I have a new battery pack, any future issues would be resolved at the individual cell level.

The tech explained that it is an arduous process to deal with battery cells and requires the disruption of the sealed battery by removing rivets and sealant with created a fully protected environment. Resealing it requires new larger rivets and a sealing process that must be completed within a short time frame to be effective. He said the process requires a minimum of 35 hours of tech time. Ouch if not under warranty.

From the resale market perspective (and not sure that the tech was right), he said that original MY2020 Taycans were somewhat more desirable because of the eligibility for a full battery replacement.

Sorry for the run-on story. I found it really interesting. My layperson's sense, with zero engineering knowledge, the cumbersome battery design makes servicing a huge and costly challenge.
