My car has just over 14,000 miles and I am down to 91% on the GID meter now. Not very good for a car that is less than 2 years old.mkjayakumar wrote:after 17 months of ownership (and I guess around 5 months sitting in the dealer lot from Sept through Feb, 2011), after 18,800 miles lost my first capacity bar at 232 Gids at 100% charge.
My Gids have been falling like a rock from 252 to 232 in a span of last 6 weeks
It all depends on how warm the weather is at your location.nerys wrote:is this kind of degradation in battery performance normal?
Lucky you. My 80% charges run to 204. My 100% charge is 251. It still gets me to my destinations and that is what counts.evnow wrote:I've been geting 276. I once got 279.
But my 80% charges have all been 231.
Anyway after 100% charge the SOC meter goes down so fast, it hardly matters whether we get 276 or 281.
Alas 3-1/2 years after first reporting my degradation on this forum (and not being believed by many of you I might add.. at first anyway ) I have finally received my new battery. I could have sooner but chose to wait as long as possible to maximize my ROI on the first battery and ensure I get the latest chemistry. I had to leave town hours after taking possession so no 100% charge numbers yet, but at the dealer I read 270 gids on a 89.8% SOC. Assuming full charge gets me to 96% that should be 288 or so gids! Oddly, the pack voltage was 393.9V which prior to the swap was what I saw on a full charge so maybe the SOC reading was off. Once I get back I'll find out. Maybe I will finally get my 281! Other details from the sample are: 99.8 HX; 100% SOH; 66.14 AH.TickTock wrote: Posted: Sun Oct 02, 2011 10:45 am
I just found this thread and spent the last 2 hours slogging through all the history. Very interested in the subject since I cannot seem to come even close to 281. 80% charge takes me to ~195 and 100% charge takes me to ~240. At least the ratio 100/80 is within error bars but the high value is disturbing to me. Particularly since I only get ~46 mile from 80% to LBW (no freeway). I am in PHX and up until mwalsh's last post was thinking temp could be my culprit (I start the charge at 6pm when the garage is still ~100F). However, last night I plugged in at 11pm (garage was considerably cooler) and still hit only 197 gids and 386V on an 80% charge.
Great news, congrats! Look forward to reading more posts from you on the topic, time permitting.TickTock wrote:Alas 3-1/2 years after first reporting my degradation on this forum (and not being believed by many of you I might add.. at first anyway ) I have finally received my new battery.
