Cycle life characteristics

CHARACTERISTICS - CONTINUED

e) Open circuit voltage vs. residual capacity

Residual capacity of the battery can be roughly

estimated by measuring the open circuit voltage as

shown in the Figure.

(Test condition)

Discharge : 0.25CA

Cut-off voltage 1.75V/cell

Charge :

2.45 V/cell constant-voltage control

Maximum current: 0.4 CA

Battery life

a) Cycle life

The cycle life (number of cycles) of the battery is

affected by such factors as battery types, charging

methods, ambient temperature, interval between

charge and discharge, or depth of discharge. Typical

cycle life characteristics of the battery are shown in

the above figure. This is typical data obtain from a

well-equipped laboratory.

Cycle times depend on each model of batteries and

may differ from this data when batteries are actully

used in the field.

Expected life is also affected by charge conditions.

For life performance, please check actual charge/

discharge pattern in the field. The life is shortened at

shallow discharge about less than 30% of rated

capacity. For additional inquiries, please contact

Panasonic office.
