Discharge and Power Data
Discharge
Capacity
The discharge capacity of Lucent Technologies 12IR125
batteries is directly related to temperature and inversely related
to the discharge rate. The maximum recommended discharge
rate is 125 amperes.
Discharge Cycle
Life
Discharge rate, recharge parameters and depth of discharge all
contribute to discharge cycle life. The most important factor in
determining discharge cycle life for Lucent Technologies
12IR125 and most other lead-acid battery designs is generally
the depth of discharge (capacity removed/capacity available).
The more completely a battery is discharged, the lower the
number of cycles available prior to failure defined as 80% of
rated capacity.
Lucent Technologies 12IR125 battery applications have been
optimized to deliver high capacity per unit volume in
predominately float-standby applications where deep, long
duration discharges are relatively infrequent. Therefore, the
number of discharge cycles which may occur throughout the
battery's life are not considered to be a significant factor in
battery failure. It is not recommended for applications that
require deep and/or frequent cycling.
Caution
Discharge of batteries below 1.75V per cell may result in
recharge abnormalities and premature failure.
