N.B.: You know when I see your nickname "Dave in Oly" I always think of Olympia Beer -- My given name is David and when I was in the Army I drank gallons of Olympia Beer as it was always 10 cents a glass on draft at the Fort Lewis, WA NCO Club.

Cheers


Awesome!! You are the 3rd famous person I know who like Oly Beer! :)

In Re: The photo -- I used to have a white satin suit just like that which was tailored by the "James S. Lee Hong Kong Tailors" -- this was when I was stationed both in Thailand and in Penang "back in the day" -- it was my "Off-Post Party Suit". LOL Memory Lane. One of those guys looks like a young Elton John, too.

I never got the change to run LeafSpy stats on my 2013 MY (Feb build) but the capacity is very close to the OP (determined by charge time / total kW needed). It also has 8 bars left. 49,000 miles.

So given I still have 3 years left on the "defective" warranty, would the following actions speed up an actual failure of a cell or cells resulting in an entirely new battery?

1. Fast Charge it every day during the summer in 90 F heat.
2. Keep it at 100 pct all the time and leave it for days.
3. Discharge to near 0 pct (before turtle) and leave it for days.

Was disappointed that Nissan refused any assistance request at the 5 yr 3 month mark when the fourth bar dropped. But in day to day use it still has been great for commuting, errands, etc.

The odds of increased battery heat causing a cell failure aren't good. You'd be much more likely to just further degrade ALL of the cells.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

None of that will "force" any single cell to fail but will degrade the entire pack and will invalidate any warranty claims.

The thought of discharging the pack to zero and letting it sit will create a "no car" situation. The rest will simply speed up the degradation process.

Although wouldn't it seem logical a further degraded pack would "finally" cause cell failure? A degraded pack by definition has cells that are unavailable due to some of them dropping below the minimum voltage?

This is actually my "3rd" car so even it became not drivable, I've got 2 other vehicles to depend on anyways.

ALL warranties are limited and slanted HEAVILY in favor of the manufacturer. Abuse simply is their out. You will make it easy for them.
