First Capacity Bar Loss And What To Expect

Thu Jul 07, 2016 4:42 pm

Recently, I noticed the loss of one of my capacity bars. Instead of twelve bars I now only have eleven. It's downright depressing. Like the loss of a pet puppy. My Leaf is a 2013 with about 25,000 miles on it. I can't remember the last time I allowed it to have full 100% charge. I read that it was bad to let the car indulge in too many 100% charges so I guess my thinking was it would be better if the car didn't have any 100% charges. Instead, I let it sample 80% charges here and there. Anyhow, I wonder what I can expect as a result in this one capacity bar loss?

Add your location to your profile, and you will get responses that better match your environment.

The main thing to expect, is lower total range on a charge.

Charging to 100% is not a bad thing. It actually needs to be done on a regular basis to balance the cells in the battery. Letting the battery sit at 100% for extended periods, especially in hot weather, is what is bad for the battery.

There's not anything to expect today compared to yesterday. The degradation is gradual and you won't notice a day to day difference. You may start noticing it month to month though.

+1 though I'd say you are more likely to notice year to year.

Seasonal changes will mask the loss part of the year, exaggerate it part of the year, and part of the time will be neutral.

Appreciate the comments. Here is whats happened. It has been in the nineties here lately and not likely to change next week. I set the timer so the car could charge during or up to the coolest part of the day, about 6:30 this morning. I set it for 100% charge. I should say that I am the second owner. The previous owner took exceptional care of the car--it still had that 'new car smell' when I purchased it. The dealership here did one of those Battery Capacity Status reports and the car scored very high and good results on the various battery items. That was at about 22,000 miles. Well, anyhow, this morning I checked the range after charging to 100% and was happy to find it read ninety miles in the Eco mode and eight-five on the Normal Drive mode. That put my fears to rest. My routine route drive this morning showed normal electrical consumption. In the future, I think will charge up to 100% at least once a week. Again, thank you for enlightening me on this subject!

I'm now at two bars loss in VA. Here's my recent take on what you can expect as your LEAF loses capacity. Bottom line: it's not the end of the world.

As an 11-month owner of a 2013 SV without quick charging, may I ask how frequently you used quick chargers? I recently crossed 40,000 miles and still have all 12 bars. I also live in the Philadelphia area, and have only recently seen the battery temperature reach 8 bars for the first time.

While there are things you can do to minimize capacity degradation, ultimately it will happen, and your climate is a big factor in that. Identically-used Leafs in Seattle and Phoenix will NOT have identical battery capacities over time. It also appears you bought your car used; do you know where it was originally purchased/leased new?

3 years/25k miles to lose a bar is not out of line for a warmer area; check out my sig line for the details on my former Leaf. I'm in the LA area about 30 miles from the ocean, my Leaf was garaged at home and parked in a parking structure at work, was rarely charged above 80%, and never quick charged as my car didn't have the CHAdeMO port.

Just notice I lost 1 bar as well 54K mi S trim with QC option, in mild weathered San Francisco Bay Area. Charge to 80% at home (clipper Creek 4.8KWh L2), 100% at work (I get free charging at work, L2 Blink chargers 6.6KWh). Only L3 charge hand full of time. Lease the car September 2013, bought the car off in May took advantage of the $7500 lease buy off from Nissan.

Now thinking about getting a base model Model S as the price have lowered to barely tolerable point for me. I have the wifey CFO approval, it's getting the down payment and finance together. Of course, test drive both the Model S and X when I am ready to buy.

The Leaf is kind of gateway drug into EV. May keep the Leaf for my wife to drive around town running errands, she has a 2014 4-Runner Trail which I think should be saved for long trips and off roardng. Then the Leaf can go to my daughter when she's at driving age. I figure at that point the Leaf would be just enough range for her not to get into too much trouble.

I own a 2017 Leaf S, I saw my first bar drop within the first year of ownership at 18,875 miles. It was very depressing when I saw that, at that rate within 3 more years I wouldn't be able to take this car to work and back round trip on a full charge. My round trip to work and back is 75 miles.

Should i be concerned about the rapid battery capacity loss?
