I just turned owning my 2015 to 5 years last week.
Yes, at least once per month when I am low to get home, there is a free QC on a highway "Welcome Center" near work. But I only let the QC charge to about 80% because going higher takes a LONG time...
Same here; car still had the protective plastic sheeting from transport and had to wait for them to prep it. Hit 5 years at the beginning of November and still has all 12 bars. Only about 26000 miles, but still a markedly better battery performance than the 2012 I leased.powersurge wrote: ↑Wed Dec 18, 2019 7:26 amYes, at least once per month when I am low to get home, there is a free QC on a highway "Welcome Center" near work.

I think that I lucked out with the battery because I bought the car as the it was being delivered to the dealer... Right off the truck, and the car spent NO time sitting on a lot for months... It felt great... Like getting fresh bread at the Bakery!
We have a 2015 Ser here at 145,000 miles with 12 bars who violated well over half your suggestions. Might want to consider your climate's contributions to your effort. FYI; since his car is newer than yours, it makes sense that his SOH is higher than yours.arnis wrote: ↑Sun Jul 28, 2019 5:36 amYesterday was the 5th anniversary of my 2014 Leaf. 148500km, 92200mi. Still haven't lost my first bar, SOH ~87%.
Secret sauce - keep it charged at 80% by default. You can charge as soon as you want (if battery is not hot).
Don't be afraid to drain down to 3% on weekly basis.
Don't be afraid to continue charging above 80% in winter to compensate for range loss due to cold weather BEFORE departure.
Keep temperature up to 5 bars for most of the time.
Do not recharge above low battery warning if above 7 bars. It's ok to continue the trip and quick charging until destination.
Rapid charge for short time - I often charged 10 minutes, just to reach destination or next charger. Then charge on 230V.
If battery is warm (6 bars or more) - be gentle - don't floor it, just drive fast, up to 105km/h(65mph) is really ok for gen1.
You won't build up more heat this way and you will lose heat after rapid charging.
Right now it is the hottest weather for my Leaf, 29*C in shade. Battery 29-32*C, 6 bars. I can't get above 6 bars without QC.
So recommendation "keep it between 20%-80%" doesn't hold.
