Unnecessary


Yes, but not everyone wants to set a timer every day - they are a PITA. Manually unplugging is sometimes the optimum way to end a charge.
You misunderstand, which might be why you have a recurring negative attitude about this.

1. Set the timer once
2. Charge up when SoC is 20-40%

What is the manufacture date for your car? I have a 2014 SV, manufactured in January 2014, that i bought new. It has 31,463 miles and all 12 bars. I live in Southwest Tennessee ... a climate similar to Atlanta and the areas to the north in Georgia.

jamieo, Our 2014 Leaf is a few months younger than yours. That is great that you have all 12 bars. Can you describe how you have charged? What level? How often? At what SOC?

We are going to start using the timer to try to stay within the 30% to 80% range most of the time when possible. Most of the time the car only travels 30 miles a day.

I bought the car new in February 2015, after it had been sitting at the dealer for a year. For the first year that I owned it, I charged almost exclusively on a 120 outlet in my garage (L1) ... I added an RV plug a year later and got a JuiceBox 40 pro. I've always charged to 100% and charge virtually every night. For the first year, I would be down to 50%-60% or so each day, after my normal commute. this past August, I moved and my commute increased. Now, I get home with 30%-40% charge remaining, and sometimes less, depending on what else I've done. On at least one day a week, I go down to 18% or so, as I drive about 72 miles on a normal Tuesday.

I have not babied my battery, and I always charged to 100%.

I have been mindful of the temerature however, but not obsessivley so. In this part of Tennessee, sometimes you don't have a choice about charging while the battery is warmer than average. I also do not use L3 charging very often, but I do use it when I need to (there's a thread where I've been reporting my battery stats over time viewtopic.php?f=9&t=22312)

I also have a 2014 (man. January). It has just over 37,000 miles and all 12 bars. I bought it from a dealer this past February and have driven it only about 2,000 miles in 4 months. My commute is 1.5 miles by bike.

I charge about equally on Level 2 nearby, and on the 110 wall outlet at home. At home it's fairly easy to stop charge at 80% and I often do. Not infrequently I will allow it to charge to 100% when I've traveled in it out of town and don't get back to the car in time to unplug. The car has been in the MA & CT area all its life. Based on the charge stats, I think capacity is close to 20 kWH. Obviously it's likely to lose the 12th bar this year. But all in all I'm pleased with its capacity. And getting about 4.8 mi/kWH around town these days.

This Leaf did not have the fast charging plug so it was only charged on Level 2 during its 21,000 miles before we bought it, and still only a Level 2 today. We use it almost every day driving about 30 miles on average and charge it every night with a Level 2, 20 amp charger. Range has always shown 90 ~ 95 miles and the battery indicator always shows 100%. The computer shows 4.4 miles per kWh. The car lived its first three years in GA, rather warm climate, but we now live in a cool climate in WA State.

Just last weekend, June 5, 2017, we noticed bar 12 was not on. It has been 3 years, 3 months since the car was purchased. The dealer said this is about normal, 3 years for the first bar to go on a 2014 Leaf.

Does this sound about the right time to loose the first bar on the battery?

Does anyone know if charging less than 100%, (timing the charge and unplugging it when it gets to 80%), can extend the future life of the battery?

What about running it down low a few times? Any chance of getting the battery capacity back or extending battery life?

We will bring it in to Nissan for the first 6 month check in a few months.



your first bar is worth 15%. the next one is worth 6¼ so expect to lose it in a year or two. I would consider using the 80% charging level during Summer. That would help a bit and Summer range will cover your commute easily. You probably have several years before you have to worry about it. I know a guy who has lost FIVE bars and still says 40-45 miles is easily doable.

Well that is a bit disappointing. I would have thought 1/12th per bar. We still show 100 mile range sometimes on 100%. We are going to start charging to 80% when possible. When we got the car, the dealer mechanic said just don't worry about charging it so we were charging to 100% all the time and letting it sit for the night and leaving the next morning on the weekdays. Weekends it was left at 100% for the night and the day. Probably not good. It is cool here in the Sequim Valley even in the summer so that is good.

yeah, charge to 80% during Summer, 100% during Winter. the issue of charging to 100% is HIGHLY dependent on the ambient temps and so no reason to not charge to 100% in Winter.

As far as leaving it charged to 100% on weekends? If the temps were in the mid 40's or less, you did very little damage. Keep in mind, Nissan only charges to 97% so there is a fudge factor as well

When we bought the car in Feb 12, 2017, we only saw 4 temp bars on the battery, except 5 bars when charging on 40 amps in Port Townsend. We only have a 20 amp level two at home. Now that it has warmed up, for the last two months the battery temp has been on 5 bars, even when charging on 20 amps. We are now trying to only charge to 80 - 90 percent in the hope of extending the battery. One thing to note is that we rarely run it down to less than 30%. Should we be occasionally running it low to help with battery life?

Even when we charged in the winter, it was in a garage attached to a passive solar house so the garage temp stayed in the 50's. So not really cold, just cool. In the summer it might not get to 70 even on an 80 degree day.
