Installed batteries

In the Installed batteries section, shown in Figure D, you'll find detailed information about the battery including the name, serial number, and manufacturer. While the particular battery shown in this screen shot doesn't list the name or serial number, many actually do.

The Chemistry is listed as LION which indicates that this is a Lithium Ion battery. As you can see, the next item in this section is Design Capacity and represents the amount of a charge that the battery was designed to hold. The value is represented as mWh, which stands for milliwatt hours. (Laptop batteries have a voltage rating (V) and milli-Amp hours (mAH) rating and these two ratings are multiplied together to come up with the milliwatt hours capacity.)

The next item is called Full charge capacity and represents the amount of charge that the battery will actually hold. As you can see, in the case of my example system, the full charge capacity is actually larger than the design capacity. I suppose that this has something to do with this being a brand new system. However, on most of the battery reports that I have seen so far, both the design capacity and the full charge capacity have been equal or the full charge capacity has been less than the design capacity.

The last item in this section is called Cycle count and this value indicates the number of times that the battery has used up 100% of its charge. For example, a cycle could be measured each time that the battery has run all the way down and then been recharged. A cycle could also be the result of discharging to 50%, charging to full, then discharging to 50% again. Batteries have a limited amount of cycles to work through before they are considered consumed. Maximum cycle count varies depending on a number of factors, but the battery manufacturer will have a maximum count value listed in the battery's specifications.
