Original Capacity: 74.88 Wh
Current Capacity: 6.76 Wh
As you can see, my Lenovo Thinkpad X61's 8-cell battery, after 727 cycles, now only has 9% of its original full charge capacity. I used to be able to get a decent seven, sometimes even eight hours of use out of the battery, now? I'll be lucky if it lasts 30 minutes.
The laptop has a relatively smart power manager software that seeks to delay the inevitable deterioration of lithium ion batteries by not charging it to actually 100% of 74.88 Wh and also avoiding unnecessary recharging for situations when you unplug and replug the laptop within a few minutes when relocating from one office to another.
But after only two years of intense law school use and abuse - this laptop will need a new battery for it to become mobile again.
Who still wants to buy a Nissan Leaf?
