The service battery warning started showing too, and stuck around over a week and a few charge cycles.

Its obviously seen some use, but most often, its on AC, or perhaps running down to 50-60% and then charged back up.Ī couple of weeks ago, I opened the computer up in the morning and it was nearly flat, despite having been fully charged when I went to bed. Which might explain why my 2012 rMBP is so haggard : Time and over ~4v, particularly at higher temps is probably a stronger predictor than just calendar age. Of course, being unused, they were probably at ~3.7v or lower for their entire life until I pried open the case. Yeah people say that, but I've been testing 18650 cells from 4+ year old, but unused laptop packs, and most have close to their original rated capacity. These batteries have an expiration date the day they're made. Well, my MBA is nowhere near 1000 cycles and the battery is pretty sad.Ģ582 of 4680 mAh capacity remaining, 55.2%

My late-2013 13" MBP that I got 18 months ago is at 99.5% at 64 cucles, although it was originally 103.5%, so it loses about 3% per year so far.ĬoconutBattery also does iOS devices when they're plugged in now, and I'm a bit worried that after 4 months, my iPhone 6 is at 95% after 80 cycles. No wonder these batteries won't last.īut the expiration date thing is not entirely true: with a battery that's some 6 years old (IIRC) I still get 88% of design capacity after 31 load cycles. After a while, I started getting warnings that the battery was getting too hot, starting at around 33 degrees and eventually reaching almost 40 degrees. But yesterday I plugged in the battery to allow the CPU to run at full speed, and had the latest CoconutBattery monitor things. I have one of these mid-2007 MBPs, and after going through a couple of batteries quickly, I now run it without the battery. As an owner of an oldballs 2007 Macbook Pro with batteries that lasted about a year, I'm very impressed to see the unibody batteries actually live up to their claims
