Last week I got a new battery for my cell phone. One of the things about Lithium Ion batteries is that they have a finite life. The moment they are built they start to loose capability. Unlike some of the older battery types they cannot be refreshed by running them totally dry and then recharging them. In fact it is REALLY bad for a cell phone battery to get below 20% charged. When that happens the battery loosed a chunk of it useful live.
This chart shows how the life of a Lithium Ion battery. Zone A is when the battery has the longest run time between charges and the ability to be charged the most. Zone B the battery somewhat levels off in the runtime and the amount of charge it can hold. When a battery gets to Zone C in its life you start to notice that the battery just doesn’t last as long, until Zone D we are out buying a new battery because it seems that after one call on the cell phone, even when the battery is fully charged, the thing is dead.
As I was thinking about my new battery, I realized that my own energy level and ability to carry a charge is dependent on my age as well. Isn’t it true when we were in High School and College we had energy and could go for days on very little sleep? I played softball, basketball, played in the band, worked a part time job, carried a full load of classes and still had energy to socialize in the evening. For me it seems that I was in Zone B until I was about 45. It is true that now that I’m over 50 I am starting to realize that I just don’t last as long as I once did, I feel like I’m fully charged and just can’t get as much done as I used to. Since I am just entering Zone C in my life, hopefully it is a long season especially since my Uncle Joe just celebrated his 97th birthday and it has only been the last three years that he has been unable to take care of his own yard. But part of dealing with the seasons in our life is recognizing what season we are in and making the best of them.
For you folks with mobile devices, it is rare that a Lithium Ion battery will last more than 18 months.
