For optimum service life, do not discharge a battery system faster than the maximum continuous
discharge current or allow the batteries to self-heat beyond 50
℃
. Operation above 50
℃
results
in accelerated performance degradation during the battery’s service life. At low temperatures, the
maximum available discharge current decreases due to increased internal impedance at lower
temperatures.
6.3 Discharge Cut-Off Voltage Limits
When configuring your application stop discharges when the battery system reaches the
recommended discharge cut-off voltage or any battery reaches 65
℃
. To determine the
recommended discharge cut-off voltage for a battery system, multiply the number of batteries
connected in series by the recommended discharge cut-off voltage for a single battery (10 V), as
shown in equation 5.
Eq. 5 (Number of batteries in series) x (10 V) = Cut-off Voltage, battery system
You can discharge the battery system at greater than the maximum continuous discharge current
in short pulses (see specification please) as long as individual battery do not exceed 65
℃
.
During pulse discharges, the battery system voltage can safely fall below the recommended
discharge cut-off voltage. Although you can safely discharge the battery system below the
recommended discharge cut-off voltage, do not leave the batteries below this level.
Recharge the battery at once after it is fully discharged to prevent permanent capacity
loss and damage to the battery.
