• The second group of digits (590A) indicates that the battery delivers a current of 590 amps at -18C without the terminal voltage falling below 7.2 volts.
• The third group of digits (90RC) indicates the time in minutes in which the battery voltage falls to 10.5 volts in the case of a 25 amp load and an ambient temperature of 22C.

DIN Labelling
