CCA (Cold Cranking Amps) ratings of typical automotive 12 volt batteries today are in the range of 500-1,000 amps. This is the current the battery can supply for 30 seconds at 0 degrees F and still maintain 1.2 volts per cell. The 166 amp peak at 5% duty cycle would be a piece of cake for these batteries.
