Re: Is the usable range applicable to all Li-Ion Batteries?

As far as I know the consumer electronic devices use the full capacity of the Li-Ion batteries in order to maximize the time the device can run on a battery. This is why it is typical for a consumer device battery to last about 2 years.

Cars have different requirements - batteries must last 10 years with 20% maximum drop is capacity. I own Chevy Volt and GM states that the actual battery capacity of my Volt is 16.5KW/h but the usable capacity is only 10.5KW/h.

Maybe in the future the laptop/smart phone manufacturers may give the consumer an option to select how much of the battery capacity to be used in order to maximize battery life. I am replacing my laptop battery every 2 years and even then during the second year the capacity drop is noticeable.

Is the usable range applicable to all Li-Ion Batteries?

Intersting technical article. I have the question about the usable range. Is the 60% usable range applicable only to HEV batteries OR for all Li-Ion battery used in notebook/tablets/smartphones etc?

If true, then IMO manufacturers should mark down the efective capacity of the battery as 60% else it is intentionally misleading the consumers.

Like many of you, I was saddened to hear the news of Leonard Nimoy's death. His Star Trek character Mr. Spock was an inspiration to many of us who entered technical fields.
