Since crossing 50,000 miles on December 7, 2017, at 47.21 Ah, the reported capacity has increased to 48.24 Ah on Februrary 11, 2018, with about 52,000 miles on the odometer.

So, has capacity loss accelerated from 2.2 Ah/10,000 miles (30,000 mi. to 40,000 mi.) to 2.6 Ah/10,000 miles (40,000 mi. to 50,000 mi.) or has it slowed to 1.6 Ah/12,000 miles (40,000 mi. to 52,000 mi.) or both?
Two weeks later, the Ah reading has dropped 1.0 Ah down to 47.28 Ah. It was 80F one day last week, so I guess it decided to head back down.
Reg, I measured my battery yesterday, first time since 11/1/17, and my reading went up slightly from 45.80 (41,700 mi) to 45.91 AHr (44,700 mi). I have increased my driving slightly (750 mi/mo vs. my previous 500 mi/mo normal), so maybe the battery likes being used more. I fully expect to see degradation increase again next month. I recorded about 2 AHr loss last year, and I’m expecting something similar this year. Hopefully it won’t be worse, though the summer could be brutal with more 115 F temps. I think I’m still on target to lose the 4th bar in 2019, so at about 8 years and right around 55,000 mi.
Here's my seven year anniversary report after charging to 100%:
2011 SL received 8/18/11. I'm the original owner. Paid MSRP (no other choice at the time).
9 bars, 47,754 mi, 75 miles on the GOM at full charge.
AHr 44.22, SOH 67%, Hx 46.43%, 85*F temp, 4.092 V, 96.4% SOC
Extrapolating LeafSpy data collected over the past four years, I'm anticipating 8-bars on May 1st, 2019 (7.75 years).

Thu Oct 04, 2018 1:30 am ... %22R%22%7D has a pic of some in the Seattle Leaf group with only 5 bars.

I don't know his story, but I think I have met him before when I lived in the PNW, so I assume the car's always resided in the PNW. Maybe DaveInOlyWA knows?

'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
'06 Prius

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