State of charge
The state of charge indicates graphically how much charge is
remaining in the battery pack. The battery pack continuously
monitors the current consumption of the transceiver and
calculates the remaining hours of use assuming a Tx to Rx
ratio of 1:9.
State of health
Rechargeable batteries have a limited lifetime and a limited
number of times that they may be charged and discharged.
Over time, the total amount of charge that a battery pack may
hold decreases. The state of health indicates graphically how
much charge a battery pack can still hold, relative to when it
was new.
A low state of health indicates that the battery pack may need
replacing.
