10.2.3.d Cold cranking current

Cold cranking amps (CCA) (Iх.п.) - according to GOST (DSTU) 959-2002 - is the discharge current that the battery is able to provide at an electrolyte temperature of -18 ° C for 10 seconds at a voltage of at least 7.5 V. The higher this parameter, the better the engine will start in winter. However, due to the increase in the load on the starter, its life span may decrease.

Note
The value of the cold cranking amps depends on the method of its measurement. An approximate correspondence of the values of the cold cranking amps, defined by different standards, is provided in the table below.
