Battery Terminology

Battery Identification Plate Terms:

  • V (Volts) –

    This is the voltage that the battery will supply. Typically this will be 12v or 24v in relation to automotive or marine applications.

  • Ah(Amp hours)  –

    This is the amount of time the battery could continuously supply a current. For example a battery supplying 70Amps-Hours at a current of 3.5 Amps means that the amount of time this battery could continuously supply a current of 3.5 amps to a load would be 20 hours (70Ah/3.5A).

  • A (Amps) –

    This is the amount of electricity flowing.

  • CCA (Cold Cranking Amps) –

    This is the ability of the battery to deliver a cranking current at 0°C(32°F). This is calculated the same as the CCA rating but at a higher temperature.

  • Reserved Capacity Rating –

    This is the length of time a fully charged battery at a temperature of 26.7°C (80°F) Can supply Amps before the voltage falls below 10.5V.
