Where,
C : Required storage battery capacity at 25°C
L : Maintenance rate* (generally 0.8)
K1 : Capacity conversion time corresponding to the sum (T1+T2) of Waiting time T1 and Operation time T2 .
K2 : Capacity conversion time corresponding to Operation time T2 .
I1 : Current consumption in standby or idle from the time that power fails until emergency broadcasting
begins. This is the sum of all currents needed by all the units in system consuming power even during
power failures.
I2 : Power consumption during emergency broadcast (the 24V DC current consumption of the entire system)
when 4-wire system attenuators are connected, their current consumptions are also included.
Discharge Capacity Conversion
Time (minutes) Time K (hours)
10 0.333
20 0.575
30 0.820
40 1.06
50 1.30
60 1.55
70 1.80
80 2.05
90 2.28
100 2.50
When capacity conversion coefficients corresponding to the operation time (discharge time) of more than
100 minutes is needed, approximate values can be obtained from the following expression:
Capacity conversion time K = 0.0217 x Discharge time + 0.33 ......... (A)

*Maintenance rate is a correction value used to guarantee needed
battery capacity and satisfy specified load characteristics while
accounting for
conditions. As a general guideline, it is assumed that battery
capacity decreased to 80% of the original represents the end of the
battery's useful life, and therefore a maintenance rate of 0.8 is used
in these calculations.
