• Cold start current (CCA, SAE) is  the  discharge  current that a battery  can deliver for 30 sec at a temperature  of -18°C (O°F) without  drop
ping below 7 .2  V. 
Reserve capacity (RC, SAE) is  the  time  required  at + 2rC (80°F) for  a steady  discharge  current of 25 A to reduce the potential  of a fully charged  battery to 10.5 V .
