Current Charge indicates the current remaining capacity of the rechargeable battery in percentage
*1
(%). A fully charged rechargeable battery is 100 %.
A fully charged rechargeable battery of capacity 2600 mAh, for example, with a remaining capacity
of 1300 mAh is displayed as 50 %. However, as the battery deteriorates over time, a fully charged
rechargeable battery is displayed as 100 % even if the fully charged capacity falls from 2600 mAh
to 2000 mAh.
Cycle Count is the number of times the equivalent of 90 % of a rechargeable battery's nominal
*2
capacity is used. Cycle Count is not the actual number of times the battery has been charged and
discharged.
The capacity of a rechargeable battery to discharge degrades over time. When the amount
discharged is equivalent to the nominal capacity, it is counted as 1 Cycle Count.
For example, if 100 % of a rechargeable battery with a nominal capacity of 2000 mAh is completely
discharged in one usage, the Cycle Count increases by 1. If approximately ¼ (500 mAh) of the battery
capacity is discharged in one usage, and the battery is used four times (500 mAh x 4 = 2000 mAh),
the Cycle Count increases by 1.
It is recommended to replace the battery once the Cycle Count reaches 500 times.
Battery Health indicates the capacity of a full charge in percentage (%). 100 % for a full charge
*3
capacity when the battery is first used. A rechargeable battery deteriorates over time after repeated
charging and discharging, and cannot maintain a full charge as a new battery.
For example, if a rechargeable battery has a full charge capacity of 2600 mAh when it was first used,
and the current full charge capacity is 2340 mAh, the Battery Health will be 90 %.
It is recommended to replace the battery once the Battery Health reaches 50 %.
