Actually, as capacity and peukert's exponant increase the C/20 capacity and
the Peukert's capacity of a battery get further apart. I just checked for a
Trojan T-125 battery using the C/20 and 75 amp discharge data provided off
the Trojan web site. The Peukert's capacity is 376 but the C/20 only 235
amp hours.

Now which one does the E-meter want?
