Re: Capacity Loss on 2011-2012 LEAFs

Was there are thread about who has the most capacity bars lost? http://www.electricvehiclewiki.com/Real ... 52.5.25.29 had one guy w/6 CBs down.

If the car at https://www.facebook.com/NissanElectric ... 22R9%22%7D is fully booted, that confused guy is down 7 capacity bars. Earlier on he's confused at https://www.facebook.com/NissanElectric ... 22R9%22%7D says he has 3 bars, because he didn't count the red ones.

Hi there,

Sorry if I am not as knowledgeable as some others on here, but I wanted to get your take. We have a 2012 Leaf SL and its in service date was Jan. 3, 2013. I'm trying to estimate how likely it is we'd qualify for a replacement battery before the warranty expires on Jan 3, 2018?

Here are our stats now on leafspy lite: AHr: 47.80, SOH 72%, 384.0V 29,733 miles, 4QCs, 2391 L1/L2s

Its at 10 bars now, been almost a year since we lost the 2nd -- how likely do you think i is we'll see 8 bars by 1/8/18? We put about 10k mile sa year on the car the last 2 years.

thanks!

Ah, good question. Coastal southern California. Doesn't get too hot here but we can start quick charging more. :-)

Took me about 7 months and 10,000 miles from February to October to get to 8 bars from where you're today, or close, but hotter inland LA area. I think you have a good chance to make it given there is more one year left, but QC as often as you can, the sooner you start the better, drive fast and hard to keep the pack warm.

The Leaf has been in hot, Texas climate since originally leased in Sept of 2012. Nissan has ordered a new battery for replacement - likely in December time-frame.


The new battery was delivered to the dealer Tuesday of this week. Replacement is scheduled for next week. The EV group at Nissan gave me the correct delivery information a couple of weeks ago - best to call them if/when your dealer gets approval for replacement.

I just got LeafSpy a couple of weeks ago, so I don't know the actual Ahrs/SOH when I purchased the 9 bar car last January - so the only data point is the 42.73 AHrs/65% SOH when the fourth bar dropped.

We bought our '12 in March of this this year and it was on 11 bars. It dropped to 10 over the summer and to 9 about 3 weeks ago. The 700+ posts is a little daunting to sift through. What is the best process for me to start to inspect the battery and try to get it resolved?

We love the car and could honestly get by with the lower capacity if we had too as my commute is about 10 miles round trip, but I'd like to be able to drive 60 miles without having to charge the 3 or 4 times a month when the need presents itself. At present with the no accessories on the range says 58 after a full charge.

Many thanks.

Allen

You can only monitor battery. If you drop to 8 bars before 5 years and 60 000 miles
you will get replacement. Immediately visit dealer.
During winter capacity loss is very slow. You can not speed it up with normal driving.
You need multiple QC per day (at least 5 of them) or use heater under the Leaf in garage.


You can use LeafSpy with OBD ELM adapter if you want to monitor precisely.
Expect 10-30$.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW

Yes but isn't the warranty 8 years or 100,000 miles? What happens at say 80,000 miles if your range is down to just 10 miles? They won't replace the battery?

The longer warranty is for battery manufacturing defects only, not gradual capacity loss. 5 years/60k miles is the limit for capacity loss in 24kwh Leafs. The 30kwh Leaf batteries are warranted for 8 years/100k miles.

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