Model type description
|
• |
Cold Cranking Ampere (CCA): Cold Cranking Amps is a rating used
in the battery industry to define a battery's ability to start an
engine in cold temperatures.
|
– |
The rating is the number of amps a new, fully charged battery
can deliver at -18 °C(-0.4 °F) for 30 seconds, while maintaining
a voltage of at least 7.2 volts for a 12 volt battery.
|
– |
The higher the CCA rating, the greater the starting power of
the battery.
|
• |
RESERVE CAPACITY (RC) : Reserve Capacity is a battery industry
rating, defining a battery's ability to power a vehicle with an
inoperative alternator or fan belt.
|
– |
The rating is the number of minutes a battery at 26.7 °C(80 °F)
can be discharged at 25 amps and maintain a voltage of 10.5 volts
for a 12 volt battery.
|
– |
The higher the reserve rating, the longer your vehicle can operate
should your alternator or fan belt fail.
