As always, depends upon the heat. If you are in a temperate climate and are quick charging at 5 bars regularly, then no, they probably don't hurt it at all.pipestem wrote:Mine are pretty much the exact same, but with 24k miles and 362 QC. Maybe QC does not matter that much after all.
Your climate is not much cooler (if any) than Phoenix...Relayer1956 wrote:I think I probably have the worst 2015 SL battery degradation of any so far reporting. Here are my 100% charge stats:
Battery Mfg Date: 6/6/2014
Purchase Date: 9/5/2014
GIDs: 206 (73.3%)
Battery Temp: 81.8, 83.5 & 83.1
I am anticipating dropping the 10th bar shortly.
With approximately 0.5AHr loss per month, it appears I am on track to loss the 9th bar before 60,000 miles.
Will report here when I lose the 10th bar.
