Yes in theory using the 10% to 80% range is best but that limits a 100 mile battery range to 70 miles on a nice clear 65F day and maybe 50 miles if the weather was like yesterday morning at my house. My battery has been recharged about 750 times. I saw a 2011 that had been recharged 7000 times mentioned the other day and still had 50% of its new range.
Our car is for butt moving so it will not see much butt pampering. I am not into abuse of people, animals or machines but the Leaf is a low end EV range wise. Using the middle 70% of a 300 mile battery is very doable for most people but not so much for a battery with a solid 50 to 80 mile range on a charge when you are doing 60 miles daily. Nissan states it is good for 8 years or 100K miles so I am going to take them at their word since they are backing it up with their money.
Your best bet is to charge it to 100% every day and just drive it. That battery doesn't like heat but where you are that's only 3-4 months out of the year. You ought to be able to get 1500 charge cycles out of the battery. That will put you close to the warranty limit. With some management on your part, you ought to be eligible for a replacement battery before the warranty expires. I will warn you that range gets hard to manage below 75%. On the plus side, there are going to be a lot more DCFC chargers available for a boost if the battery is running low.
I wouldn't advise driving down to turtle. Discharging the battery that low doesn't help either the battery or the software. It's good to know where turtle is but you really don't want to go there unless you have to. Charging to 100% occasionally is necessary to keep the BMS honest. Keeping the battery below 90% in the summer is a good idea if you want to extend battery life. If your objective is to have the battery replaced just before the warranty ends adjust your habits accordingly. Keep in mind that Nissan is looking for the loss of 4 bars only. Nothing else matters to them. That will occur somewhere around an SOH of 64%. Use Leafspy to check the value. If you don't have Leafspy, get it! it's invaluable for monitoring the battery.
Thanks for the info. As of 2 days ago SOH= 64.85 and I only hit Turtle mode once when I was 300 feet from the charger. Another time I was at the charger. Turtle happens at around 6 Gids so I try to make sure not to go below 8 when testing for max miles which is around 60 miles in winter driving and some at 70 MPH. The hot seat and steering wheel feels good to my old bones and joints.
In B mode it is really hard to deplete the battery I have found because at that point the Regen can really make Leaf Spy Pro show a bump in SOC.
I do not think the software update has been done so I need to get that done so Nissan can look at it if the 4th bar is lost. The salesman did not get me with the shop but he talked with him and that they said there was no way that battery going not drop the 4th bar sooner than later.
