Each tab in the charger panel provides different battery
statistics:
Charge Displays charge as a percentage of the
total battery capacity. Also shows time
remaining to full charge.
Health Displays health of selected battery as a
percentage of the charge capacity of a
new battery. Charge capacity (battery
life when fully charged) will decline as a
result of repeated charge cycles, age, or
storage conditions.
Cycle Displays total number of times that the
battery has undergone one full count of
discharge and charge. Recharging after
discharging halfway counts as one half
of a cycle. Recharging after discharging
a quarter of the way counts as one
quarter of a cycle.
Temperature Displays battery temperature (in Celsius
and Fahrenheit) and status.
