1) Cycle Life
Cycle life (number of cycles) of the battery is dependent on the depth
of discharge in each cycle. The deeper the discharge is, the shorter the
cycle life (smaller number of cycles), given the same discharge current.
The cycle life (number of cycles) of the battery is also related to such
factors as the battery type, charge method, ambient temperature, andrest
period between charge and discharge. Typical cycle-life characteristics
of the battery by different charge/discharge conditions are shown by the
below figures.
Notes:
This data is
typical and tested at a well-equipped laboratory. Cycle times are different for each battery model. Cycle times are also different from this data when using batteries
under real conditions.
Cycle Life vs. Depth of Discharge
Constant Voltage Cycle Life Characteristics (Model: TR2.3-12)
Rapid-Charge Cycle Life Characteristics (Model: TR2.3-12)
2) Trickle (Float) life
Trickle life of the battery is largely dependent on the temperature
condition of the equipment in which the battery is used, and also
related to the battery type, charge voltage and discharge current.
The
respective figures below show the influence of temperature on trickle
life of the battery, an example of trickle (float) life characteristics
of the battery, and the test result of the battery life in an emergency
lamp.
