Picked mine up last Friday after 5 weeks to replace a faulty cell as SammyD suggested.
Great to hear it’s back to full health - but 5 weeks to replace the cell?!? Mine’s only just been in 1 week but they’ve said it’s looking very likely there are faulty cells (plural). Let’s hope they’re getting faster as they do more of these. Can’t wait to have 200+ miles of range again.

Hoping yours is quicker. Yours will be the third replacement at the centre and they originally fitted the pack to mine incorrectly. That apparently meant a further 26 hours strip down and refit, adding a week. It also took a week to two for the parts to arrive.

You’ll enjoy those extra miles when it’s back- no more 5 year old i3 range! Also the GOM can be relied upon in normal driving.

FINAL UPDATE:
It’s fixed. After 7 weeks - a new cell installed and a repair to seal the battery ‘frame’. Here’s the detail:-

One of the tests conducted was battery pressure. It was found that there was a 0.6-0.7 bar pressure drop in the battery pack. Two small leaks were identified, towards the front, one each side. A repair kit was sent and it was sealed. The limit for acceptable pressure loss is 0.5 bar the tech said.

Next a cell test was conducted and one of the (32?) cells was found to have 11.9v compared to the others at 12.3v. JLR confirmed the data and approved a replacement. That’s what added several weeks to the work.

Thank goodness for the warranty. JLR were excellent, the dealership kept in communication and ultimately did what you need from a dealership. I have my car back. And I’m looking forward to care-free journeys of 200miles+ and no longer having to keep a spreadsheet of every charge and every journey!

Name the good dealership - we shouldn't just shame them. ;)

Harwoods Croydon, UK.
I was only their third battery customer, I believe.
And I also followed others’ advice to contact Jaguar directly and discuss the situation with them, which I feel helped to ensure the dealership was ready with the right tools and helped me understand what steps to expect (ie JLR gives approval for the work, not the dealership). Took a while, but can’t fault the service.

So you literally see 80 % right, is not that you see 100 % but that the range is 80% from what it used to be? I would at least remove all in car scheduler settings, sometimes this also messes up a shcedule...

Hello everyone

Hijacking this thread to ask those with more experience in battery health.

I'm looking to buy a used I-pace and are asking for a battery state of health report.

The first one I got said the health was at 81.5% (which is not normal for a car with only 4.500kms and a little over a year old).

However, the screenshot was from the main screen (not individual cells) and said "test in progress". So I asked for a re-test and individual cell report. The one I got then showed the individual cells alright, but not the state of health, instead it showed the voltage.

All cells were at 10.7 and one at 10.8. But don't know if that's immediately translatable to state of health or not.

I asked for a third test (individual state of health), but don't know if I'll get it.

What do you think? Probably a battery problem?

So they agreed to conduct a 3rd test (see my previous message) and I told them to charge the car first (I don't think they had, the previous times) and leave it plugged-in during the weekend in order for it to work its balancing "magic".

I'm sure the result will improve (since the car had been left unplugged and unused for who knows how long, surely months) but don't know by how much.

Normally they'd have to go through a few charge/discharge cycles and then test, but I don't think they'd bother doing that.
In any case, I'm hoping for the best!

Hi Gonzalez12. Actually, no. All apps, etc, showed car charging fully to 100%. What I subsequently calculated was that the cumulative kWh used was far less than the kWh pumped into the battery. The low mileage achieved was an indication of the problem, but tracking the kWh going in and kWh getting used up, was what proved I had a problem.
