Re: The Battery Replacement Thread

Mon Feb 12, 2018 1:08 am

I checked Leafspy today for the first time since getting the new battery installed.

I've driven the car about 2200 miles since the replacement and my stats have improved from when I first picked the car up.

AHr 66.52 (65.47 before)
SOH 100% (100% before)
Hx 102.17% (100.30% before)

I've been babying the battery since getting the replacement by primarily charging to 80%, never letting the car sit at 100% if I need to fully charge, and almost never using the bottom 20% of the charge.

Even though it's cool out I had expected to have the SOH begin deteriorating immediately. Since my Model 3 SR is delayed we'll see how this car holds out during the summer if I decide to pass on the '18 Leaf.

My replacement battery had a precipitous drop in stats in the weeks after it was installed, held relatively steady all winter, and now seems to be magically improving in the warmer weather (!?) Weird, but I'll take it.

My battery was replaced under warranty on June 20, 2017. The stats at that time were:

Miles: 50,134.1
AHr: 66.138
SOH: 100%
Hx: 100.85
L1/L2: 4401
QC: 18

I took a reading today and here is where I am almost two Georgia summers later.

Miles: 61,398
AHr: 62.253
SOH: 98%
Hx: 88.3
L1/L2: 5320
QC: 31

Overall, no noticeable degradation. There was no LEAFspy in 2012, so I can't say how this compares to my original battery. I lost my fourth bar at 42.994 AHr and 48,960.9 miles. The losses thus far work out to about 0.28 AHr/month.

My 2017 replacement battery (Mar 2017), degraded to 96% SOH after ~6 months (Sep 2017).
Then, 6 months later (1 yr), it was at 90% SOH.

My new battery dropped then increased back to 65.5Ahr or so (!) then dropped precipitously again. It's now back down to 62.1Ahr / 87.82 Hx but with 97.35 SOH. (?!)

Weird behavior. I haven't been tracking it nearly as religiously as the pre-warranty days. :)

The amp-hours cycles significantly with temperature as the seasons change here in Houston - at least with my 2 year old lizard battery. In fact as spring warms, the amp-hours has risen by at least 3-4 amp-hours consistently in a couple of months - and have experienced a similar drop as the fall temperatures drop. Overall, it appears I've lost about 11 amp-hours in two years.
