Leaf Battery Issue
Hi all,
Back in February, my 30kwh cut off under hard acceleration. The temperature outside was cold and I was accelerating and driving hard. As I was driving, the range was dropping at some points, 4% at a time.
ChatGPT felt it would be the 12V battery. I went to a local store and they said the 12V was fine. You guys felt it was the main traction battery with very weak cells and to use LeafSpy.
I’ve conducted some tests and uploaded some recordings to YouTube. I’m not an expert, but apparently my readings are OK for a car of its age, mileage, SOH and there is also quick rebound to more sensible numbers. The 12V seems to spend a lot of time at the low 13V or under 13V which ChatGPT says could be an issue. if you’re more of an expert on this, would you mind skimming through these videos to see if I have anything to worry about?
40mph to 70mph, accelerating hard (foot to floor):

Motorway - maintaining 70mph, pushing to 78mph maintaining at 75mph.

Up Fairly Steep Hill - Flooring It (No Eco) - 20mph swiftly up to 60mph - SAME HILL THE CAR BROKE DOWN ON. GOT SOC LOW TO TEST:

I know the likely culprit is the traction battery. This was back in February but the car has been okay since. I have driven it “nicer”. I’m hoping to keep this car for a couple more years. Is the problem likely to accelerate (pardon the pun!).
