Had a chance to charge my 2014 S60 (55k miles) to 99% — as high as it goes — before taking it in for routine service, and got 184 RM. So, down 11.5% from the supposed 208 RM when new. Had the service tech check my battery and he said it ranked at 80th to 85th percentile among S60 batteries, which seems about right, given the reports of other S60s with considerably greater degradation.
Also asked how much a replacement battery would cost and was told that a remanufactured 60 battery is currently $16,000. I consider myself lucky that my battery capacity is still enough to do my longer road trip legs. It has shown almost no additional degradation over the last year and a half that I can tell, despite hard use.
• S60, May 2014 build
• 55k miles
• Supercharged 200 times (since I bought it with fewer than 7000 miles on it, don't know about before that)
• Lowest SoC reached on a trip leg: 3% (7 RM)
• 89% 164 RM ("89%" is what the "90%" detent on the charge level always gives me).
• 99% 184 RM (99% is as high as my car goes)
• Normal home charging maximum is 50% to 70%, depending on the season. I don't charge higher than that unless on a road trip, when I sometimes Supercharge as high as 93% to 97% — takes a long time — to deal with long trip legs and freeway speeds. (At home "90%" limits my regen when dealing with long, steep hills, especially when the battery is cool in winter.)
