2-9 BATTERY STATE-OF-CHARGE DISPLAYS
Batteries equipped with state-of-charge (SOC) displays indicate battery charge status
on a five-segment LCD bar graph readout. The number of LCD segments activated
corresponds to the battery state-of-charge as follows:
Segments State-of-Charge
0 0% (fully discharged)
1 1 to 20%
2 21 to 40%
3 41 to 60%
4 61 to 80%
5 81 to 100% (fully charged)
2-10 BATTERY CAPACITY RETENTION
As shown in the adjoining graph, fully charged
batteries that are stored lose a portion of their charge
due to battery the chemistry. This is normal and
should not be interpreted as battery failure. Storage
at higher temperatures increases capacity losses
while storage at lower temperature decreases
capacity loses.
