• 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 .
