Example of using Reserve Minutes @ 25 amps
and the 20-hour rate to calculate "n".
First convert Reserve Minutes to hours, then find the discharge current at
for the 20-hour rating. Finally, use a calculator to solve the arithmetic.
Trojan T-105:
Reserve Minutes = 447 min @ 25 amps.
t
1
= 447 min = 447/60 = 7.45 hrs
I
1
= 25 amps
20-hour rating = 225 Ah
t

= 20 hours
I

= 225 amp hours/20 hours = 11.25 amps
