What does 120 RC mean on a battery?

RC is a general indicator of how long a new, fully charged battery can continue to operate essential accessories if the vehicle’s alternator fails.

How many CCA does a 12 volt battery have?

12-Volt 12 Ah 165 CCA Rechargeable Sealed Lead Acid (SLA) Battery.

What does RC mean on a battery?

Reserve capacity
Reserve capacity (RC) – helps to power your vehicle’s electrical system if the alternator fails. It identifies how many minutes the battery can supply ample power without falling below the minimum voltage needed to run your vehicle.

How many CCA do I need for my car?

The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels). CCA rating is an indication of a battery’s ability to deliver a sustained amp output at a specified temperature.

Will a higher CCA hurt my car?

Having more potential current available will not hurt the car’s electrical system. It may actually provide for slightly faster starts, with less wear on the starter motor, but in most cases the difference is not significant enough to worry about.

How do you check battery CCA?

To test the CCA with a carbon pile, a battery that must have an SoC of 70 to 100 percent. It is then loaded with half the rated CCA for 15 seconds at a temperature of 10º C (50º F) and higher. As an example, a 500 CCA battery will discharge at 250A for 15s, and the battery passes if the voltage stays above 9.6V.

How do you read battery results?

If your battery is greater than 12.45 volts it is sufficiently charged. Anything below that should be recharged and tested with professional test equipment….Step 3: Read the test results.

  1. 12.66 volts = 100% charged.
  2. 12.45 volts = 75% charged.
  3. 12.24 volts = 50% charged.
  4. 12.06 volts = 25% charged.
  5. 11.89 volts = 0% charged.

What should a 12-volt battery read fully charged?

about 12.6 to 12.8 volts
A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.

Is 800 cold cranking amps good?

A: On average, a battery with 650 CCA is good for the cold climate. An 800 cold cranking amps battery ensures you’ll start your car in any weather.

At what voltage is a 12-volt battery flat?

12.0 volts
12.0 volts or below – At 12.0 volts your battery is considered to be fully discharged or ‘flat’ and should be recharged as soon as possible. The lifespan of your battery will be severely affected if it remains within this voltage range for extended periods of time.
