BATTERIES
Proper operation of any electrical system or component can be
affected by battery condition. The battery(ies) must meet or exceed
minimum specification for vehicle as equipped and test to that
specific battery's CCA.
Definition of Terms
* Battery Performance Testing
Testing that determines whether or not a battery meets both
vehicle OEM and battery manufacturer's specifications.
* Cold Cranking Amp (CCA) Rating
The number of amperes a new, fully charged battery at
0
F (-17.8 C) can deliver for 30 seconds and maintain at
least a voltage of 1.2 volts per cell (7.2 volts for a
12-volt battery).
* Cranking Amps (CA)
The number of amperes a new, fully charged battery, typically
at 32
F (0 C) can deliver for 30 seconds and maintain at
least a voltage of 1.2 volts per cell (7.2 volts for a
12-volt battery).
* OEM Cranking Amps
The minimum CCA required by the original vehicle manufacturer
for a specific vehicle.
